E078 = Error in detecting HP of ITB cleaner (Error in failure of detecting HP (pressure) of cleaner unit of transfer belt)

0001 = The HP sensor does not go on within 5 sec after the start of a HP search.
Part number for the HP sensor is FK2-0149-000

Ensure that motor M18 (FK2-0574-000) is rotating and check actuation of the HP sensor PS24.



Check the shift motor of the brush roller. Check the HP of the brush roller

ITB Cleaner Attachment/Detachment Detection
-imagePRESS C1 (Printer) / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+
This machine performs home position detection to detect the position of the brush roller for ITB cleaning.
The DC controller monitors the output of the brush roller home position sensor (PS24) via the side driver PCB to perform this detection.
At power ON or after opening/closing the front cover, the DC controller detects the position of the brush roller by checking whether the home position flag fixed on the drive shaft of the brush roller attachment/detachment motor (M18) interrupts PS24 or not.

ITB Cleaner Attachment/Detachment Control
= imagePRESS C1 (Printer) / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+
To remove the residual toner on the ITB, this machine performs attachment/detachment between the brush roller for ITB cleaning and the ITB.
The DC controller performs attachment/detachment by activating the brush roller attachment/detachment motor (M18) via the side driver PCB.
The DC controller activates the brush roller by driving the brush roller drive motor (M26) via the side driver PCB.
The following is the timing of attachment/detachment.
1. At initial rotation or just after the start of secondary transfer, the DC controller outputs the brush roller attachment/detachment drive signal via the side driver PCB.
2. The attachment/detachment arm is activated by rotating the attachment/detachment cam clockwise -
(thereby locking brush roller in place against ITB
3. After applying pressure on the ITB, the DC controller outputs the brush roller drive motor drive signal via the side driver PCB.
(The brush roller is activated)
4. The DC controller applies positive/negative bias to the bias roller, and removes the residual toner on the ITB via the brush roller.
5. After cleaning the ITB, the DC controller outputs the brush roller attachment/detachment motor drive signal via the side driver PCB.
6. The attachment/detachment arm is activated by rotating the attachment/detachment cam clockwise -
(The brush roller is separated from the ITB)
