Paper picks during POST and/or continuously

FRU	Action
Paper feed assembly Paper feed solenoid	Check the pick mechanism for wear. The solenoid releases the shaft of the D-roll, allowing it to engage with a gear on the main drive. There is a step in the plastic part of the shaft that rests against the solenoid arm. This error occurs if the step is worn or damaged so the solenoid cannot stop the rotation. Replace the paper feed assembly if necessary. Make sure the spring on the solenoid is properly installed. If the spring is improperly installed or missing, the pick roller will continuously pick paper. Replace the solenoid as necessary.

Paper picks but stops half way through the printer

FRU	Action
Input paper feed sensor Controller card assembly	Make sure the input paper feed sensor is working properly. heck for a broken or stuck flag on the input paper feed sensor. Make sure the cable is seated on the controller card assembly (J20). Verify +5 V dc on pins #1, #4, #7, and ground on pins #3, #6, and #9. See “Locations and connections” on page 5-1 for more information. If correct, replace the input paper feed sensor. If the voltage is not correct, replace the controller card assembly. Note: Always check printhead alignment after replacing the controller card assembly. See “Printhead assembly adjustment” on page 4-2 for hardware alignment of the printhead.

Paper never picks

FRU	Action
Paper tray	Make sure the paper tray and paper are correctly positioned. Check the input tray for missing or broken parts. Replace the tray as necessary.
Paper feed solenoid Controller card assembly	Make sure solenoid is installed correctly and its cable is plugged into the controller card assembly at J15. See “Locations and connections” on page 5-1 for more information. Verify approximately 55 ohms in the solenoid. If not correct, replace the solenoid. Verify the solenoid has the spring in place and functions mechanically. If this is true and the resistance is correct, replace the controller card assembly. Note: Always check printhead alignment after replacing the controller card assembly. See “Printhead assembly adjustment” on page 4-2 for hardware alignment of the printhead.
