NP 6330 Copier SERVICE MANUAL

This Service Manual provides the basic facts and figures about the plain paper copier NP6330 needed for servicing it in the field.
The NP6330 is designed to enable full automation of copying work, and may be configured with various accessories.
(For detailed descriptions of sorters, ADFs, RDFs, and controllers, see their respective Service Manuals.)

This Service Manual covers the NP6330 and the pedestal, and is organized as follows:

Chapter 1
General Descriptionintroduces the copier’s features and specifications, shows how to operate the copier, and explains how copies are made.

Chapter 2
Operations And Timing discusses how the functions of the mahine work and provides outlines of electric circuitry and sequence of operations.

Chapter 3
Exposure Systemdiscusses 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 Systemdiscusses 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 Systemexplains 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 Systemexplains 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
Controls And Externalsshows 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
Paper Deck Pedestal explains the principles of operation of the paper deck pedestal in view of electrical and mechanical units and in relation to their timing of operation. It also shows how the unit may be disassembled/assembled and adjusted.

Chapter 9
Installation introduces requirements for the site of installation, and shows how the copier may be installed using step-by-step instructions.

Chapter 10
Maintenance and Inspection provides tables of periodically replaced parts and consumables/durables and scheduled servicing charts.

Chapter 11
Troubleshootingprovides 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.
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 copiers 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.
All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Informationbulletins and be able to identify and isolate faults in the copier.

  I purchased the epson adjustment program last night and got to work on it today.
I had a clog in C and it would not clear. I ve had my 4900 for over 2 years and have been able to handle them until now.
I learned about this site from another site that has cleaner for the 4900 and said I need to buy this software first. I bought it and tried it with the epson ink that was in my printer. I ran the adjustment and it cleared C but then there were other clogs. Because they werent clogged before I started, I cleared them the normal way through the printers options. Had they not cleared, I would have ran the adjustment again.
I had tried everything to get C to clear for a week and this program did it in one try!

I would highly recommend this for clearing a stubborn clog. And now it is in my arsenal if I get another one that I cant clear down the road. By the way, it does not work if your printer is networked. Mine was so I had to move a computer into the room with my printer, directly connect to it and install the drivers. Then it work fine.
If you got a clog that you cant fix, just buy it.

  Hi, I'm particularly satisfied of the Wic Reset Utility I just used for the 3rd time (2020, 2022 and now) for my Epson WP635 Printer. I had felt pads left from the last time, easily replaced them thanks to the excellent instructions found on octoink's site, then bought a new key and re-intitialized my printer in minutes. My printer is now renewed for 2 years! Very very satisfied. Many thanks. MF, France

  Thank you, got it on-line!

  Works slick...and why shouldn't they make some $$ for their key and Utility? I appreciate not having to send the printer to Tech support or buy a new one like Epson suggests- when it was a piece of cake to do myself.

  Usual 'Service parts inside printer' etc. message on my Epson RX640. None of the freeware solutions worked, so I was a bit dubious about this. I have to say it worked a treat!! No problems at all. It reset the waste ink counter, I cleaned the waste ink pads and so for £6.32 I've got a new printer. :-) Recommended.
