imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+
This machine performs attachment/detachment between the secondary transfer outside roller and the ITB to transfer the toner on the ITB to the print paper.
The DC controller activates the secondary transfer outside roller attachment/detachment motor (M17) via the feeding driver PCB to perform attachment/detachment.
The following is the timing of attachment/detachment.
1. After completing primary transfer, the DC controller outputs the secondary transfer outside roller attachment/detachment motor drive signal.
2. The clockwise rotation of the attachment/detachment cam pushes the attachment/detachment plate, and pushes the attachment/detachment arm down.
(thereby locking the secondary transfer outside roller in place against the ITB)
3. After completing secondary transfer, the DC controller outputs the secondary transfer outside roller attachment/detachment motor drive signal.
4. The clockwise rotation of the attachment/detachment cam releases the attachment/detachment plate, pushes down the attachment/detachment arm.
(thereby locking the secondary transfer outside roller in place against the ITB)
This operation is performed also at initial rotation and cleaning the secondary transfer outside roller.
