Introduction

I am reviewing the Brother MFC-6490CW multifunction inkjet printer which is one of the first products of its type to offer A3-size paper handling. This may appeal to you if you are likely to be running-off large spreadsheets, “download-to-print” display signage and promotional material, maps and the like on these large paper sizes.

Recommended Retail Price: AUD$529

Inks:

Black: AUD$39.95 / cartridge (450 pages) 

Black – Double yield : AUD$59.95 / cartridge (900 pages)

Each colour: AUD$19.95 / cartridge (325 pages)

Each colour – double-yield: AUD$35.95 (750 pages)

Can scan or copy A3 documents using its automatic document feeder

Paper handling

Brother has moved away from design practices that are common with most inkjet printers. First, they have used a U-shaped paper path which is similar to what is used in Hewlett-Packard inkjet printers. Here, unused paper is located under the output tray rather than behind the printer.

This has allowed for a design improvement where the paper is loaded in two removeable “cassettes” similar to how you load paper in to the typical office photocopier. These trays can hold both sizes of paper, but have to be expanded for larger sizes.

Copier-style paper cassette

It can be fussy about which tray holds A3 paper, especially if the paper to be used is of a special type like glossy photo paper. As well, the unit will not be likely to work reliably if you load a small amount of paper in any of the trays, which you may do if you are using occasionally-used media.

The other key difference is the use of an Epson-style “piezo” inkjet mechanism where the ink is pumped to the print-head to mark the document. This is in contrast to how Hewlett-Packard, Canon and others heat the ink in the printhead to make drops fall on to the paper. There can be reliability issues with this kind of setup if you allow the ink cartridge to run bone dry because of air-locks but they can be rectified by your running the printer through a few head-clean cycles to get the ink flowing again. You can do this by pressing “Ink Management” on the control panel, then selecting “Cleaning”.

Brother have taken this further by locating the ink cartridges away from the print-head and using “capillary” hoses to pipe the ink to the print-head. The Ink cartridges are located behind a door on front of machine. One useability advantage is that you don’t need to lift a heavy lid to replace ink cartridges.

Network Set-up and Functionality

This printer is capable of working with either an Ethernet or 802.11g WPA2-compliant wireless network. It can support quick wireless-network setup with WPS-compliant access points and routers but it supports conventional WPA-PSK networks by requiring you to enter the passphrase using the numeric keypad in a manner similar to entering a text message on a mobile phone.

You can use the network for printing and scanning, whether initiated from the destination computer or the unit’s control panel. This will require that you use the Brother software that came with your printer in order to run a “scan monitor”. You also have “print-to-fax” and “fax-to-computer” abilities including the ability to allow the unit to work as a standalone fax for receiving faxed documents if the computer is down.

Walk-up functionality

Copying

The unit has just about the functionality that was expected of a mid-range office copier sold through the 1980s plus can do this with colour.

Here, you can enlarge and reduce originals, with preset ratios for enlarging A4 originals to fit A3 paper and reducing A3 originals to fit A4 paper for example, It also has a “book copy” optimisation mode for copying out of bound materials by using digital trickery to eliminate dark edges and skewing that occur with this kind of material.

Fax

This multifunction printer has all the support for most shared-line PSTN fax setups like Faxstream Duet and similar distinctive-ring services, telephone answering machines with proper end-user experience, as well as the dedicated-line setup. This is a boon for small businesses who are unable by cost or installation issues to set up the traditional separate fax line.

This unit is the first inkjet all-in-one that I have reviewed that provides proper “scan-then-send”  memory transmit for many fax jobs. This allows you to do things you are used to with a well-bred fax machine like scheduled sending (send overseas faxes to arrive at their machine “their” morning) or continuing to send documents to other destinations when one or more destinations is temporarily unreachable.

Print from camera cards

The unit does well with printing from camera cards but, like a lot of its peers, it “holds” the memory card for the whole of the print job even if it is just one image rather than copying the image to memory and releasing the card. This is simply because most of these machines don’t have enough memory for working with print jobs efficiently.

Printing tests

Graphics printing

I tested the Brother printer with a Transport For London transport map which covers the London “Tube”, “Overground”, Docklands Light Rail and other rail services covering Greater London. This map, which I have downloaded as a PDF file from the TFL website allows me to assess graphic colour handling (service lines) and printing and intelligibility of small detail (station names).

