• Remaining paper detection is made by the remaining paper VR/1 (VR2) and /2 (VR4) that are interlocked
with the up/down operation of the paper lift plate via the pulley and the gear.
• The following 8 levels are detected according to the resistance value, and the detected information is sent
to the main body.

Tray lock control

• Each of the tray is locked by the tray locked lever.
• When the tray lock release sensors /1 (PS4) and /2 (PS12) of the either trays /4 or /5 are turned off, the tray
lock solenoids /1 (SD4) and /2 (SD8) of the corresponding tray are turned on. This causes the tray lock lever
to go up and the tray is unlocked.
• In order to avoid pulling multiple trays out at a time, the SD4 and SD8 solenoids other than those which has
already been turned on do not become on even when an off-status of another lock release sensor is
detected while PS4 or PS12 sensor is off.
• When a jammed paper is lying over the tray and the exit conveyance section, the tray remains locked until
the jammed paper is removed. This prevents the paper from being torn off.
