If the HCF media tray is not lifted, the media out actuator remains in the sensing area of the sensor (media out),
while blocking the light transmission of the sensor (media out). Media out is detected regardless of the presence
of media in the tray.
Detection of media out is carried out constantly after the lifting operation is completed.
When media out is detected, media transfer from the HCF is inhibited.
If media out is detected during printing, print operation of the next media is stopped. However, when the printer
is operating in the Auto Tray Select mode and there is media of the same size in another tray, media is
automatically fed out of the tray.
Sensor (media out)
Detects whether media is present in the HCF media tray.
When this sensor (media out) is off while the tray is at the feeding position, the presence of media is detected.
Remaining media volume detection
This function determines the media volume remaining in the HCF media tray by using the HCF feed lift motor
rotation time and the sensor (media level) during the tray lifting time. The printer notifies operators of remaining
media volume as 25%, 50%, 75%, full, or 0 (zero).
If the remaining media volume becomes zero before no media is detected, the indication remains at (25%).
When the sensor (media level) detects no media, the indication becomes (0) (zero).
When a fault occurs, determination of remaining media volume is carried out as shown below.
•
When the interlock is opening during the lifting operation, the remaining media volume is determined
based on the total of the time it takes for the interlock to open, plus the amount of time that transpires from
the media feed lift motor forward/reverse rotation until the sensor comes on.
• When the power is turned off and on during the lifting operation, the remaining media volume is determined
by the lifting time after the power comes on. (The actual volume of media in the tray may differ from the
indication.)
