• Paper feed operations of the manual bypass tray are driven by the paper feed motor.
• The bypass pick-up solenoid is energized by a print start signal and the paper is raised to the paper feed position.
• After the paper is raised to the paper feed position, the bypass paper feed clutch is energized.
• When the bypass paper feed clutch is energized, the drive from the paper feed motor is transmitted to the manual bypass tray paper feed
roller, so that the paper can be fed in.
• The manual bypass tray paper feed roller feeds the paper onto the registration roller.
• When the paper fed from the manual bypass tray is reached onto the registration roller, the bypass paper feed clutch is deenergized to
stop the manual bypass tray paper feed roller from rotating.
• The bypass pick-up solenoid is energized and the paper is lowered to the standby position.
• If the registration sensor does not detect paper even after the lapse of a predetermined period of time, the machine determines that there
is a paper misfeed at the manual bypass tray. Note, however, that the paper feed sequence is repeated a second time if a paper misfeed
is detected. If the registration sensor is still unable to detect paper, the machine determines that there is a paper misfeed at the manual
bypass tray. (Paper feed retry control)
