C2880 wont boot up

[repeatcopiers]

I have a C2880 in the shop that was working fine and then the control panel went crazy, it was going to Send by itself and flickering then the screen went black. I turned it off and back on and now it won't boot up. The bar only barely gets started, like a 1/4 of an inch and you can hear all the start up sounds like normal then it just stays like that, never throws a code or anything. I have a parts machine and swapped out the bootrom, hard drive and memory sticks but no change....any ideas?

Re: C2880 wont boot up

First I would try reseating all the connections in the back of the machine, basically remove & refit all the boards etc, common fault on this old model now.

Re: C2880 wont boot up

I would look at the RAM and main controller first

Re: C2880 wont boot up

Ok, so I replaced the main controller now it works fine except look at the example of a color copy attached.......Could I have plugged something in wrong? The b/w is fine, just color looks like this.

Yes you probably got a connector not in all the way or wrong. Especially check the flat cables. Re seat all cables.

Ok so I have reseated everything on the Main Controller and the flat cables between the dc driver and dc controller, still same problem. I have attached a copy of my PG10, does this narrow anything down??

OK i'm assuming the quality was perfect before you stated work on the machine, yes it wasn't booting up but did the customer mention bad quality?

The main board you replaced was it new or from another machine? If it was used do you know 100% it was a good working board?

NOTE: WARNING

If you pull out the SRAM PCB from machine B and mount it to machine A,
the PCB will be initialized and be rendered useless for machine A or B.

FOR DIGITAL ISSUES/LINES = Also Check
on Main controller PCB ( the sub PDRM-EF-A Boards)====they control > image processing for printer output (color space compression, background removal, LOG conversion,
direct mapping, color balance, zoom fine adjustment, gradation conversion, screen processing,
framing, add-on)

The Upper PDRM-EF-A board controls Magenta and Cyan/ the Lower controls Black and Yellow

REMOVE and clean their contacts with alcohol, when dry > re-insert them/ ( u can swap these for testing )
Also clean contacts and re-seat that top small sub RA Board = (controls >color space conversion, rotation for electronic sorting, binary processing, resolution conversion)

Your PG10 Has Digital Lines > also missing are the CYAN and YELLOW Horizontal Blocks

Well I have reseated and then replaced the small sub RA board and both of the PDRM-EF-A boards and no change. I guess I must resign myself to the idea that this main controller might be bad, it came off a parts machine but at one time the main controller was good. Thanks for all the help and suggestions. I noticed one thing that I am wondering about, 2 of the PDRM-EF-A boards have a green led that lights up and 2 of them didn't light up, I tried both sets without a change so I'm curious are the 2 that don't light up bad?

As you have swapped over the PDRM-EF-A boards and the colours haven't changed, the connector in the main controller must be bad.

===========================

Agree on Main Pcb Issue with board or it connections


PDRM-EF-A boards usually throw an Error Code or Digital Lines (poor contacts/connection)

Re: C2880 wont boot up

We ended up putting another Main Controller in and everything is working fine. Thanks for the help everyone!
