Thus, media is transferred from the HCF media transport roll assembly to the laser printer.
HCF media feed unit assembly sensor/motor functions
Functions of the sensors and motors of the media feed unit assembly are outlined below.
•
HCF media feed lift motor
—is a stepping motor that rotates (forward) the pick roller and feed roller to
send media from the tray to the HCF media transport roll assembly. The motor also lifts the tray by reverse
rotation.
•
HCF pick solenoid
—Raises or lowers the pick roller. The HCF pick solenoid stays activated from the
beginning of media feed until the sensor (pre-feed) turns on. The HCF pick solenoid is activated when the
tray is inserted and when the power is turned on to check the presence of media in the tray.
•
Sensor (pre-feed)
—Detects whether media has been fed from the tray, and controls the HCF feed lift
motor speed. The sensor also becomes a trigger to deactivate the HCF pick solenoid. The sensor turns on
upon detecting media, and determines that media is present.
•
HCF transport motor
—is a stepping motor that rotates the HCF media transport roll assembly to feed
media to the printer.
•
Sensor (tray 5 feed-out)
—Detects whether media has been fed from the tray, becomes a trigger to stop
the HCF feed lift motor, and controls the HCF transport motor speed.
