Registration Roller Control
■ The Registration Sensor (PC1) detects whether or not the paper has reached the
Conveyance Section.
■ Conveyance of paper is restarted by synchronizing the paper conveyed with the image.
■ Since the Conveyance Roller and Registration Roller are synchronized with each other, no
loop is formed in the paper at the Registration Roller.
OHP Film Detection
To ensure that the correct paper type is being used, the OHP Sensor (PC2A) detects the
presence of OHP or paper. When the Registration Sensor (PC1) is activated, the OHP Sensor
(PC2A) is also activated and the type of paper being conveyed is determined if it is OHP film
or any type other than OHP. If the OHP Sensor (PC2A) is not deactivated, the machine
determines that the paper is a type other than OHP film. If the OHP Sensor (PC2A) is
activated, the machine determines that the paper is OHP film. If the paper type specified by the
