the solenoid is activated at low-voltage, it maintains the actuation state at the low voltage, while pressing the
pick roller against the media in the tray.
When the media is transferred to the printer and the sensor (tray 5 feed-out) turns on, the pick solenoid is
reactivated for a preset time.
Media feed lift motor start/stop timing and revolutions are controlled based on the timing of the HCF feed lift
motor start signal and the sensor (pre-feed).
Thus, media is fed from the tray to the HCF media transport roll assembly.
HCF media transport roll assembly operation
Upon receiving the feed start signal from the controller the HCF activates the HCF transport motor at a high
speed after a preset time has passed. This rotating power of the HCF transport motor is transmitted to the HCF
media transport roll assembly, and the media from the HCF media feed unit assembly is transferred to the
printer.
When the sensor (tray 5 feed-out) is turned on by the media fed with the HCF media transport roll assembly, the
HCF transport motor speed decreases after a preset time has passed.
When the sensor (registration) in the printer is turned on by the media fed from the HCF, the HCF transport
motor turns off.
When the next feed start signal is received, before the HCF transport motor is turned off, the transport motor
continues to rotate.
