The cover has been probably opened too widely and the the lever on the cover open sensor is knocked off the switch assembly. If you teer off the cover, you will see a little plastic lid on the right (where electric cables and switches are) This switch has come out its switch. With some fiddling around you should be able to put it back in place.

I changed my ink and now it says cover open when its not and nothing will work now


The problem could be due to a communication failure between one of the printheads (cartridges) and the All-In One (AIO) or by a short in one if the printheads. Please follow the steps below to identify and fix cartridge issues:

  1. Make sure the printer is on.
  2. Open the printer cover. The print cartridge carrier moves and stops at the loading position, unless the All-In-One is busy. Note: If the carrier does not automatically move to the center, turn off the printer or unplug the printer from the power source and then carefully slide the carrier to the center.
  3. Remove both cartridges from the carrier.
  4. Close the printer cover.
  5. Re-brick your printer by pulling out the power supply - black box behind the printer where the power cord is plugged in to, and re-plug after 30 seconds.
  6. When the printer turns on, reinsert one cartridge first. Close the printer cover and check for any errors.
  7. If no error appears, reinsert the other cartridge. Close the printer cover.
  8. Replace whichever cartridge is causing the error to appear with a new genuine Lexmark cartridge. Try to print a document again to verify that the problem is fixed.

It says i have a automatic alignment problem it shows i have ink i have'nt changed the ink since i brought the printer.


It could be that the cartridges are not seated properly in the cartridge carrier or the encoder strip got unseated from its position. Please follow steps below to fix the problem:
  1. Open the printer cover.
  2. Remove both cartridges from the printer.
  3. While the printer cover is open, check the cartridge area for a loose encoder strip (transparent strip).
  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, re-insert one cartridge first.
  7. Close printer and check for any errors.
  8. If no error appears, reinsert your other cartridge.
  9. Replace whichever cartridge is causing the error to appear with a new cartridge.

Hello my printer wont work, the powerbutton is blinking and i hear a tikking noise. is mij printer broken?? lexmark x5250


It could an alignment problem, a paper jam, or something blocking the paper path. Open the printer cover and remove both the cartridges. While the cover is open, check the cartridge area for any obstructions in the cartridge carrier's path. Check any transparent strip(encoder strip) that has become loose from its position. If there's nothing out of the ordinary, close the cover. Unplug and replug the printer into the power source to reset it. When the printer turns on, reinsert both cartridges and make sure they properly inserted and secured. Close the cover and try to print again.

HOW DO I FIX THE ERROR 004-332...???


1. Reseat and clean the 4 toner cartridges and verify the orange plastic covers have been removed.
2. Reseat the toner cartridge carousel position. By doing the following:
Lift the handle of the first available toner cartridge or toner cartridge attempting to be installed and remove the toner cartridge.
Close the front cover. Power off the printer. Power on the printer.
An LCD message Insert <toner color> Toner appears. Open the front cover. To reinstall the toner cartridge, align the arrows on the cartridge with the corresponding arrows on the printer, guide the cartridge in until it snaps into place, and then push down the right lever to lock the cartridge in place. Close the front cover. The toner cartridge carousel rotates to the correct toner position.
3. Verify the developer rotor frame is not bent. If it is bent then the printer should be replaced, it would not be cost effective to replace the frame.
4. If it is not bent. Open the front door, try to rotate the carosel. It should NOT rotate. If the rotation is rigid and feels broken, then the printer should be replaced. If it rotates smoothly, the developer latch should be replaced. If the carosel does not rotate but still gives the error the rotor control board should be replaced.

Printer says inner cover 1 is open, but it is not open,


Usually a piece of plastic from the cover turn a switch on and off. Maybe is this bit broken.
if not, unplug the printer for several hours,
take off paper and cartridge and choke the printer a little bit maybe is the switch stuck due to spread ink or dust or something else.
If still stuck, open it and find those switch, try to play with it power on. Nothing happen? change the printer ...:(

Magenta cartridge empty


When you take the toner cartridge off the imaging unit, is there magenta toner in the open slot of the IU? Assuming that there is nothing wrong with the toner cartridge, you are possibly looking at a bad engine control board.

The printer apear to be dead!


Buttons and lights on the printer Two buttons and three lights are located on the front of an HP Deskjet printer.
  • The lights tell when the printer is working or when it needs attention.
  • The buttons help control the printer.
Buttons and lights Purpose c00123886.jpg POWER button and light Push the POWER button to turn the printer off and on. When lit, the light shows that the printer is turned on. c00123889.jpg RESUME button and light The light blinks when there is a problem with paper. When the problem is corrected, press the button. c00123892.jpg Print cartridge light The light blinks when there is a problem with a print cartridge. When the problem is corrected and the top cover is closed, the light will stop blinking. Troubleshooting blinking printer lights Blinking lights Reason c00123895.jpg

All lights are off. The printer is off (asleep).

Press the POWER buttonc00123886.jpg to turn the printer on.

The printer should turn on automatically when a print job is sent to it. c00123898.jpg

The POWER (top) light is on. The printer is idle.

The printer is ready to print a document. c00123900.jpg

The POWER (top) light is blinking. The printer is busy printing.

Allow enough time to print. When a document has many fonts or graphics or uses complex color such as a color photo, it takes longer to begin printing. c00123902.jpg

The PRINT CARTRIDGE (bottom) light is blinking. Possible causes:

  • The front cover is open. Make sure the front cover is completely closed.
  • The print cartridge is missing. Make sure the print cartridge has been installed correctly.
  • The print cartridge is broken or incompatible. Lift the front cover, and wait for the print-cartridge cradle to slide out. Check the part numbers on the print cartridge:


Black: 51645A

Color: C1823D,

If the print cartridges are compatible and correctly installed, they may be defective. Try replacing the print cartridges.

If none of the above suggestions fix the problem, and, if the error message still occurs, it may be a hardware failure. Call the HP Customer Support Center.
