The LCT is equipped with a remaining paper detection gear which rotates together with LT up/ down motor (M100) driving the up/down plate.
The remaining paper detection gear has an actuator to turn ON/OFF LT remaining paper detection PS1 (PS102), LT remaining paper detection PS2 (PS103), LT remaining paper detection PS3 (PS104), and LT remaining paper detection PS4 (PS105).
*1 Paper lifting
a.Up/down plate lifting drive operation
The up/down plate is lifted with the up/down wires. When the top cover closes, LT up/down motor (M100) rotates and the up/down plate connected to the up/down wires rises.
b.Up/down plate down drive operation
The up/down plate automatically lowers by 120 mm when the top cover is opened. Subsequently, it is lowered by 120 mm each time LT tray down drive switch (SW100) is pressed.

Each sensor is turned ON/OFF according to the rotating position of the remaining paper detection gear and since this is linked with the up/down position of the up/down plate, the remaining paper quantity in the LCT can be determined by monitoring the ON/OFF of each sensor. The remaining paper quantity detected with the four sensors is displayed on the main body display.

The first paper is fed by the paper feed roller and the feed roller driven by M101(LT paper feed) via MC101(LT feed MC). The paper feed roller and feed roller touche the paper when SD100 (LT first feed) is ON, feeding the paper to the conveyance roller. Then, SD100 (LT first paper feed) turns OFF to release the paper feed roller and feed roller from the paper. The conveyance roller is also driven by M101, by turning ON MC102 (LT first feed MC), paper is fed to the main body.
The related signals are: PS100 (LT top cover open/close detection), PS106 (LT feed), PS107 (LT first feed), and PS110 (LT jam access door open/close detection).

1. Operation
a.First paper feed timing
(1) Start of first paper feed
At predefined interval after the START button is pressed.
(2) Start of second and subsequent papers
When PS106 (LT feed) is turned OFF by the preceding paper.
(3) OFF timing
When the main body M7 (paper exit) turns OFF.
b.Interlock
The power supply line of M101 (LT paper feed) is equipped with MS101 (LT interlock/1) and MS102 (LT interlock/2). When the top cover is opened, MS101 turns OFF, and when the jam access door is opened MS102 turns OFF, thereby cutting off the power supply to M101.
Furthermore, the top cover is equipped with PS100 (LT top cover open/close detection) and the jam access door is equipped with PS110 (LT jam access door open/close detection) and when either of these doors is opened during paper feed, the M101 drive signal is turned OFF to stop the paper feed operation.
c.Internal heater
The LCT is equipped with HTR101 (LT internal heater) to protect the paper from humidity. HTR101 is directly controlled by the main body PRCB (printer control board) rather than by the LTDB (LT drive board).

When the top cover opens or closes, M100 (LT up/down motor) rotates forward or backward to move the up/down plate up or down. The up/ down plate descends by 120 mm each time SW100 (LT tray down drive) is pressed while the top cover is opened.
The related signals are PS100 (LT top cover open/close detection), PS101 (LT lower limit detection), and PS109 (LT upper limit detection).
1. Operation
a. Up/down plate descend timing
(1)ON timing
When the top cover is opened and PS100 (LT top cover open/close detection) is turned OFF, M100 rotates backward to lower the up/down plate.
When SW100 (LT tray down drive) turns ON by pressing, M100 rotates backward to move the up/down plate down.
(2)OFF timing
M100 turns OFF at predefined interval after PS100 turns OFF or SW100 turns ON. This in turn lowers the up/down plate by 120 mm.
(3)Others
The up/down plate descends by 120 mm each time SW100 is pressed until PS101 turns ON to indicate the bottom limit of the up/down plate.

b. Up/down plate ascend timing
(1)ON timing
When the top cover is closed and PS100 (LT top cover open/close detection) is turned ON, M100 (LT UP/DOWN) rotates forward to raise the up/ down plate.
(2)OFF timing
When the up/down plate rises and PS109 (LT upper limit detection) turns ON to indicate the detection of the topmost paper, M100 (LT UP/ DOWN) turns OFF and stops the up/down plate. The up/down plate also stops when the top cover is opened and PS100 (LT top cover open/ close detection) turns OFF.

These signals switches the direction of the drive current to control the rotation direction of M100.
The remaining paper quantity is detected by PS102 (LT remaining paper detection 1), PS103 (LT remaining paper detection 2), PS104 (LT remaining paper detection 3), and PS105 (LT remaining paper detection 4) and no paper detection is made by PS108 (LT no paper detection).
The signals detected by these sensors are controlled by LTDB (LT drive board) and displayed on the main body display.
1. Operation
a.Remaining paper detection control
The remaining paper quantity is determined from the ON/OFF combination of sensors PS102 (LT remaining paper detection 1), PS103 (LT remaining paper detection 2), PS104 (LT remaining paper detection 3), and PS105 (LT remaining paper detection 4) which detect the rotational position of M100 (LT UP/DOWN) that is driving the up/down plate. Each sensor turns ON or OFF according to the position of the remaining paper detection gear which is linked with the rotation of M100.
The remaining paper quantity is detectable at eight levels, but it is displayed on the main body display as five levels.
