I timed the printer on our business applications suite (using QualityLogic's hardware and software for timing) at an effective 2.5 pages per minute (ppm). The best that can be said for the MG5420's speed is that it's not sluggish enough to count as a serious problem. However, once I got past setup, everything worked well enough. I'd be a lot more comfortable with this issue if the error message had told me something useful. After I turned the printer off, then on again, the alignment page printed, and I had no other problems.

The printer refused to print the automatic alignment page the first two times I tried, showing an unhelpful error code on the front panel LCD and telling me to try again. Setup was standard, but with one annoying hiccough.

Setup and Speed I ran my tests using a USB connection to a system running Windows Vista. With no ADF, however, placing and turning over pages on the flatbed is a strictly manual task. Also very much on the plus side is a built-in duplexer (for two-sided printing), which also works for two-sided copying. One small plus is a second tray for photos only, which can hold up to 20 sheets of 4 by 6 photo paper to let you print photos without having to swap out the paper in the main tray. The 125-sheet input capacity is a bit more than the MG4220 offers, but still suitable only for light-duty use even in a home office.

You can also preview images on memory cards with the 3.0-inch color display before printing. Additional features include scanning directly to or printing from a memory card, including printing directly from a memory card to a printable optical disc. Basic MFP features are limited to printing, scanning, and copying.
