Explanation of Symbols
The following symbols are used throughout this Service Manual.
Symbols Explanation Symbols Explanation
Check. Remove the claw.
Check visually. Insert the claw.
Check the noise. Use the bundled part.
Disconnect the connector. Push the part.
Connect the connector. Plug the power cable.
Remove the cable/wire
from the cable guide or wire
saddle.
Turn on the power.
Set the cable/wire to the
cable guide or wire saddle.
Remove the screw.
Tighten the screw.
The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specic 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 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
in the eld. 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.

CDRH Provisions
Food and Drug CDRH (Center for Devices and Radiological Health) under FDA (Food and
Drug Administration) enforced provisions of the section for laser and laser products on August
2, 1976. These provisions are applicable to all laser products manufactured or assembled
after August 1, 1976 and allow only products certied their compliance with the provisions
to market in the US. Each product shall have afxed the applicable label as shown below to
follow the labeling requirements prescribed in CDRH provisions.
Note that the wording included in labels is different depending on laser product
classications.
F-0-1
Laser Safety
About Laser Beams
Laser radiation may be hazardous to human. The laser scanner unit mounted in this device is
sealed in the protective housing and the external cover to prevent laser beams from leaking
to the environment. As long as the device is operated under normal conditions, users are
safely guarded from laser leaks.
This product is certicated as a Class 1 laser product under IEC60825-1:2007.
Handling Laser Scanner Unit
Before providing service works for the laser scanner unit and its peripherals, ensure to turn
off the power of the device.
Any cover with potential dangers of laser beam reection has afxed the caution label at the
position shown in the gure below.

Toner Safety
About Toner
Toner is a non-toxic material composed of plastic, iron, small amount of pigment, etc.
Never throw toner in ames to avoid explosion.
Handling Adhered Toner
• Use dry tissue paper to wipe off toner adhered to skin or clothes and wash in water.
• Never use warm water for cleaning up toner to prevent toner particles from being able to
soak into bers permanently.
• Toner particles are reactive with vinyl polymers. Avoid contacting these materials.
F-0-3
Notes on Handling Lithium Battery
CAUTION:
The battery installed in this machine is xed and cannot be replaced.
When disposing of an old battery, remove it from the PCB and follow the
local regulation.
The following warnings are given to comply with Safety Principles (EN60950).
Achtung:
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.

Product Features
1. Compact/high-speed printer
This machine is a high-speed B&W printer with a compact body design and the print speed
of 19 ppm (LTR).
2. Reduced standby time and low energy consumption
This machine uses the on-demand xing method in which power is supplied to the heater
only at printing.
This realized the reduction of standby time and low energy consumption during standby.
3. Reduced operation noise and stabilized image quality
This machine uses the belt drive method for the Main Motor's drive transmission.
The operation noise is reduced and image quality is stabilized compared to the
conventional gear drive method (see NOTE).
4. Improved user operability
User operability is improved by concentrating the maintenance processes (jam removal
and cartridge replacement) in a single location at the Upper Cover.
Note:
By changing the drive method from gear to belt, uneven cycle of the Photosensitive
Drum is reduced. This makes it possible to realize stabilized image quality.
