Symbols Explanation Symbols Explanation
Cleaning is needed. Measurement is needed.
The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specic 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
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 certied their compliance with the provisions
to market in the US. Each product shall have afxed 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
classications.

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.
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 reection has afxed the caution label at the
position shown in the gure below.

F-0-2
This product is certicated as a Class 1 laser product under IEC60825-1:2007.
But this product is equipped with a class 3B laser.
When you remove interlock and work, you must warn the safety.

Toner Safety
About Toner
Toner is a nontoxic matter composed of plastic, iron and a trace of pigments.
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.
Notes on Handling Lithium Battery
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.
Replacing with wrong battery types may cause explosion.
Follow instructions to dispose used batteries properly.

Features
Features
1. Small-size, high-speed monochrome printer
This equipment has a compact body that realizes high-speed print of 27 ppm (A4) / 26 ppm
(LTR).
2. Automatic duplex print
Automatic two-sided printing is available with standard equipped duplex unit.
3. Reduction in standby time and energy consumption
This equipment employs on-demand xing where the heater activates only during printing,
resulting in a reduction in standby time and energy consumption on this mode.
4. Realization of noise reduction and stable image quality
This equipment employs a belt drive method for transmitting the drive of the main motor.
This enables lower noise and more stable image quality compared to the conventional gear
drive method. (See NOTE)
5. Improved Usability
In this equipment maintenance (jam removal, replacing the cartridge) can be performed by
accessing one point of the delivery tray.
Note:
Changing the drive method from gear to belt reduces uneven pitch due to varied
rotation speed of the photosensitive drum, which realizes stable image quality.

ends and motors stop, indicating the purposes of intervals and engine operation. For details
of various loads, see the timing chart.

General description
■
Engine controller is the circuit to control the operation sequence of the host machine and it is
controlled by the CPU inside the engine controller.
When the power is turned ON and DC power is supplied through the low voltage power inside
engine controller, CPU starts the printer operation control.
Then, CPU drives the loads such as laser diode, motors and solenoids etc. according to the
image data that is input by the main controller when status becomes stand-by mode.
The following is the block diagram of this circuit.

Major Components
■
Followings are the major components for Document Exposure System.
• The contact sensor to scan document
• The Reader motor, 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 SCNT 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.
