My Canon i455 has suddenly decided to not work. When I turn it on it makes a loud clicking noise instead of moving the ink tanks from one end to the other and back again. It sounds like a gear is skipping but I can't see it. I have the printer's outer shell off, and the ink tanks out, but I still can't get to the gears. Please, help me! Thank you!

SOURCE: waste ink tank full

normally, the logical solution is to replace your waste ink tank, but I have tried a solution which could make your canon printer function again.

Try this: With your printer turned ON, press and hold the I/O switch then pull off the power cord. This will turn off your printer. But without lifting your finger on the I/O switch put back your power cord. the I/O switch will blink for a second and will go off, then turn-on your printer again and see if it works.

SOURCE: HP P3005 making grinding noises

this is a problem that HP refuses to acknowledges. Its caused by the gear that meshes with the main fuser gear..it wanders to the right as the printer prints. we are checking into a fix for this, since we are getting no cooperation for the manufacturer, Canon or HP. Canon makes the print engine

I had a persistant grinding noise about 30 seconds after the printer finished printing. It's been going on about 2 months. I did one thing which seemed to work. So try opening the cover on the back of the machine by lifting upward on the gray lever in the middle of the back of the machine. Leave this cover open during and after printing. The grinding noise went away.

I had exactly the same problem with my OfficeJet 6110 as reported above (i.e. the scan head not knowing where the end-stop is). This is how to fix it (this method worked for me) 1) Lift up the scanner/copier hinged lid. Around the edge of the scan glass are 4 Torx screws. Undo all four screws. 2) Carefully prise the control panel faceplate off. The buttons underneath are on a single panel. Slide this to the left and lift off. 3) Jiggle the lid of the scanner to get it off the main body of the printer. 4) Locate the scan engine motor (top right corner) and remove the two motor retaining screws (one on the left of the motor, the other on the right). 5) Lift out the entire mechanism (rod, drive belt, scan head) and turn over. 6) Thoroughly clean all glass and mirrored areas of the scan head. Also clean the scan lamp on the top of the scan head. Clean the tray inside the scanner (where the scan head travels back and forth). Also clean the inside and outside of the scanner glass pane itself. 7) Refit all parts, using the technique described above, in reverse order. 8) Switch on printer. It should now work OK. Hope this helps, guys.
