The "Check Print Cartridge" light

This happens regularly in some models when the alignment of paper is not done correctly. If the cartridge does not have a good print quality, the scanner can not correctly read the alignment and alignment repeated several times until you get it right.
Check the alignment with cartridges in excellent condition.

ATTENTION light(triangle): Indicates that the print-cartridge door is open, print cartridge is missing, and other errors.

If ATTENTION and READY light is blinking:

Printer initialization
The printer is initializing.
No action is necessary.

Cleaning mode
A cleaning page is printing.
Wait until the cleaning page has finished and the printer is in the Ready state.
This could take up to two minutes.

If ATTENTION and READY light is on:

Fatal error
Turn off the printer, and then unplug the printer power cord for 30 minutes.
Plug the printer power cord into the power outlet, and then turn the printer on.
If the error persists, replace the printer.

If ATTENTION light is blinking and READY light is off:

1. Attention: door open, no print cartridge, or media jam
   

The printer is in an error state that requires operator intervention.
Check the following:
? The print cartridge door must be completely closed.
? The print cartridge is correctly installed.
? There is no media jam.

2. Out of memoryThe printer is out of memory.
The page you are printing might be too complex for the printer's memory capacity.
Try lowering the resolution.

Checking the print cartridge
Image-formation defects are frequently the result of problems in the print cartridge. If the source of the defect is not immediately evident, always replace the print cartridge before troubleshooting image defects.
Use the following checklist to make sure that the print cartridge is still operable.
? Make sure that the print cartridge is seated properly.
? Check the print cartridge to see if it has been disassembled or refilled.
? Inspect the print cartridge to see if toner is leaking through worn seals.
? Check the surface of the photosensitive drum in the cartridge to see if it has been damaged or
scratched. Touching the drum contaminates the photosensitive surface and can cause spotting
and image defects.
? Blurred areas on printed pages indicate that the photosensitive drum in the cartridge has been
overexposed to light. Because overexposure to light causes permanent damage to the photosensitive drum, the cartridge should be replaced.
To redistribute the toner in the print cartridge
Before installing a new print cartridge or when the toner begins to run low, redistribute the toner by
rotating the cartridge back and forth five or six times.

Check in "printer properties" that paper supply is set for correct type (ie A4 not Letter) ?
