G. Rear edge plate solenoid
Mark the solenoid installing position before replacement, and fix a new
one to the marked position. (The solenoid and the installing plate
positions are determined by the round hole.) 
After fixing, pull the plunger with your finger and check that the rear
edge plate rotates 90 degrees and makes contact with the rear edge
plate slide. Then release the finger and check that the rear edge plate
returns smoothly by the spring and that it is vertical to the alignment
tray after returning.
H. Paper holding solenoid
Fix the paper holding solenoid below the long fixing hole so that the
whole paper hold installing plate unit is in the lower limit of the adjust-
ment range.
(The solenoid and the installing plate positions are determined by the
round hole.)
[7] MAINTENANCE

[9] CIRCUIT DESCRIPTIONS
1.  General
The finisher main circuit sends/receives commands to/from the copier’s MCU PWB, and controls loads according to the commands and controls
input/output of sensor/switch information.
The finisher is composed of this circuit, the circuit which makes inputs from sensors and switches, the circuit which drives motors/solenoids/clutches,
ROM, RAM, and the peripheral circuits.
