11.3.10 Paper pick-up pressure switching mechanism
• A paper misfeed may infrequently occur, if lightweight 52 g recycled paper, or the like, is used under high temperature, high humidity
environment. (Paper pick-up pressure is too high for the thin paper)
• Replacement of the pick spring that is mounted to paper feed unit 2 may lower the paper pick-up pressure and reduce the paper misfeed.
• For the replacement procedure, see "
NOTE
▪ Since the spring is available to the recommended thin paper (CS520), replacement is not required.
▪ At using plain paper under high-temperature, high-humidity environment or feeding thick paper after replacement of the pick-up
spring, a paper misfeed may infrequently occur. (Paper pick-up pressure is too low for the thick paper)
11.3.11 Paper size detection control
(1) Paper width detection (CD)
• The size in paper width is detected with the combination of ON/OFF the transmission type photosensors 1, 2 on the CD paper size
board.
• The CD paper size sensor is unblocked or blocked according to the position of the paper width detection plate connected to the paper
width guide plate.
(2) Paper length detection (FD)
• The size in paper length is detected with the combination of ON/OFF transmission type photosensors 1 to 4 on the FD paper size board.
• The FD paper sensor is unblocked or blocked by the paper length detection plate position connected to the paper length guide plate.
• The sensor on the FD paper size board also functions to detect whether the tray is mounted.
