The expression "turn on the power" means ipping on the power switch, closing the
front door, and closing the delivery unit door, which results in supplying the machine with
power.
2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is
"High", while '0' is used to indicate "Low". (The voltage value, however, differs from
circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD
signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked

Overview
Paper inside a cassette is lifted up by the Lifter Plate.
The Lifter Plate rises by the rotation of the Cassette 2 Lifter Motor (M104). When the Pickup
Roller comes in contact with the surface of paper, paper is picked up by rotation of the
Cassette 2 pickup Motor (M102), and only a single sheet of paper is moved to the feed path
by the Cassette Feed Roller and the Cassette Separation Roller. Then, it is moved to the Pre-
registration Roller by the rotation of the Cassette 2 Pullout Motor (M106).
The Cassette 2 Pickup Roller, the Cassette 2 Feed Roller and Cassette 2 Separation Roller
are driven by the Cassette 2 Pickup Motor (M102) while the Cassette 2 Vertical Path Roller is
moved by the rotation of the Cassette 2 Pullout Motor (M106).

■Paper Size Detection Control
The paper size in the cassette is automatically detected by the "Cassette Size Switch" after
the position of the Guide Plate is adjusted and the cassette is installed in the host machine.
By shifting the Guide Plate, concavo-convex area of the Cassette Size Dial is switched
and the Cassette Size Switch at the printer side is switched. The switch consists of 3
microswitches, and the length is detected in accordance with the combination of ON/OFF.
(When the switch is pressed: ON) For standard size paper, any of AB conguration, inch
conguration, or AK conguration can be used. However, distinction between A5-R and
STMT-R should be made manually on the check screen.
Distinction between EXEC-R and 16K-R, and between LTR-R and 16K-R is automatically
made according to the country setting.
*: Whether to select A5-R or STMT-R can be registered in the user mode setting.

■Paper Level Detection Control
Paper level inside the cassette is detected by the sensors shown in the following table.
The paper level in the cassette is detected by the Cassette Lifter Motor, Cassette Paper
Sensor, Cassette Paper Surface Sensor, and Cassette Paper Level Sensor.
Cassette Paper
Sensor
OFF ON OFF* 100% to 50%*
OFF ON OFF
OFF ON ON Approx. 50 sheets or less
The control that switches the paper level display on the Control Panel is as follows:
• From 3 bars to 2 bars on the Control Panel:
The paper level is detected based on the time for which Cassette Lifter Motor is
continuously turned ON. Or, it is detected based on the time from when the Cassette Paper
Sensor is turned ON to when the Cassette Paper Surface Sensor is turned ON.
The paper level during paper feed is detected based on the number of times the Cassette
Lifter Plate is lifted up.
Related Service Mode
*: The paper level in the cassette is displayed by executing the following service mode.
You can adjust the timing of switching the scale from "3" to "2".

the level in the cassette X)
