Paper Take-Up Solenoid Service Check
FRU Action
1 Solenoid Be sure the solenoid/engine board cable is
firmly seated in connector CN3 on the engine
board.
Be sure the solenoid cable is firmly seated in the
solenoid/engine board cable connector at the
solenoid.
Check the solenoid for proper mechanical oper-
ation and that the solenoid spring is not broken,
loose, or stretched. Replace parts as necces-
sary.
Be sure the solenoid to paper lift plate ground
strap is installed correctly.
Disconnect the solenoid cable from CN3 on the
engine board. Check the resistance of the sole-
noid between CN3-5 and CN3-6 on the cable.
The resistance should measure between 60 to
90 ohms.
Check the continuity of the solenoid/engine
board cable. If the cable continuity is correct,
replace the solenoid. If the cable continuity is
incorrect, replace the paper feed frame assem-
bly.
Disconnect the solenoid from the solenoid/
engine board cable at the solenoid and check
the resistance between each pin on the solenoid
connector and the solenoid frame. If continuity is
indicated, replace the solenoid assembly.
