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.

Notes on Assembly/Disassembly..........2

Notes Before it Works Serving
• At servicing, be sure to turn OFF the power source according to the specified steps and disconnect the power plug.
• Be sure to disconnect the power plug on a regular basis and remove dust and dirt accumulated around the outlet with dry
cloth.
CAUTION:
Leaving the power plug connected for a long time in an environment having a lot of dust, moisture, or oily smoke will
cause a fire. (Because dust accumulated in the surrounding area will absorb moisture and cause an insulation failure)
Points to Note at Cleaning
When performing cleaning using organic solvent such as alcohol, be sure to check that the component of solvent is vaporized
completely before assembling.
Notes on Assembly/Disassembly
Follow the items below to assemble/disassemble the device.
1. Disconnect the power plug to avoid any potential dangers during assembling/disassembling works.
2. If not specially instructed, reverse the order of disassembly to reinstall.
3. Ensure to use the right screw type (length, diameter, etc.) at the right position when assembling.
4. To keep electric conduction, binding screws with washers are used to attach the grounding wire and the varistor. Ensure to
use the right screw type when assembling.
5. Unless it is specially needed, do not operate the device with some parts removed.
6. Never remove the paint-locked screws when disassembling.

Controls
Lifter control
Paper inside a cassette is lifted up by the Lifting Plate.
The Middle Plate is lifted by the rotation of the Cassette 3,4 Lifter Motor (M102).
When the paper surface reaches the position of the Pickup Roller, the Cassette Lifter Sensors(PS104/PS105) are turned ON to
detect that the paper has reached the pickup position.
Lifter Error Detection
If the Cassette Lifter Sensors are not turned ON for 5 seconds or more, no paper is displayed for the corresponding paper source
and an alarm code is issued.
NOTE:
Related Alarm Code:
04-0001: Cassette 1 Lifter Error
04-0002: Cassette 2 Lifter Error
04-0003: Cassette 3 Lifter Error
04-0004: Cassette 4 Lifter Error
Cassette Pickup Control
Rotation of the Cassette 3,4 Pickup Motor (M101) feeds paper to the Vertical Path Roller.
The Cassette 3/4 Pickup Roller and the Cassette 3/4 Feed Roller are driven by the Cassette 3,4 Pickup Motor (M101) while the
Vertical Path Roller is operated by the rotation of the Cassette 3,4 Feed Motor (M103).
Pickup Retry Error
Pickup retry is executed when a delay jam is detected by the Vertical Path Sensor of the respective paper source.
An alarm code is notified when pickup retry fails the predetermined number of times.
NOTE:
Related Alarm Code:
04-0011: Cassette 1 Pickup Retry Error

The paper size in the cassette is automatically detected by the Cassette Size Switch A/ B after the position of the Guide Plate is
adjusted. The switch consists of 3 microswitches, and length and width are detected in accordance with the combination of ON/
OFF. When the cassette presence/paper size is changed, the DC Controller notifies the Main Controller of the status change.
In addition, the distinction between A5-R and STMT-R is determined by the user while that between EXEC and K16 is determined
by the service technician.
