The cleaning operation is activated at the following timing.
- The temperature of the fixing roller is 100 deg C or lower when the power is turned on.
- Wire cleaning is performed in the user mode.
- Every 2000 copies (2000 copies in the mono color mode, 500 copies in the full color mode) (*1)
*1: Adjust the cleaning interval for the number of copies using the following service mode.
In the normal environment: COPIER > OPTION > BODY > W-CLN-P
In the high temperature/humidity environment: COPIER > OPTION > BODY > W-CLN-PH
7.5.5 Pre-Exposure LED
0012-8172
imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+
This machine uses the pre-exposure LED to prevent uneven density in the print image by removing the remanent charge on the photosensitive drum.
The pre-exposure LED is located in the position opposed to the photosensitive drum, and LED lights up for every printing.
This removes the remanent charge on the drum surface and realizes a stable image formation.
The DC controller turns on/off the pre-exposure LED by controlling the pre-exposure LED drive signal (PRE_EXP_LED_ON) via the side driver PCB.
The following drive signal is output from the DC controller.
- When PRE_EXP_LED_ON is "0", the pre-exposure LED lights off.
- When PRE_EXP_LED_ON is "1", the pre-exposure LED lights up.

7.6 Developing Rotary
7.6.1 Overview of Developing Rotary
0013-9807
imagePRESS C1 P / imagePRESS C1
The developing rotary has a function to move the developing unit to the specified position.
4 types of developing units (Y, M, C, Bk) are stored inside the rotary.
When making prints, the developing rotary motor (M4) rotates the rotary counterclockwise. The mechanism is to make the 4-color developing units sequentially
face against the photosensitive drum.
The developing rotary motor (M4), a stepping motor, executes locking/unlocking of the rotary.
A sensor (PS21) is equipped in the rotary to detect the position of the rotary unit.
The DC controller controls these electric loads (M4, PS21).
