FC 200, 220, PC 400, 420, 430 Copiers SERVICE MANUAL

This Service Manual provides information needed to service the plain paper copiers FC200/PC400(120V model), FC220/PC420(120V model), and PC430(LGL model) in the field.

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 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 5
“Pick-Up/Feeding System,” explains the principles used from when copy paper is picked up to when a copy is delivered 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 6
“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 7
“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 8
“Installation,” introduces requirements for the site of installation, and shows how the copier may be installed using step-by-step instructions.
CHAPTER 9
“Maintenance and Servicing,” provides tables of periodically replaced parts and consumables/durables and scheduled servicing charts.
CHAPTER 10
“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 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, represents the path of mechanical drive where a signal name accompanies the symbol , 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.
Note:
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.

  Fantastic. Does exactly what it says. Easy to use and saved many a printer from the waste tip.

  I just used this utility on an Epson XP 810. Worked like magic. First the trial version,this brought my printer back to life immediately. Then i bought the reset key, and according to the program, the waste counter is now set to zero. I replaced the inkpads with thightly packed adsorbent paper, so for less than ten dollars I have a fully working printer /scanner/copier again. Thanks! Chris

  I have modified the firmware of an Epson wf3620 with the firmware key to make the printer run with chipless ink cartridges. The instructions were clear but must be followed exactly in order for the process to be successful. I am very happy with the result as I have the freedom to use oem ink or not depending on my needs. No oem cartridges now work perfectly well. Well done wic utility people. regds, Peter.

  Dear John Re: 20748 / 20995 I would like to take this occassion to to say "Thank Very Much" for your reset product (WIC) on my epson sx115's. They worked perfectly and certainly did the job! I will buy from you again in the near future and would like to confirm that i would have no hesitation to recomend you to anybody. Keep up the good service. kindest regards Dave Burrow photographixdesign

  Very impressed! After a fruitless search for official Epson support for the Waste Ink error I found a YouTube video showing how to remove and clean the ink pads but still needed to reset the counter. After some initial "Is this unofficial 3rd Party Solution a scam?" trepidation I took a chance on the WIC reset tool and now, about half an hour (mainly spent drinking tea and waiting for the key to be emailed) and 6 quid later I have a fully functioning XP-342. In the meantime, Epson UK responded to a message I sent them on Twitter, telling me that I could send the printer away to their service centre for an unspecified period of time and pay them £48 to have the ink pads changed and the counter reset. All with a caveat that having "tampered" with the ink pads myself, the service centre might refuse to fix the printer. Thanks for a great piece of kit which has saved me a lot of time, effort and money.
