Question about Lexmark X3470 All-In-One InkJet Printer

4 Answers

COVER OPEN I just replaced the ink cartridge on my lexmark x3470. The screen displays "cover open". I have opened and closed the cover a few times to try to fix this problem. I have unpluged the power pack and waited for about 15 seconds. It still does the same thing.

There is a plastic lever in the back of the scanner where it comes into contact with a part made to push the lever when closed to work the switch. It is a poor design. The lever fits over the small micro-switch very loosly and the tabs wear out really quick. Lexmark will not send another lever. They state buy another printer. If you are real careful, you can put the lever back on the switch and hold it in place while you close the lid.

It could be that the cover sensor is stuck or could also be due to the cartridges in the printer. Please follow the steps below on how to identify and fix the problem:
  1. Remove the sheets of paper from the feeder.
  2. Open the printer cover and remove the cartridges.
  3. Close the printer cover.
  4. Re-brick your printer by pulling out power supply, black box where the power cord is plugged in at the back of the printer, and put it back after 30 seconds.
  5. When the printer turns on, reinsert one cartridge first.
  6. Close the printer cover and check for any errors.
  7. Reinsert the other cartridge.
  8. Replace whichever cartridge is causing the error to appear.
  9. If no error appears, reload some sheets of paper and try to print a document again to verify that problem is fixed.
If the problem continues, please contact the Lexmark Technical Support Center for additional assistance.

Lexmark x3470 printer says "cover open" and it will not do anything. Curtis

Try these as I found them from Lexmark's website

Solution What you will see
The printer displays a 'Cover open, please close cover' error message, even though the cover is closed.
Possible cause of the error
This can happen if the lever on the cover open sensor is knocked off the switch assembly.
What to do
Take the following steps to try to determine if there is a hardware fault:
Steps Actions 1 Remove and replace the cartridges from the printer. 2 Disconnect the power cable and the USB cable. 3 Check that the power cable is plugged directly into a wall socket. 4 Reconnect the power cable. 5 Close the printer cover. 6 If the error persists, please contact Lexmark Technical Support for further instructions.

Try looking around the edges of the cover or in the hinge area for a switch that may be stuck. Most covers have a switch to indicate that the cover is open, the cover may not be seated properly or the switch may be stuck in the open position.

Cover open is on display

put your finger on the second hole on the top from the right and press the switch (it's small, gotta try a little...), when the display changes, press copy and close the door... it just worked for me!!
