A grinding sound is heard when the printer is turned on or when it is printing. Blinking lights may accompany the noise. The problem can be caused by a carriage stall or a paper jam.
Turn the printer on.
For the 800, 900, 3820, 5500, and 6000 series, open the top cover of the printer. Verify that the carriage moves to the centre of the printer. If the carriage does not move to the centre, proceed to step 2.
For the 5100, 5600, and 5800 series printers, open the top cover of the printer. Verify that the service station (the piece below the cartridges) lowers, allowing access to the cartridges. If the service station does not lower, proceed to step 2.
Unplug the power cable from the back of the printer.
If the carriage moved to the center, or if the service station lowered, remove the cartridges. Check inside the printer for any broken parts.
If the carriage did not move to the center, try to manually slide the carriage to the center. If the carriage is locked either in the left or right position, proceed to step 5.