From this, it was able to work with small detail but can be hard to read with very small detail. For colours, they aren’t as vivid on plain paper unless you make sure that you specify “Vivid” in the colour option when you configure the print driver.

This isn’t an issue when working with glossy paper because the colours come up more vivid and more contrasty. I have had this printer print a photograph of some people and it handles the flesh tones properly. This is something that I assessed because the A3 page format may also appeal to those of us who are turning out rough drafts, mockups and the like for publishing of magazines and similar work.

Of course, photo-optimised paper yields the best results with more contrast and vivid results. If the work isn’t photo-based, the printer would work best with coated inkjet presentation papers for this kind of work.

Limitations and Points of improvement

The colour print output for graphics printing could be improved when you use plain paper. It is because most of us will work with plain paper either to print “download-to-print” onsite promotion material or run preliminary proofs on to plain paper through a project’s approval cycle. This could be achieved through a “proofing” or “plain-paper graphics” mode which optimises for this kind of use.

The unit could benefit from a “manual bypass” tray so you can load a few sheets of a particular kind of media without needing to empty out one of the trays every time you need to use specific media or do manual duplexing.

The paper-size auto-detect function could be made more reliable so you don’t have to re-determine the paper size through the control-panel or print driver menu if you want to use different paper sizes and types in any of the trays.

An automatic duplexer could be worth its salt as we are being encouraged to print routine office documents on both sides of the paper in order to save paper.

As I have always said, these printers need to benefit from more flash memory installed in them and used for holding pending print jobs. This particular unit would benefit more because of its A3 printing capability where these jobs can take a long time to turn-out. The cost associated of furnishing this memory is coming to the point where it will be ridiculously cheap to provide the technology.

Conclusion

This Brother MFC-6490CW is one of the first colour all-in-one inkjet printers on the market that can print to or scan from A3 or similar paper and this feature alone has impressed me. It is a good “all-rounder” for an operation where there is a desire to print to A3 but size is limited

My comments

I have observed other countries like the UK and France push on with next-generation broadband Internet developments and they have taken various initiatives to achieve this goal.

In some cases, most notably in the UK, local communities had set up localised next-generation broadband deployment for villages and other areas which wouldn’t be serviced by this kind of broadband, let alone any broadband service. As well, a lot of European towns are “wiring up” with some form of fibre-based next-generation broadband and there has been efforts in place to assure competitive service to the customer’s door.

Similarly, Finland took the bold step of having broadband Internet with a minimum speed of 2Mbps declared as a universal service in the same manner as a home telephone or mains electricity.

At the moment, we have situations where people in the country cannot get proper broadband service either through issues like distance to the exchange or very old telephone infrastructure; and we have a common situation where people have to count bandwidth used because of ridiculously expensive Internet-access tariffs and quotas. In some cases, we have situations where multimedia Internet like Internet radio or YouTube streaming video cannot be enjoyed especially during the late afternoon in a metropolitan area due to poor bandwidth allocation.

Is the Coalition intending to provide us with a lesser-standard next-generation broadband service or why are they simply doing this? If there is an alternative solution being proposed for an improved-technology broadband infrastructure, it needs to be cheap to maintain, including low failure rate; cheap to adapt to changing demainds as well as being cheap to establish. It also must be able to provide robust always-live broadband-class Internet service to rural and remote households as well as more dense communities. Finally, the service must see a decent increase in value for the amount the customers are willing to pay.

Whoever gains power in the Australian Federal Government should look at what the UK, France and Scandinavia are doing to assure their citizens of proper value for money as far as broadband Internet service is concerned.

BBC News – Microsoft announces Windows tablet PC plans

My comments

Windows has provided for tablet and touch computing abilities ever since the Windows XP operating system where there was a special “Tablet PC” edition delivered only with computers that used stylus-driven “tablet-style” operation. These computers came in the form of a “slate” where the only user interface was the stylus-operated screen or a “convertible” notebook computer that can be operated as a conventional notebook computer or a “tablet-style” computer just by swivelling a stylus-operated screen 180 degrees. Most of these computers weren’t available in price ranges that most people would consider when it comes to buying portable computer equipment.

They didn’t extend the availability of this operating system to other “tablet-style” or “stylus-driven” setups like interactive whiteboards, “digitizer” tablets or display and light-pen / interactive pointer.

