A general error message asking you to open the cover over the glass (usually) and check for something in the paper path or on the glass. This message is usually covered in the user manual for the printer. Make sure the cover is completely back down and/or latched before hitting the print button.

Check printer cover mesage

Open that cover and close it using some force is quick and the costumer can do it also.
The perfect solution for a technician:

The machine detects the opening of the lower door on the left side (under the manual tray) as a cover open. There is one sensor for paper jam and cover open. If the lower right door is open, the photointerruptor is free. If you close the right lower inner door, it is blocked, and when it is closed, and there is a paper in this section the sensor is free. Sometimes the edge of lower inner door doesn't makes the sensor moving, insted of crushes up. Then a little amount of grease can help you.

Message says COVER OPEN CLOSE COVER but the cover is closed

The problem could be due to the printer cover sensor getting stuck or the cartridges in the carrier. Please follow steps below to identify and fix the problem:

1. Remove the sheets of paper from the feeder. Make sure there are no foreign objects or debris in the feeder.

2. Open the printer cover and remove both the cartridges.

3. While the cover is open, ensure there are no paper jams and the cartridge carrier is free from obstructions.

4. Close the printer cover.

5. Unplug and re-plug the printer into the power source to reset it.

6. When the printer turns on, reinsert one cartridge first.

7. Close the printer cover and check for errors.

8. If no error appearsl, open the printer cover and reinsert the other cartridge. Check for errors.

9. Replace whichever cartridge is causing the error to appear with a new cartridge. You can also try to insert a different known working cartridge to determine if the other is faulty.

10. Load some paper. Try to print again.

If the problem continues, please contact Lexmark Technical Support Center for additional assistance.

Open the top cover and insert a toner cartridge. message shows when i try to print but top cover already closed properly

check on the left hand side of where the top cover opens , in the inside there is a clip along with a senor
check that it si not stuck . if that doesn't work, open the top cover hold in the cancel button or the bigger play button ( differs printer to printer ) or both for approx 10 - 20 seconds , you will see all the lights flash remove the toner , re-insert the toner & close the top cover .

Alternativly switch the printer off ( with top cover closed ) hold in one or both buttons and turn it on for approx 10 - 20 seconds again , you will again see all the lights flash, Your printer will reset its status And clear its page count .
also try open the back cover close the front then the back , press cancel or play button twice there after.

Close printer cover error when cover is closed

The cover sensor might have dislodged or not in its proper position. You could try to reset your printer to determine if there's a hardware fault. Remove the cartridges from your printer. Close the cover. Unplug and replug your printer into the power source. When the printer turns on completely, reinsert your cartridges. Check if error appears again. (Error: 'Cover open, please close the cover')

Where is the Printer Cover on the Canon Fax 8500? The fax is asking to Check the Printer Cover.

The printer cover is the cover that you open to remove the cartridge. Open it and check that the cartridge is inserted correctly. Remove and reinsert cartridge then close the cover. Check all around the m/c to make sure all doors are closed.

Message on brother MFC7420 "back door open" when it's not

Actually, you need to double check the back cover and front cover, open them all to check all paper jam.
Besure to check the back cover, normally all paper jam is from the back.
be sure to close the front cover at the last cover to close.

cover "B" should be on the back of the printer. when you open the main back door at the bottom there is a little flap that will fall down, this is a sliht design flaw as you have to make sure that this is in an upright position before closing the main back door. from past experience its usualy hit and miss at getting it to work unfortunatly

hope this hepls
