Re: Sharp mx-2300n Colored Lines On Paper

Was the machine plugged in when you pulled the memory? =^..^=

I believe it may well have been yes. Oops?

Uh oh!

what next? Anything that I can do? Can be done? :-(

if the memory is removed with the machine off is that okay?
also what about the removal of the EPROM : is that also okay to remove so long as the machine was switched off?

Has the board lost it's memory?

thanks on advance

If you are very lucky, only the memory is dead. I can't say I've ever made this particular mistake before, but who knows? I may yet.
So I have no experience with this situation. =^..^=

Zootech, Akitu

thanks both for the replies. I had been re-seating the memory as per one of the earlier posts and swapped out one dimm from a different machine (also faulty), I have now since doing so, got the error:

Call for service. Code U2-30.

I've downloaded the service manual, and it says:

"Cause:
EEPROM is not changed when the PCU/MFPcnt
PWB is replaced.

Check and remedy:
1) Check that EEPROM is properly set.
2) Check that EEPROM on the previous PWB is
inserted to the newly installed PWB.

I have tried re-seating the EEPROM, but it has made no difference?

I hope I haven't caused any further damage!

please help.

So... You're not a tech or you just didn't have the manual? The whole "I downloaded the manual" thing is very unnerving. Do you know what the EEPROM is? I would recommend contacting your local Sharp representative. You've done enough damage as is.

I believe that error code will require new eeproms from Sharp.
Big oops indeed!!!!!
My former boss thought it would be wise to change a light fixture with the power on a few years back. Fell of a ten foot ladder, and landed on his head.
He can no longer remember what he had for breakfast and frequently wets himself.
Step #1 : pull the plug!!!

Well, anyone who has access to elevated sims can reprogram the EEPROM data themselves, but I wouldn't trust it to an end user who wants to play technician by downloading the service manual online.

Re: Sharp mx-2300n Colored Lines On Paper

Hello,
I am having the same problems with magenta streaks coming out when I print things. If I copy things the streaks do not appear only when I print. I have opened the side and cleaned the secondary transfer belt and the drum unit which both had magenta toner on them. When I closed it back up and printed again the magenta toner came back in the same places. I want to open the unit up to get a look at the primary transfer belt but am unsure of the best way to do that. Images attached.

Hi I have quite similar problem. Yours above 2 pictures are like mine. I tried copy and I have problem with Magenta too. My copies look like:

Red lines on the top.
I put developing unit + drum unit (magenta) into other machine and there were no problem. I put deve + drum unit back and I insert another Magenta toner cartridge but my copies are still with this red line. My secondary transfer belt looks like yours.
Can anybody advise what else should I check.

Regards

Why did you try changing the toner cartridge? These aren't inkjet machines.

It seems to me that I had a similar problem and it turned out to be the secondary transfer board. Back of copier top left.

I changed this board but it did not solve the problem. Red belt is still printed.
Does anybody has another idea please?

Re: Sharp mx-2300n Colored Lines On Paper

hello all I had this problem before.long time ago
the solution=
where you drum slides to the guides on the rear frame there is 2-red screws.
adjust them little by little until no more magenta banding

or was it for the developer unit try one at a time
