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,
accompanies the symbol
represents the path of mechanical drive—where a signal name
, 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 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 reasons, 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.

CHAPTER 1 GENERAL DESCRIPTION
I. FEATURES
1. Personal Copier with a Zoom Function and a Fixed Copyboard
• You can choose either a default enlargement/reduction ratio or any ratio between 70% and
141% in 1% increments.
2. Ecology-Conscious
• The use of a roller charging method has resulted in a considerable reduction of ozone: 0.01
ppm or less on the average, 0.02 ppm or less at maximum (1/100 to 1/1000 compared with
existing Canon machines).
3. SURF Fixing Assembly
• The wait time is 0 sec (at 20°C room temperature), enabling speedy copying work immediately after power-on.
4. Various Paper Sizes
• The paper may be between A4 (LGL) and A5 (STMT) (*Using the universal cassette).
• In manual feed mode, paper may be as large as A4 (LGL) or as small as a business card.
5. All-in-One Cartridge for Simple Maintenance
• The photosensitive drum, toner case, charging roller, developing assembly, and cleaning assembly are constructed as a single entity (cartridge).
The user may expect quality copy images at all times as long as he/she performs simple
replacement/cleaning work.
6. Large Paper Source
• The source of paper may contain as many as 550 sheets of paper (500-sheet cassette +
multifeeder; multifeeder type).
7. Separate top unit
• The machine’s top unit may be opened to make jam removal easy.
8. ADF Type
• Continuous copying is possible with the use of the ADF.