But, when Windows Vista came on the scene, Microsoft integrated touchscreen and stylus-driven “tablet” operation as part of the operating system for all of the mainstream versions. This has opened up the floor for more touch-enabled computer setups or the ability to provide such setups in an aftermarket manner. Windows 7 has extended this further with the support for multitouch screens, again baked in as part of the mainstream versions.

Apple has cast their first “punch” in the fight for commodity-priced touchscreen computing devices with the arrival of the iPad. This has been built on “consuming” material that is normally distributed as print material and, in the case of periodical content, uses client-side “apps” delivered through Apple’s iTunes App Store to “draw-down” the material.

Android and, now, Microsoft have started taking action in providing a platform that does what the Apple iPad does but in a more competitive way for both customers and developers. Microsoft has, on their side, an increasing array of “netvertibles” (netbooks with swivel touch-screens) and low-cost convertible notebooks as a hardware starting point and the touch and tablet functionalities in Windows 7 as a software starting point. They also have been known for establishing an affordable and accessible software-development infrastructure ever since the company started with the BASIC interpreter for the Altair microcomputer in the 1970s, by providing the Visual Studio software-development suite which can allow programmers to write touch-enabled software.

Microsoft could then provide extra “shell” functionality with Windows 7 to enable full touch operation but they will need to work this in so it can work with low-cost hardware in order to make their platform affordable for most. This platform would be like the Android platform where many different hardware manufacturers provide different units that run this operating system.

Personally, the “tablet” computer race will become like what has happened during the late 1980s when there were at least five GUI-based operating platforms on the desktop computing scene. What then happened was that some of the platforms “fell off the branch” or serviced particular user classes, as certain platforms became dominant in mainstream computing life.

As I have said before. there has to be standard interactive “electronic hard copy” platform that permits “publish once, read anywhere” content authoring with the full benefits that these tablet computers offer for the new platform to succeed.

NETGEAR Adds Gigabit PoE Smart Switch – SmallNetBuilder

From the horse’s mouth

NETGEAR GS110TP Gigabit PoE switch product page

NETGEAR GS-110TP Gigabit PoE 8 Port Smart Switch

My comments

The concept of VLANs and quality-of-service functionality is now become increasingly relevant to the home and small-business network now that the “single-pipe triple-play” and “next-generation” broadband Internet services are either here in your market or are coming around the corner to your market.

What are VLANs

The VLAN is a separate logical network path within a physical network medium, such as multiple SSIDs from one Wi-Fi access point serving different networks or a HomePlug setup with multiple Network Passwords for different networks. Most business-grade Ethernet switches offer this functionality in order to have particular Ethernet sockets associated with particular logical networks. It is used in many network applications such as interlinking a business with multiple premises through one multi-tenant building or providing Internet-only “guest access” service to business networks.

Now the VLAN is becoming common in small networks as part of either providing “guest access” or “hotspot service” to the Internet without encroaching on the security of the resident network; or providing dedicated “fast-lanes” for quality of service when it comes to A/V streaming or VoIP service.

NETGEAR’s role in this equation

Now NETGEAR have provided the GS110TP Gigabit Power-Over-Ethernet Smart Switch which is an 8-port switch which offers this functionality and Power-Over-Ethernet to all the ports for US$260. This is similar to how this company offered 5-port and 8-port 10/100Mbps Cat5 Ethernet hubs and switches at prices affordable for most people when the idea of home networking and broadband Internet came on the horizon in the early 2000s. Then a few years later, they offered 8-port 10/100Mbps switches with that had 802.3af standards-based Power-Over-Ethernet supply functionality on four of the ports, again at a price that most users can afford.

It may be easy to think of this unit being a candidate “central” switch when you wire your premises for Ethernet and want to make it future-proof for these new requirements. There have been some concessions to allow it to work properly with “triple-play” by the use of a default VLAN matrix with one VLAN for regular traffic, one for VoIP and one for video traffic. There is some “automatic-transmission” logic that shifts data to the different VLANs based on whether the data was primarily multicast in the case of video or one of a few VoIP protocols in the case of VoIP.

