Trimmer board control

A. Mechanism
The trimmer operation may be conducted improperly due to the damage on the trimmer board if the trimmer
board is subjected to the trimmer blade many times at the same position. For this reason, the trimmer board is
slid 1 mm backward for sheet cutting each time a job of 700 times trimming is completed.
The trimmer board solenoid (SD11) [1] slides the trimmer board [5] with its fixing released by the trimmer press
motor (M32).
The pinion [3] pushes the rack [4] 0.5 mm every time SD11 turns ON. The rotation of the pinion is transmitted to
the rack by the one-way clutch [6] and pushes the trimmer board when SD11 turns ON. The pinion does not
rotate and push the trimmer board when SD11 turns OFF by the one-way clutch.
Each time a job of 700 times trimming is completed, SD11 is turned on twice to move the trimmer board 1 mm.
The trimmer board can be slid up to approximately 26 mm. The main body displays the message on its opera-
tion panel when the trimmer board replacement sensor (PS59) [2] turns ON. The trimmer operation is prohibited
when the trimming is conducted 700 times since PS59 turns ON.
Note
• For C6500, the operation timing of the trimmer board solenoid can be selected among 700/500/300
(700 by default), and the travel distance can be selected among 1.0/1.5/2.0 mm (1.0 by default)
from "Finisher adjustment" in service mode.
• For 1050, if the DIPSW22-5 setting in service mode is changed to 1, the operation timing of the
trimmer board solenoid becomes selectable among 700/500/300 (700 by default) on the adjust-
ment screen in the user mode.
• The barr may occur on the trimmed edge of the paper before the movement cycle of the trimmer
board depending on the paper type.
