Question about Canon Office Equipment & Supplies
Look for a thin mylar strip running behind the printheads which should be sitting in a little guide tab, but has probably fallen out. Put the mylar strip back in place. Recommended by Canon support, one poster reports permanent resolution of the problem. The Canon tech said he gets about three calls a week for this problem.

This particular error had stumped me for a while, but I finally found the cause. As others had pointed out before, it can have alot to do with some obstruction in the print path, the gears, or ink on the clear plastic encoder strip. You're on the right track - I found the the purge cap (the white sliding mechanism that the print head parks to when it's not in use) was not lubricated well enough from factory. If you lubricate the sliders with some white grease (don't get it on the small wipers or the black caps) the mechanism can now slide more freely, and the unit can park the head properly without giving you the dreaded head homing error 5100 (or E-2-2 on the LCD display) Keep in mind that this repair will probably require you to remove the right panel off of the printer to gain access to the purge mechanism. There are two screws behind the printer, and two in front for each corrosponding side panel (the front screws are behind the grey front panel of the printer - open the top cover to see the clips which hold the front cover on) Hope this helps some of you out.

Open up the hood, slide the ink cartridges to the far left, and check for a small silver piece that has dislodged from the far right side of the interior. You will probably need a flashlight to see. It is about the size of a folded paperclip. Even if it is still in place, remove it anyways because the printer identifies it as an obstruction. It serves no purpose so do not feel apprehensive about doing this, it will fix this problem.

The scanner lock switch may be in the locked position. Lift the cover and check the slide switch located on the top front left. If this is not the problem, you will have to have a service center look at the problem.
