This Service Manual provides basic facts and figures needed to service the GP215/GP200 in the field.

The GP215/GP200 is designed to accommodate fax and printer functions in addition to copier functions,

and separate service manuals are available for each function; refer to the appropriate service manual as

necessary.

This Service Manual is organized as follows:

CHAPTER 1, “General Introduction,” shows the GP215/GP200’s features, specifications, and step-by-

step instructions on how to operate the copier.

CHAPTER 2, “Copying Processes,” shows how the GP215/GP200 generates copies while discussing

each of the steps involved.

CHAPTER 3, “Operations and Timing,” explains the GP215/GP200’s mechanical system by function

and principles behind its electrical systems in relation to timing of each operation.

CHAPTER 4, “Mechanical System,” explains how to disassemble/assemble and adjust the

GP215/GP200.

CHAPTER 5, “Installation,” provides points to note when selecting the site of installation and instruc-

tions on how to install the GP215/GP200.

CHAPTER 6, “Maintenance and Inspection,” provides tables of periodically replaced parts and con-

sumables/durables as well as a scheduled servicing chart.

APPENDIX contains a general timing chart, general circuit diagrams, and PCB diagrams.

This Service Manual is accompanied by the Service Handbook, which contains information on how to

maintain and inspect the GP215/GP200 through adjustment and troubleshooting work.

Information found in this manual may be updated from time to time for product improvement, and major

updates are communicated in the form of Service Information bulletins.

All service persons are expected to be thoroughly familiar with the contents of this Service Manual, the

I. FEATURES

1. Establishes a new set of standards for “high-quality imaging” at a resolution of 1200

××

600 dpi

(equivalent), which is the world’s first.

• In copier mode, the resolution is 600

××

600 dpi when reading and 1200

××

600 dpi when writ-

ing.

• In fax reception mode, the resolution is 600

××

600 dpi (hyper genesis smoothing).

• In printer mode, the resolution is 1200

××

600 dpi (new super smoothing technology).

2. Ease of operation and productivity from an integrated design.

• The display is a large LCD touch panel for clear viewing and simple operation. (The display

intensity may be varied.)

• The on-going fax communication status may be indicated while in copier mode.

The display indicates the status (reception/transmission) job number, fax number, party num-

ber, and number of processing pages at intervals of 1 sec.

3. Power-saving, space saving, and ozone-less considerations for the office and the environment.

• The on-demand fixing method warms up the machine quickly so that sleep mode may be

made use of without the risk of wasting time.

• The wait time is 8 sec or less. (at power-on on the control panel; 8.6 sec or less if the main

switch is used)

• The machine is appreciably quieter than the existing models for a better office environment.

• With the help of its power-saving design, the power consumption is 4 W or less* in sleep

mode (about 1/25 of existing Canon models) and 57 W or less** in standby (about 1/4 of exist-

ing Canon models).

• The roller charging method has enabled ozone-less operation.

• The width is only 58.5 cm. With the MDC function built into the machine, more space is saved.

All additional copier, fax, printer, and network functions may be built into the machine with-

out affecting the machine size.

4. GP215 Series with duplexing functions

• As many as four models are available—with combinations of copier, copier/fax, and copi-

er/printer.

• The copier/fax model comes standard with an ADF-F1 or an RDF-G1.

: Standard : Option : Either copyboard cover, ADF-F1, or RDF-G1. (as an option, PostScript Level 2).

* Sleep state is when the main power is OFF. Fax reception is possible. (Not 4 W if a fax transmission

reservation has been made or the printer function has been added.)

** Standby state is when the main power is on. In copier/fax mode, 57 W or less. In copier mode, 50 W

or less.
