The Konica Minolta BizHub C451 is an exciting prospect for the medium sized workgroup. Priced to sell in a competitive market, it performs well, and offers a lot for the money.

While there are many full color laser multifunction’s on the market, they don’t come as well featured as the BizHub C451. It can handle printing, copying and scanning, and performs them all with ridiculous ease. There is also the option to add faxing to the mix for a full multifunction machine.

Connecting the device is via USB or ethernet. The USB option is the quickest to set up, but offers slower transfer speeds than ethernet. Networking the device was also straightforward but took a little longer. It was soon auto-discovered on the network once powered up, and once the drivers were installed we were good to go.

The control panel is well designed and easy to understand. There are large buttons that allow you to select printing, copying and scanning, but the full color LCD steals the show. It is one of the clearest and brightest screens we have seen. It allows you to fully control every aspect of the device from its easy to follow menu system.

The output quality is very good, with pages being produced at a rate of 45 pages per minute. The text reproduction was outstanding in our tests with very crisp edges and no jaggies to be seen. Grayscale was smooth and images was very good overall. Color printing was superb considering this is a laser. Images and photos were the highlights, both printing and copying. The color reproduction was accurate and there were no overtones, or spill anywhere.

Paper is held in a group of four drawers at the front totaling a maximum of 3650 sheets. Replacement toner cartridges can produce 40,000 pages in black and 27000 in color. Considering a black toner is on $45, that constitutes a significant saving in running costs over many other manufacturers.

For medium-sized businesses who need a hard working multifunction device the BizHub C451 is a worthy contender. It produces documents of a quality suitable for almost any use. There are enough options and cost saving reasons to consider the C451 as a long term companion in your office.

The Canon LaserClass 710 is a great fax for business. It has many features that are generally restricted to machines at a much higher price point to this one and performs just as well. Its economical enough to be worth a look when you next need to buy a multifunction.

The Canon LaserClass 710 is a monochrome laser fax with copying, printing and scanning built in. Its a variation of a theme in that this is predominantly a fax with other capabilities. The traditional multifunction has been primarily a printer, copier then fax and scanner.

Fax features like broadcasting, dual access, built-in memory, an automatic document feeder and auto dialing make this a versatile machine for a busy office. The 33.3k modem can send a standard sheet in a little under 3 seconds while the built in memory has enough capacity to remember 500 pages of received faxes, which is expandable to 40Mb, which is enough for around 1000 fax pages.

There is also a 20 page automatic document feeder that may appear flimsy, but is much better constructed than it appears.

Copy quality is good, text was a real standout, with clean crisp edges even when printing or faxing at the lowest points. Simple images or graphics are rendered pretty accurately with the grayscale making short work of color images as easily as monochrome ones.

Dual access is a nice feature to have. It lets you load and prepare faxes even when the machine is already printing, faxing or copying. This allows you to get on with other things while not having to wait for it to finish. The fax has all the other features you would hope to see. Plenty of auto dials, fax forwarding, broadcasting, speed dialing, data/voice switching, configurable cover sheets and document resizing and so forth.

Coupled with a decent array of printing and copying features, this makes the device quite a capable one in most scenarios. Cartridges for the Canon LaserClass 710 are quite reasonably priced. A starter comes with it when you get it, and replacements are around $30 for a toner that is good for 4000 pages.

To sum up, the LaserClass 710 is an decent purchase for the small office.

The Lexmark Optra T620 is a monochrome laser printer suited to the home or small office market and adds a little more variety to Lexmark’s market presence. The company is a powerhouse when it comes to producing good quality printers. Once known almost exclusively for their high quality inkjets, it didn’t take them long to make an impact onto the laser market. Now Lexmark easily competes with the heavyweights like Brother and Xerox for position.

Installing the T620 is as easy as getting it out of the box, installing the toner cartridges and connecting it. Connect to a computer via USB, or network if you have the DN version. It works with all operating systems, including many flavors of Linux, and the driver suite is easy to install too. The web-based control panel makes maintenance simple and allows you to modify many printer settings from the desktop.

Considering the fact this is a laser that prints at 30 pages per minute it offers good value for money. The initial purchase price is reasonable as are the running costs. You can pick up a toner for around $70, which will last up to 30000 pages. The duty cycle is an amazing 100000 pages too, which spans a whole raft of markets. It’s cheap enough for the home user or SOHO market, but capable enough for the office or workgroup market too. This continues Lexmark’s trend of trying to cover as many bases as possible without compromising on any of them.

As for the print quality, text is printed clean and clear, with straight lines and the toner appearing black instead of the dark gray that plagues some lasers. Graphs and images are just as good, with an even spread and accurate grayscale reproduction. Our test document is 24 pages long and includes everything it is likely to meet in daily use. It is a real test of a printers capabilities, and sorts the men from the boys in no time at all.

The T620 is a solid monochrome printer that offer great flexibility and value for money. This device is ideal for the office or home worker that wants good quality prints without a hefty price tag. Who want a good quality, reliable device that won’t let them down.