The main problem with this is that this switch wouldn’t work in a “plug-and-play” manner with “edge” devices that use certain VLAN setups or QoS methods to assure video and VoIP quality-of-service. For example, most of the “n-boxes” (Livebox, Neufbox, Freebox, Bbox, etc) used by French “triple-play” service providers as network-Internet edges have one Ethernet port for video traffic and three Ethernet ports for regular traffic. These units would expect you to connect the IPTV box to the “video” Ethernet port and you may end up with QoS or installation difficulties if you used this switch with them.

Limitations with this class of switch

For these switches to become easier to implement in a home or small-business network, there would have to be standards that allow an “edge” device to communicate its QoS and VLAN needs to these switches. This may be important if the “edge” device is managed by the service provider or is part of the provisioning chain that a service provider uses.

This may also include the flexible installation and “at-will” relocation of devices like VoIP handsets or IPTV devices as well as the support for multiple devices of this type across an Ethernet backbone. It also includes the support of multiple cascaded switches such as “regional” switches in other parts of the building or other buildings.

Other benefits to take note of

One bonus that I like about this switch is that it has offered 802.3af-compliant Power-Over-Ethernet across all Ethernet ports which allows the Ethernet cable to be a power cable as well as a data cable.This technology, which I will cover in a separate article on this site, has been pitched at business networks as being suitable for powering Wi-Fi access points, VoIP telephone handsets and IP-based surveillance cameras with one cable and from one point. Infact, NETGEAR have released an 8-port “regional” smart switch that has similar QoS and VLAN functionality but can be powered from this switch or other standards-based Power-Over-Ethernet networks.

Another feature that also appealed to me about this switch is that a unit of this price was equipped with optical-fibre LAN connectivity which can reduce the cost of using optical-fibre as a high-reliability long-distance link between buildings, especially on large properties. 

Conclusion

This is another example of NETGEAR offering technology that is deemed “large business” at prices that home users and small business can afford.

A few years ago, the VESA consortium who manage standards concerning video display equipment have released the DisplayPort video connection standard to connect a computer or similar device to a display. This has yielded increased improvement over the legacy VGA, DVI and HDMI standards that are currently in use for this purpose.

At the moment, it has been mainly deployed by Apple in their recent-issue Macintosh computers and monitors and I have known that the iMac all-in-one computers have the ability to work as a DisplayPort monitor. Now, other manufacturers are releasing laptop and desktop computers as well as aftermarket graphics cards equipped with this connection in to their model lineups. This is also being augmented with a trickle of monitors and “business” projectors that come with this connection and this trickle will turn in to a flood as this connector comes down the model lineups.

Improvements

Small-size connector

There is a standard connector that is similar to a USB plug for applications where space doesn’t matter like display cards or most regular monitor and projector designs. This connector also has a “latching” design that allows for high-reliability connections in applications where this is desired.

Then there was a “MiniDisplayPort” connector that is half the size of this connector and is intended for applications where space is limited like laptop computers, sleek monitors and ultra-low-profile computer housings. This is actually the standard being implemented by Apple in their current-issue Macintosh platform hardware.

Single pipe

This standard, like the SCART and HDMI video-connection standards, allows for a single pipe for high-resolution video, digital audio and bi-directional communications. Some applications like multi-function monitors with integrated sound, Webcams and USB hubs; touchscreen displays and projectors with integrated cursor-control functionality will benefit from this functionality because there is only one cable needed between the host device and the display.

The latest version (1.2) of this standard also allows for multi-display setups from one connection on the host, whether as a daisy-chain or in a “hub and spoke” manner. This then allows for simplifying multi-monitor display arrangements or monitor / projector setups.

It is also worth knowing that the DisplayPort standard also allows for IP-based network connectivity between the host and the display, which could benefit those displays that have some form of network functionality.

Increased performance

High-resolution, High colour depth (digital photo and video)

Increased distance between host and display

The distance between the host device and the display has been increased to 15 metres without the need for repeaters or amplifiers. This would benefit large video-display setups where the display computer would need to be away from the display screen or projector unit, such as meeting rooms, churches, cinemas and the like.

Adaptors available for legacy displays

If you buy a DisplayPort-equipped computer or retrofit your desktop computer with a DisplayPort-equipped video card, you can still connect your computer or video card to your existing monitor. This is feasible through the availability of DisplayPort – VGA / DVI / HDMI adaptors.

