HCF media feed unit assembly operation
Upon receiving the feed start signal from the controller, the HCF activates the pick solenoid after a preset time
has passed to press the pick roll against the media in the tray.
After a preset time has passed, after receiving the feed start signal, the HCF feed lift motor rotates forward to
feed media from the tray to the feed roll side with the pick roll.
When the end of media reaches the sensor (pre-feed) and the sensor turns on, the pick solenoid is deactivated
so that the pick roll separates from the media in the tray.
The pick solenoid keeps activated at high-voltage for a specified time from its actuation. After that, it is activated
at low-voltage until it is deactivated. If the HCF receives the feed start signal for the next media while the
solenoid is activated at low-voltage, it maintains the actuation state at the low-voltage, while pressing the pick
roll 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 re-
activated for a preset time.
Media feed lift motor start/stop timing and revolutions are controlled based on the HCF feed lift motor start signal
and the sensor (pre-feed) on timing.
Thus, media is fed from the tray to the HCF media transport roll assembly.
