imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+
This machine performs home position detection to detect the position of the secondary transfer outside roller.
The DC controller monitors the output of the secondary transfer outside roller home position sensor (PS23) to perform this detection.
At power ON or opening/closing the front cover, the DC controller detects the position of the secondary transfer outside roller by checking whether the home po-
sition flag fixed with the M17 drive shaft interrupts PS23 or not.