Issues to be careful of

Use of DisplayPort – HDMI adaptors

If you want full proper HDMI operation such as “single-pipe audio” with a DisplayPort-HDMI adaptor, you will need to make sure that the DisplayPort host computer is capable of DP++ behaviour. This is to ensure that the proper logic is going to occur between the host device and the HDMI display setup which may include a separate HDMI “sink” device for sound like a home-theatre receiver.

DisplayPort 1.2 multi-display setups

A DisplayPort setup which is established in a daisy-chain fashion requires a DP 1.2 host at the head of the chain and DP 1.2 monitors down the chain, but a DP 1.1a monitor can be used as the last display in the chain. Alternatively, DP 1.1a monitors can be used as the “spokes” displays in a DP 1.2 setup if they are connected directly to the hub.

It is also worth knowing that the DisplayPort 1.2 multi-monitor setups support “multi-streaming” with displays showing different images from one host. This can suit most multi-display applications such as editing environments, “extra-wide desktops” or “operator screens” for projector setups where each monitor must have different video.

What to look for

If you want to make sure that your system can support the display requirements of now and the future, make sure that the display subsystem can support DisplayPort 1.2 with DP++ functionality. This can cater for multi-screen displays, the current crop of HDMI-equipped display and audio hardware amongst other things.

Whenever you buy or specify a DisplayPort monitor for a multi-screen display or as an “operator screen” for your DisplayPort projector, make sure that it supports at least DisplayPort 1.2. You can get by with a DisplayPort 1.1a monitor or projector at the end of a “daisy-chain” setup on as a “spoke” from a hub-based setup with a DisplayPort 1.2 hub.

Conclusion

Once you are aware of the caveats outlined above when buying or specifying DisplayPort hardware, you can be sure that you can benefit from the DisplayPort standard offers.

thinkbroadband :: Vtesse Broadband bring next-generation broadband to Hertfordshire

From the horse’s mouth

Vtesse Broadband – press releases

My comments

The initiative has been taken again to establish full broadband service in the UK countryside. This time, two villages in Hertfordshire, north of London, are equipped with fibre-to-the-cabinet broadband with sub-loop unbundling. The villages, Birch Green and Hertingfordbury, are located too far from the local telephone exchange for guaranteed high-speed ADSL broadband Internet service, so Vtesse have established a fibre-optic backbone for both of the villages and set up the cabinets there.

Another step that has been taken is to have customer feedback to determine where the demand is and where there is poor coverage. The network has been made future-proof so that they can provide fibre-to-the-premises service when the time comes to provide that level of service.

I had a look at the Vtesse website and was impressed with the network-Internet “edge” router that customers would be supplied with as standard. It is a Comtrend ADSL2/VDSL2 wireless modem router that doesn’t just work with 802.11g like most provider-supplied equipment does. Instead, this unit can work with 802.11n Wi-Fi network segments

Again, what I am so pleased about is that this is an example of small companies in the UK have taken the initiative to provide full-ADSL-quality to “next-generation” broadband to the “backwaters” of that country. This then puts farmers and small businesses in those towns on a competitive level with those that have proper broadband Internet service and with the big business operators.

Fujitsu Lifebook TH700 brings convertible tablet magic at a more affordable price — Engadget

My comments

I had previously mentioned in this blog about a “netvertible” computer design which is a netbook with a touch screen that swivels, being considered an affordable Windows-based alternative to the Apple iPad.

Just lately, Fujitsu have upped the ante with a convertible subnotebook / ultraportable computer that has a “convertible” touchscreen design and have pitched it at a more affordable price. This is showing that the convertible touchscreen is appearing in the netbook and subnotebook / ultraportable classes of Windows-based portable computers which represent affordable implementations of this technology and as the cost to integrate a touchscreen into a laptop-class computer reduces, more of the computers in this class will end up with a swivel-head “convertible” design for a significantly-reduced premium.

Now, the only step that needs to happen for them to convincingly make Apple take notice would be to see e-publishing platforms that are used with the iPad be available for the Windows 7 platform. This is so that publishers can achieve the goal of “e-books”, “e-newspapers” and similar publications in a “design once, view anywhere” manner with their rights protected.

As a blog writer, I would like to see a heterogenous environment exist for tablet-based e-publishing that allows for innovation, competition and affordably-priced user-improvable equipment.
