The copier is a multi-function copier capable of serving as a copier, fax, and printer.
This Service Manual provides information needed to service Canon GP-405/GP-335 (GP 405/GP 335) in the field. For information on technologies used in common with the existing copiers, refer to the "Copier Basic Series" as necessary.
This Service Manual consists of the following chapters:
Chapter 1 General Description introduces the copier's features and specifications, shows how to operate the copier, and explains how copies are made.
Chapter 2 Basic Operation provides outlines of the copier's various mechanical workings.
Chapter 3 Exposure System discusses the principles of operation used for the copier's lens drive unit and scanner drive unit. It also explains the timing at which these drive units are operated, and shows how they may be disassembled/assembled and adjusted.
Chapter 4 Image Formation System discusses the principles of operation used for the copier's image processing units. It also explains the timing at which the various units involved in image processing are operated, and shows how they may be disassembled/assembled and adjusted.
Chapter 5 Laser Exposure System discusses the principles of operation used for the copier's laser unit. It also explains the timing at which the unit is operated, and shows how they may be disassembled/assembled and adjusted.
Chapter 6 Image Formation System discusses the principles of how images are formed. It also explains the timing at which the various units involved in image formation are operated, and show how they may be disassembled/assembled and adjusted.
Chapter 7 Pick-Up/Feeding System explains the principles of picking up and feeding copy paper in view of the functions of electrical and mechanical units used to move copy paper and in relation to their timing of operation. It also shows how these units may be
disassembled/assembled and adjusted.
Chapter 8 Side Paper Deck explains the principles of operation used from when paper is picked up to when copies are delivered. It also explains the timing at which various drive units are operated, and shows how they may be disassembled/assembled and adjusted.
Chapter 9 Fixing System explains the principles used to fuse toner images to transfer media in view of the functions of electrical and mechanical units and in relation to their timing of operation. It also shows how these units may be disassembled/assembled and adjusted.
Chapter 10 Externals/Auxiliary Mechanisms shows the copier's external parts, and explains the principles used for the copier's various control mechanisms in view of the functions of electrical and mechanical units and in relation to their timing of operation. It also shows how these
units may be disassembled/assembled and adjusted.
Chapter 11 Systems explains connections and specifications related to systems
and shows how to disassemble and assemble them.
Chapter 12 Installation introduces requirements for the site of installation, and shows how the copier may be installed using step-by-step instructions.
Chapter 13 Maintenance and Servicing provides tables of periodically replaced parts and consumables/durables and scheduled servicing charts.
Chapter 14 Troubleshooting provides tables of maintenance/inspection,
standards/adjustments, and problem identification (image fault/malfunction).
Appendix contains a general timing chart and general circuit diagrams. |
