Corrective measures
Change the paper.
Check visually and replace any deformed pulleys.
Check visually and replace feed switch 3 if the actuator is broken.
Run maintenance item U031 and turn feed switch 3 on and off manually. Replace feed switch 3 if indication of the corresponding switch on the operation panel is not displayed in reverse.
Run maintenance item U247 and select the desk upper paper feed clutch on the operation panel to be turned on and off. Check the status and remedy if necessary.
Check (see page 1-3-7).
Change the paper.
Check visually and replace any deformed pulleys.
Check visually and replace the desk feed switch if the actuator is broken.
With 5 V DC present at CN2-8 on the desk main PCB, check if CN2-7 on the desk main PCB goes low when the desk feed switch is turned on. If not, replace the desk feed switch.
Run maintenance item U247 and select the desk lower paper feed clutch on the operation panel to be turned on and off. Check the status and remedy if necessary.
Check (see page 1-3-7).
Check visually and replace feed switch 2 if the actuator is broken.
Run maintenance item U031 and turn feed switch 2 on and off manually. Replace feed switch 2 if indication of the corresponding switch on the operation panel is not displayed in reverse.
