The Canon Pixma MX420 Wireless Office All-in-One was announced back in January during International CES 2011. It was unveiled alongside four other small office, home office (SOHO) Pixma All-in-One printers; the Canon Pixma MX882 being the frontrunner for Canon out of the bunch, which we reviewed at the end of February.

Although, we mention in the review that the Pixma MX420 is a slight step down from the MX882 in features, this wireless 4-in-1 still has much to offer at a good budget price. The MX420 has many useful office features including print, fax, copy, and scan capabilities as well as a built-in memory card reader with a front side USB port and is Energy Star certified.

Our review will include an in-depth look at all of the capabilities, specifications, the ease of use, and the build and design of the device. We will also take a look at how the MX420 and its included ink cartridges stood up against our tests in terms of print quality, print speed and more.

The Canon PIXMA MX420 inkjet has a black glossy finish and stands at about 18 x 16 x 8 inches when the trays are not extended for use.  Its compact build and design slightly mimics the somewhat higher-end Pixma MX882 with a different outer interface. It weighs just over 19 lbs in total and can fit comfortably on medium-to-large sized desks and work places if need be.

The 30-page automatic document feeder (ADF) is easy to spot on the top; to access it, you simply fold it outward. The maximum paper size for the ADF is 8.5 x 14 inches, and it will feed the documents one after another, in order to scan, copy and fax larger jobs easily. The main feeder is located in the rear, with 100 sheets being its maximum hold capacity.

The control panel spans the length of the flatbed scanner. From the left to the right, the panel includes a 2.5-inch LCD, the main controls, a four-directional pad, a number pad, facsimile controls, the black and color start buttons and a stop button. 

For regular scan jobs with manual feed, the flatbed scanner with a 48-bit color depth is found after the heavier lid is lifted from the top opening. The scanner can fit documents up to 8 x 5 x 11.7 inches in size. The scanner features Canon’s auto scan mode, push scan, network scan and scan to memory capabilities. The MX420 has many ports so the scanned documents can be saved onto your USB thumb drive, PC or memory card device. All the compatible storage devices are listed near the end of this section.

If you open the printer underneath the flatbed scanner and output tray you’ll find the inside of the MX420, where the print head is located and the cartridges can be loaded. The Pixma MX420 uses a dual-ink system with one Canon Color CL-211 dye-based ink cartridge and one Canon Black PG-210 pigment-based ink cartridge. Canon also offers high-capacity ink cartridges: the PG-210XL and the CL-211XL ink cartridges. Ink pricing details are at the end of the review.

Open the small door on the bottom-right corner of the front of the MX420 and you’ll find the built-in memory card reader. Below those ports, underneath the door, are the USB and PictBridge port. The media compatible with this inkjet include: SD, SDHC, MultiMediaCard and MultiMediaCard Plus, miniSD Card, miniSDHC Card, microSD Card, microSDHC Card, RS-MMC, CompactFlash Card, Microdrive, Memory Stick, Memory Stick PRO/Duo/PRO Duo/Micro, xD-Picture Card.

The 100-sheet tray is located in the rear, folding out from the back. It is compatible with 4×6-inch, 5×7-inch, 8×10-inch, letter, legal and U.S. #10 envelope sizes. It supports plain paper, a variety of glossy paper and is also compatible with Canon matte photo paper.

The connection slots are all located on the back of the inkjet. The MX420 can be connected for use via Wi-Fi, Hi-Speed USB 2.0, or Ethernet cable. The fan is also located in the back. Included with the MX420 is a telephone cable for the fax, power cord, set-up CD with the Canon software and drivers, and manuals (and two ink cartridges as mentioned previously). USB connection cable is not provided.
