4026-0XX Paper Take-Up Solenoid Service Check FRU 1 Solenoid Action 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 operation and that the solenoid spring is not broken, loose, or stretched. Replace parts as neccessary. 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 solenoid 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 assembly. 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. 2-32

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.
