Colour laser multifunction printers rarely handle duplex print and there are still plenty that don't offer printing from and scanning to a USB drive. Samsung's CLX-6220FX is a workgroup level multifunction which does both of these things and boasts a print speed of 20ppm in both colour and mono print modes.
This is a big, bulky printer, weighing over 35 kg and standing 650mm high off the desktop. It's the kind the machine you need two people to position and to leave in one place.
The machine's layout is pretty conventional, with a large, duplex Automatic Document Feeder (ADF) set on top and a full-width control panel at the front. This includes a fully bitmapped, backlit LCD display, though for most of the time it displays four lines of text. The controls are well laid out, with a number pad for fax dialling, a control ring for navigation and large buttons for starting and stopping scans and copies.
There's a front panel USB socket and the machine can display a file tree, so you can select a file to print or create one from a scan. It can scan to JPEG, TIFF or PDF formats and print from those three and BMP and PRN files, too. The USB drive must be formatted as a FAT16/FAT32 device.
The main paper tray at the bottom of the front panel holds 250 sheets and there's a 100-sheet multipurpose tray available when you pull down the tray cover from the front. A second, optional, 500-sheet tray fits under the machine, if you need greater capacity. At the back are sockets for USB and Ethernet.
The CLX-6220FX is compatible with Windows and OS X, and you can also download drivers for Linux and UNIX. Support software includes Samsung's oddly named SmarThru scanning utility and emulated drivers for both PCL and PostScript.
The four drum and toner cartridges slot in vertically, one above the other, and are easy to access, once you've pulled down the front cover. The transfer belt is attached to this same front cover and is easy to replace, though you only need do this every 50,000 pages.
