Canon PC-920 Black and White Copier E2 error - Questions ...
www.fixya.com > ... > Canon > Canon PC-920 Black and White Copier .. error code e7 & e2 Cannon pixma mp145 printer error code e7 & e2 E2: Reload the paper correctly and press [Black] or [Color]. E7: The cartridges are not ..
On your Canon PC 920, there is a recessed gray latch located on the left side of the machine towards the top front...press upwards on this latch to release the top part of copier (same as removing a misfeed or clearing a paper jam). The copier opens up.....now, located in the top unit, about center, is the drum / toner unit. It has a black plastic handle on it. Grasp this handle and pull towards you...slowly...until it is free of machine (support the rear of the unit with your other hand) Open new cartridge (unit) and install in reverse order (there should be instructions with the new cartridge) The copier has rails that the cartridge mounts on. Another note, before installing....gently shift the cartridge from side to side.....this distributes the toner evenly (again, covered in the installation instructions packed with the cartridge) There is a tab that needs to be removed to allow the toner to get where it needs to go for copying....attatched to this tab is a strip of plastic, pull all the way out. I have a PC 940...it uses the same cartridge.
the noise could be the heat rollers have squared of this happens if the machine hasnt been used for a while the pressure makes a flat on the soft roller.. it cold also be the toner cartridge has settled. take it out and give it a good shake.. if you cansee if the scanner lamp and carriadge is moving when you run the copier up it mighht be saveable.. make sure the paper is new and dry as this can cause jams in hot section.. if you can see where the paper jam is when you do one copy check the guides as well and finally take the paper tray out and look at the condition of the rollers that feed the paper as they may be dirty and sliping the paper..Good Luck A
there are 3 reason if the copy gray & less sharp:
1) the toner you are using is not compatible very well with the cartridge unit if you changed other compatible toner.
2) the cartridge going near the life-cycle, (also cause print blurred)
3) the photo drum going near the life-cycle
you may try to change the quality toner (original factory). or
change the cartridge if it is out of the life-cycle
two options two be checked
1)this happens if the cartridges are at the end of the ink.for this cartridge replacement is required.
2)if the head in which cartridges r installed this happens.for this the head needs manual cleaning internally.
