Canon laser class 2050P: getting alarm message: "check cover/cart" . I've opened & closed everything, tried a new toner cart, and unplugged the power..nothing has worked. Can you help?

Clean the inkhead with a wet paper towel.

Two possible solutions remove the top cover (Two screws on top after oepening the cartridge door and two push in black nylon screws in either side). and check the activation lever that activates the cover switch is not riding on top of the switch. Second if this happened your toner cartridge make sure this new cartridge is the correct one for the fax and not a HP modified recycled printer cartridge.

Hi There!
What you can do to clear the Drum Error message is to clean the corona wire.

• Open front cover of the machine and remove the drum & toner cartridge assembly.
• Remove the toner from the drum and gently shake the toner cartridge from side to side put it on a piece of paper to avoid scattering the toner.
• Theres a blue tab on the upper left side of the drum, slide it from left to right, right to left about 5-6 times don't forget to put the blue tab back to it's home position(where the arrow is).
• Put the toner back into the drum make sure it will click into place.
• Reinstall the drum and toner assembly back into the machine and close the front cover.
• LCD should display the date & time.

If you continue to receive the message try resetting the drum counter by doing the following:

• Open the front cover
• Press the Options key on the control panel. The display will show "REPLACE DRUM - 1.YES 2.NO".
• Press 1 to reset the drum count.
• Close the front cover

Hope this helps!

Your rollers will need to be replaces. Rollers feed the paper through the tray. You can find paper feed rollers for your device here:

They are very straight forward to install and instructions should be in your manual.

try a new cartridge

Either it needs toner/drum unit replaced or it's hungry for paper....is it displaying an error code?

check cover has to do with the door.
either the switch is not being activated or there is a problem with the door

there are a couple of things did you buy genuine or reman cartridges and check if they are seated properly.
some remans dont work properly so you have to be sure and always get a money back guarantee from the seller
