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.

Turn off the power.
Loosen the screw.
Tighten the screw.

Safety Precautions
Laser Safety
Since radiation emitted inside the machine is completely confined within protective housings and external covers, the laser beam
cannot escape from the machine during any phase of user operation.
Therefore this machine is classified in Class 1 laser products that are regarded as safe during normal use according to
International Standard IEC60825-1.
How to Handle the Laser Scanner Unit
This machine is classified in Class 1 laser products.
However, inside the scanner unit, there is source of Class 3B laser beam and the laser beam is hazardous when entered into an
eye. So, be sure not to disassemble the laser scanner unit. No adjustment can be made to the laser scanner unit in this machine
in the field.
The label show in the following figure is attached on the laser scanner unit.
The following warnings are given to comply with Safety Principles (EN60950-1).
Diese Maschine ist der Klasse 1 der Laserprodukte zugeordnet.
Innerhalb der Scannereinheit befindet sich jedoch die Laserstrahlquelle der Klasse 3B und es ist gefährlich, wenn dieser Strahl
in die Augen gerät. Die Laserscannereinheit darf unter keinen Umständen entfernt werden. Es dürfen in diesem Umfeld der
Maschine keine Justagen an der Laserscannereinheit vorgenommen werden.
Das Etikett in folgendem Bild ist auf der Laserscannereinheit angebrachtt.
Toner Safety
About Toner
Toner is a nontoxic matter composed of plastic, iron and a trace of pigments.
CAUTION:
Never throw toner in flames to avoid explosion.
Handling Adhered Toner
• Use dry tissue paper to wipe off toner adhered to skin or clothes and wash in water.
2
ACHTUNG
Zweipolige bzw. Neutralleiter-Sicherung
Safety Precautions
• Never use warm water for cleaning up toner to prevent toner particles from being gelated to soak into fibers permanently.
• Toner particles are reactive with vinyl polymers. Avoid contacting these materials.
Notes When Handling a Lithium Battery
CAUTION:
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
The following warnings are given to comply with Safety Principles (EN60950-1).
CAUTION:
Wenn mit dem falschen Typ ausgewechselt, besteht Explosionsgefahr.
Gebrauchte Batterien gemäß der Anleitung beseitigen.
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.
CAUTION:
Double pole/neutral fusing

2. Technical Explanation
■ Basic Operational Sequence
The CPU on the DC controller PCB controls the operational sequence. The table below shows the operation and the purposes
in each status from start-up of the device and to last rotation after print job completion.
WAIT
(Wait)
STBY
(STBY)
INTR
(IINTR)
PRINT
(Print)
Basic Sequence
Section Outline Operation
Interval from power-ON or reactivation from sleep mode upon
shutting the door(s) to entering
the print-ready status
Interval from the wait time or the
last rotation to issuance of a print
command from the main controller or power-OFF.
Interval from issuance of a print
command from the main controller during the stand-by status to
warming up the fixing assembly
to the target temperature.
Interval from the initial rotation to
completion of last page fixation.
Activate the printer to be ready for printing. During WAIT time, the following operations are done: pressure is applied to the pressure roller of the fixing assembly;
check cartridges and units being in place; move the developing unit to the home
position; and, clean the ITB. When needed, color displacement is corrected and the
image is stabilized.
Maintain the print-ready status. The printer enters the sleep mode upon receiving
a “sleep” command from the main controller during the stand-by status. The printer
executes color displacement correction or image stabilization upon receiving corresponding commands from the main controller.
To make the printer ready for print jobs, activate high-voltage bias PCBs, the laser
scanner unit and the fixing assembly.
Based on the video signals input from the main controller, form the static latent
image on the photosensitive drum to transfer and fix the toner image on paper.
When a certain pages are printed after power-ON, the device undergoes color displacement correction and/or image stabilization.
20
Section Outline Operation
LSTR
(Last rotation)
Interval from print job completion
to motor deactivation.
The last page of the print job is completely delivered. In this status, the laser scanner
unit and high-voltage bias PCBs are inactive. The printer starts the initial rotation
upon receiving a print command from the main controller during this status.
■ Print Sequence
See "Appendix" > "Print Sequence" in this manual.
■ Print Mode
The models of this series switch among 3 print modes to optimize the paper feed speed for printing.

2. Technical Explanation
■ Major Components
Followings are the major components for Document Exposure System.
• The contact sensor to scan document.
• The Reader motor (M720), The drive pulley, The drive belt, to shift The contact sensor
In image scanning control, the contact sensor is shifted by rotating the Reader motor based on the drive signal from the Main
Controller PCB and scan the original on the copyboard glass. When ADF is in use, image is scanned by feeding the originals by
ADF instead of shifting the contact sensor.
