The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and
mechanical systems with reference to the timing of operation.
In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, the arrow
indicates the direction of the electric signal.
The expression "turn on the power" means flipping 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 in the field. Therefore, the operations
of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of
the DC controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and
major changes will be communicated in the form of Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service
Information bulletins and be able to identify and isolate faults in the machine.

Lifter Control
Paper inside a cassette is lifted up by the Lifting Plate.
The Lifting Plate is lifted up by rotating the Cassette 3,4 Lifter Motor (M101).
When paper surface reaches the position of the Pickup Roller, the Cassette 3/4 Paper Surface Sensor is turned ON (PS107/
PS108) to detect that the paper has reached the pickup position.
Lifter Error Detection
When the Cassette Paper Surface Sensor is not turned ON although the Cassette Lifter Motor is driven, an alarm is issued due
to error in pickup assembly.
However, at first and second failure of paper surface detection, Trailing Edge Guide Plate error is displayed on the Control Panel
to prompt the user to open and then close the cassette.
If paper surface detection fails for 3 consecutive times, no paper is displayed for the cassette and an alarm is issued.
While an alarm has occurred, the corresponding cassette cannot be used.
<Related alarm codes>
• 04-0003: Cassette 3 Lifter error
• 04-0004: Cassette 4 Lifter error

Cassette Pickup Control
Rotation of the Cassette Pickup Motor feeds paper to the Cassette Pullout Roller.
The Cassette 3/4 Pickup Roller and the Cassette 3/4 Feed Roller are driven by the Cassette 3,4 Pickup Motor (M102) while the
Cassette 3,4 Pullout Roller is operated by the rotation of the Cassette 3,4 Pullout Motor (M103/M104).
Pickup Retry Error
Pickup retry is executed when a delay jam is detected by the Pullout Sensor of each cassette.
An alarm code is notified when pickup fails the predetermined number of times.
<Related alarm codes>
• 04-0013: Cassette 3 Pickup Retry Error
• 04-0014: Cassette 4 Pickup Retry Error

Cassette Paper Size Detection
Size detection is performed to paper set in the cassette, and paper size is determined according to the setting of Paper Size
Group for Auto Recognition in Drawer (A/B size, Inch size, A/K size).
