This service manual provides basic information required for performing field service to maintain the product quality and functions of the this machine. The structure of the manual is as described below.
Each chapter consists of the following sections.
Chapter 1, “Introduction,” : Features, specifications, operation methods, copying process.
Chapter 2, “Basic operation,” : Explanation of the machine’s basic operations
Chapter 3, “Exposure system,” : Explanation of the exposure system’s mechanical / electrical system operating principles, timing, disassembly, assembly and adjustment methods.
Chapter 4, “Image processing system,” : Explanation of the CCD, analogue / digital image processing, disassembly, assembly and adjustment methods.
Chapter 5, “Laser exposure system,” : Explanation of the laser exposure system’s mechanical / electrical system operating principles, timing, disassembly, assembly and adjustment methods.
Chapter 6, “Image formation system,” : Explanation of the image formation system’s mechanical / electrical system operating principles, timing, disassembly, assembly and adjustment methods.
Chapter 7, “Pick-up / Feed system,” : Explanation of the pick-up / feed system’s mechanical / electrical system operating principles, timing, disassembly, assembly and adjustment methods.
Chapter 8, “Fixing system,” : Explanation of the fixing system’s mechanical / electri-cal system operating principles, timing, disassembly, assembly and adjustment meth-ods.
Chapter 9, “Outer cover / auxiliary control system,” : Explanation of the outer cover / auxiliary control system’s mechanical / electrical system operating principles, timing, disassembly, assembly and adjustment methods.
Chapter 10, “Cassette feeder,” : Explanation of the cassette feeder’s mechanical / electrical system operating principles, timing, disassembly, assembly and adjustment methods.
Chapter 11, “Installation,” : Conditions relating to the place of installation, and the installation procedures.
Chapter 12, “Maintenance and Inspection,” : Table of periodic replacement parts and consumables replacement targets, periodic service list and parts to be cleaned during a customer service call.
Chapter 13, “Troubleshooting,” : Standards / adjustments, operation failure counter-measures and delivery failure countermeasures
Appendix : General timing chart, general circuit diagram, etc..
The explanations in this manual are based on the following principles.
1. Each chapter gives an overview of each function's purpose, role and the connection between the electrical and mechanical systems as well as the operation timing of each part.
In the outline diagram, the signal shows the mechanical drive transmission.
When the signal is shown with a signal name, it indicates the electric signal flow.
In the explanation of this units digital circuit, “1” is indicated when the signal's volt-age level is high, and “0” is indicated when it is low. However, the voltage value will differ depending on the electrical circuit. Furthermore, the * in the signal value [DRMD*] shows the DRMD signal is “0” and ON.
In each chapter, [Power supply ON] indicates the power supply SW has been turned "ON", the front door, etc., has been shut, and power is being supplied to the copier.
2. This unit utilizes micro processors, however, due to the impossibility of checking the micro processor's internal operation, an explanation of the micro processor's opera-tion has been omitted. Furthermore, assuming that internal repair of the print circuit board will not take place on the customer's premises, the explanation of the circuit in
the print circuit board's circuit is limited to an outline explanation using a block dia-gram.
Consequently, the electrical circuit explanations consist of 2 types, from the sensors to the main circuit board’s input section, and from the main circuit boards' output section to the load, and block diagrams by function.

| Nary Preng | 2008-02-07 19:36:04 | | I want to know this program before i buy it. Can you explain me about your program i had many problem with my printer of Epson R270. | |  | michel jacquemin | 2022-07-12 15:53:28 | I just bought a reset key, everything works perfectly on a Epson XP 520.
Just one thing, one key for several reset will be better.
Thank you for your job. | | | Kenneth Threlfell | 2024-05-26 00:31:44 | | When my printer quit working, I ordered a new printer. Then I decided to check youtube to see if anything could be done other than taking it in. That's when I found WIC.
This process was so easy, I cancelled my order for a new printer and fixed this on in less than an hour. I ordered new pads and entered the code to reset.
Code cost me less than 10 dollars, and 2 sets of pads for 15 dollars. Better than iver 300 for a new printer. | | | KEITH RICHARD FIRME | 2021-04-10 07:08:57 | | BRILLIANT!!!!!!!
You deserve every dollar you make from your extraordinary program and service. THANK YOU SO MUCH!
In awe of you, that you could produce, make, create this reset program so that even I, 78 yrs. old, mostly blind and not much of a computer geek, could do it! I al thrilled and jumpinga round because you saved me about $300>$400 from not having to buy a new printer. | | | Morris Gven | 2015-02-27 14:36:17 | | Thanks for your advice. I had the printer Epson Pro 4900 attached to the network.
Once I used the USB connection everything worked great.
There were 2 ink channels that I could not clean.
After poking around the internet I found discussion of air in the lines.
Did an initial charge and now things are working perfectly.
Thanks for a great product and tech support.
Regards, Morris Gven | | | Brent Buttorff | 2024-03-02 20:36:42 | | I was skeptical, but I paid for a key and the WIC Reset Utility program worked PERFECTLY on my Epson ET-2400. Thank you! | | | planeta cartucho | 2009-06-20 19:32:14 | | Excellent value for money. Try It, you\'ll see! | |
