Hello. Try removing all sheets of paper from the printer. Make sure to check in the feeder by peeking inside it. Clear any foreign objects. Open the printer cover, and remove the cartridges. Clear any foreign objects around the cartridge carrier. Close the printer cover without the cartridges. Unplug the printer from the power outlet. Plug the power back after 10-15 seconds. It should power on automatically. When printer asks for the cartridges, load them back in. Close the cover down. Printer will print an alignment page. Just let it finish print the page. When there's no more error, try to make a copy or print from the computer to check. Hope this helps.

Lexmark does not recommend the use of refilled/remanufactured cartridges. They tend to degrade print quality and printer/cartridge performance.
Note that once a cartridge is refilled, it can no longer register its ink level.

SOURCE: how to print faxes from the lexmark x5630 which is stored in the memory

Usually, faxes are temporarily sent to the printer's memory when one of the cartridges' ink level is not substantial for printing at the instance of receiving the fax. When this happens, try to replace the cartridge(s), *without navigating away from the message "fax sent to memory", by opening the printer cover and replacing the low-ink or empty cartridge(s). After the new cartridge is installed, close the printer cover and press the OK button. Your printer should then print the fax stored in the memory.
*Make sure not to navigate away from the "fax sent to memory" message, otherwise, data will be lost.

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.
