Check procedures/corrective measures
Check for continuity across the coil. If none, replace the desk
upper lift motor.
Reinsert the connector. Also check for continuity within the
connector cable. If none, repair or replace the cable.
Check if 24 V DC is output across CN2-5 (–) and CN2-6 (+) on
the desk main PCB right after the desk upper drawer is
installed. If not, replace the desk main PCB.
Check for continuity across the coil. If none, replace the desk
lower lift motor.
Reinsert the connector. Also check for continuity within the
connector cable. If none, repair or replace the cable.
Check if 24 V DC is output across CN2-3 (–) and CN2-4 (+) on
the desk main PCB right after the desk lower drawer is
installed. If not, replace the desk main PCB.
Reinsert the connector. Also check for continuity within the
connector cable. If none, repair or replace the cable.
Reinsert the connector. Also check for continuity within the
connector cable. If none, repair or replace the cable.
Check if CN3-7 on the desk main PCB goes low when the desk
upper paper length switch is turned on. If not, replace the desk
upper paper length switch.
Check for continuity between CN3-9 and CN3-1, CN3-2, and
CN3-3 on the desk main PCB. If the continuity is unaffected by
movement of the width guides in the upper drawer (i.e. either
remains present or remains absent), then replace the desk
upper paper width switch.
Reinsert the connector. Also check for continuity within the
connector cable. If none, repair or replace the cable.
Reinsert the connector. Also check for continuity within the
connector cable. If none, repair or replace the cable.
Check if CN3-8 on the desk main PCB goes low when the desk
lower paper length switch is turned on. If not, replace the desk
lower paper length switch.
Check for continuity between CN3-10 and CN3-4, CN3-5, and
CN3-6 on the desk main PCB. If the continuity is unaffected by
movement of the width guides in the lower drawer (i.e. either
remains present or remains absent), then replace the desk
lower paper width switch.
