In many ways this all-in-one is the business equivalent of the PIXMA MP520 we looked at last week. Both have very similar purchase prices and where the MP machine includes memory card readers, a colour LCD display and a second paper tray, this one includes an Automatic Document Feeder (ADF) and fax facilities.
The PIXMA MX320 has the now familiar design with an angled surround at the top, into which the control panel is set. In the middle of the surround is the ADF, complete with a fold-over feed tray, which improves the machine's already clean lines.
There's just a single paper feed path from a fold-up support at the rear to the inside of the machine's front cover, which folds down to become an output tray. In a clever little innovation, Canon rigs this front cover to drop down automatically, should you forget to open it before starting to print.
The control panel is well laid out, with three large mode buttons on the left and black and colour copy buttons on the right. In between there's a fax number pad and a two-line by 16-character mono LCD display. In Canon's publicity material this display appears to show black characters on a white background, but in fact it's a fairly low-contrast standard blue on green, with no backlight, which doesn't make it that easy to read.
While there's no colour LCD display, nor memory card slots, you do get a single USB socket at the bottom right of the front panel, which doubles as a PictBridge feed for digital cameras. You can also use it to scan directly to a USB drive, which is a handy extra.
The flatbed scanner mechanism uses a Contact Image Sensor (CIS), but still gives relatively good black and colour page images. At the back are sockets for a fax line and for a phone handset, and a single USB data connection. There's no Ethernet socket as, although the MX320 is intended for small business, it's still designed for a single desk.
The two ink cartridges, one black and the other tri-colour, clip into the print head carrier, when you lift up the scanner section of the machine and rest it on the blue ‘bonnet support' which springs down.
