This Service Manual contains basic data and figures on the GP-605/GP 605V needed to
service the machine in the field. The copier is a multifunction machine designed to provide
printer functions as an option.
This Service Manual consists of the following chapters; refer to the Copier Basic
Series as necessary for common technologies:
CHAPTER 1 General Description introduces the copier?s features and specifications, shows how to operate the printer unit, and explains how copies are made.
CHAPTER 2 Basic Operation provides outlines of the steps used to generate copies.
CHAPTER 3 Exposure System discusses the principles of operation used for the mechanical/electrical operations of the copier?s exposure system. It also explains the timing at which the various units involved are operated, and shows how they may be disassembled/assembled and adjusted.
CHAPTER 4 Image Processing System discusses the principles of operation used for the mechanical/electrical operations of the copier?s image processing system. It also explains the timing at which the various units involved 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 mechanical/electrical operations of the copier?s laser exposure system. It also explains the timing at which the various units involved are 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 shows how they may be disassembled/assembled and adjusted.
CHAPTER 7 Pick-Up/Feeding System discusses the principles of how the printer unit picks up and moves paper inside it. It also explains the timing at which the various units involved are operated, and shows how they may be disassembled/assembled and adjusted.
CHAPTER 8 Fixing System discusses the principles of how the printer unit fuses toner images to paper. It also explains the timing at which the various units involved are operated, and shows how they may be disassembled/assembled and adjusted.
CHAPTER 9 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 10 Side Paper Deck discusses the principles of operation used for the series of operations between pickup and delivery performed by the paper deck. It also explains the timing at which the various units involved are operated, and shows how they may be disassembled/assembled and adjusted.
CHAPTER 11 Installation introduces requirements for the site of installation, and shows how the printer unit may be installed using step-by-step instructions.
CHAPTER 12 Maintenance and Servicing provides tables of periodically replaced parts and consumables/durables and scheduled servicing charts.
CHAPTER 13 Troubleshooting provides tables of maintenance/inspection, standards/
adjustments, and problem identification (image fault/malfunction).
APPENDIX contains a general timing chart and general circuit diagrams.
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. |
