Question about Epson AcuLaser C900 Printer

Epson Aculaser C900 photoconductor inserted incorrectly message after changing

Replaced the photoconductor unit as per the instructions from manufacturer. Despite having attempted to "refit" several times - still gives error that photoconducter fitted incorrectly. Are there sensors that could be damaged? I have tried everything - maybe I should throw the damn thing out the window! Help.

    Inky - You da best.
    Unfortunately I took the printer to the Epsom Dealer Repair Shop and they have now quoted me on needing a replacement engine board and two hours labour. I'm no techno expert so dont know - could this be the problem or am I being ripped off. Will get it back and try your advice. The cost quoted is more than half the price we originally paid for the printer. I'm in South Africa by the way. Thanks Inky.

    Dear Labatt.



    I also out of the blue recieved the message to replace my photoconductor unit



    I see that you've mentioned that the same trick will work on the Epson C1100. I've nearly completely dismanteled my PCU. I just can't seem to find anything that even remotely resembles a fuse. I've tried short circuiting the contacts with foil and then wire. Hell, I've cleaned out the waste toner compartment. No success.



    I also see someone else posting about a "kill chip". Checked out that thingy too. Tho one in my PCU is green. I Googled the number on it and it turns out to be a varistor of some sort. Is this the "kill chip"?



    Please help. I've done about 2500 prints with my PCU and really don't want to replace now

Hey Marts Try this: Remove the PCU and the Transfer belt assy's Look inside the machine to the back, top left where you will see the cam as detailed in the picture below Open the right door and you will see a Green Wheel about half way down on the back side. Turn this wheel so the cam inside turns untill it is about 100 - 110 degrees further round (anti clockwise) than it is in the picture - basically make it go as far round anti clockwise as it will go Now try reinserting the TFB and PCU assy's in turn. You do not need to insert the 2 big silver screws that hold these units in place Close her up and see how you get on. If this has no effect, let me know and I will see what else you can do.

    In my opinion it is unlikely to be the main board. Are you being ripped off - I couldn't say honestly. It is possible the main board is faulty but this is a rare occurance.

    If you have a friend or someone with a similar machine (c1900/c900) borrow their TFB abd PCU to see if the error remains.

    Try the first lot of info and see how you go. I have found on accoasion with the C900 persistance pays off. Also check all the contacts (power off first though!!) where the TFB and PCU go. make sure they are staright and protrude far enough to make contact.

I have successfully cleaned an Epson Acculaser C1900 colour laser printer.

Is anyone interested in a totorial (with photos) on doing the job. Before I had white stipes going down the pages. With a screwdriver and vacuum cleaner, it's as good as new.

THIS IS A QUICK AND VERY EFFECTIVE TRICK FOR PHOTOCONDUCTER REPLACEMENT. IT HAS WORKED FOR ME NOW IT IS ABOUT 4 YEARS DOWN, THEIR IS A HIDDEN FUSE WITHIN THE PHOTOCONDUCTOR ASSEMBLY; SILVER IN COLOUR HIDDEN BETWEEN METALIC PART /CONTACTS I WILL SEND PICS SOON. THIS IS A VERY LOW AMPERE FUSE 8ma. WHENEVER YOUR PRINTER PHOTOCONDUCTER REACHES END OF SERVICE LIFE AND REQUIRE REPLACEMENT :::THIS FUSE WILL RAPTURE::::. REPLACE THIS FUSE AND YOUR PRINTER WILL BE GOOD AS NEW. U CAN REPLACE IT WITH ANY LOW VALUED FUSE 1AMP AND BELOW WILL DO. I HAVE DONE THIS TRICK 4 TIMES ON MY PRINTER THAT HAS SINCE THEN PRINTED 102,045 PAGES. [email protected]

    Big thanks to all of you who have emailed me personally regarding the photoconductor end of life bypass procedure, Kindly note that these solution is not limited to epson c900, it works in all the entire acculaser family of printer,eg c900,1100,1000 etc.

    i will put all correspondence and solutions from people who communicated to me directly onlie.

    Hi Klabatt,

    thank you very much for your information , how to bypass photoconductor
    stop. ( Indeed my copies were absolute perfect when the machine
    stopped)

    My problem is that, with moving away the 2 metal parts, i broke the 2
    retaining pieces of plastic so cannot fix the metal pieces any more (
    may be
    glue).

    May be it is a better advise to short cicuit the 2 metal pieces
    together by
    sticking a small piece of metal ( piece of paperclip or piece of
    household
    aluminum ) over 2 metal pieces two by tape or such.

    Now i want to short circuit this fuse, but do not see any metal parts
    that
    are connected to this fuse.

    Is it conductive plastic or equivalent?

    Do you know the solution for this.

    Regards

    hi
    It is with much pleasure to hear from you. I hope that the quick fix will continue to help more and more others.
    I
    am sorry that you broke it, in a nutshell the two metal holders on both
    ends hides a fuse well fitted in some cavity within. and YES it is also
    true that by connecting the two metal pieces together will do the trick
    (that was what the fuse was doing anyway).
    For
    your case carefully glue the metal part to where they belonged and
    improvise a way of connecting both of them either by a thin wire and
    soldering or pasting some copper/alluminium foil. Make sure the
    connecting wire doesn't fall inside the printer.
    once you've done that test ur printer - working means success.
    Not
    working means the wire fell, not connecting the two plates,wire has
    some varnish coat,the two plates are not in their original points.

    try these and let me know.

    hi klabatt

    Looking close i now understand it better.

    The 2 metal contacts are going in the machine, so the tape isolated
    the
    contact.

    I solved the problem.

    thanks

    Hi there,

    We have got an Epson Aculaser c900 unit which we use in our photography
    business. It has just said that the photoconductor unit needs replacing
    and
    has come to the end of its life.

    We have just seen your article on the internet regarding replacing the
    fuse
    and thus giving it a new lease of life.

    We have done this with our other aculaser; namely a c1000 unit
    successfully.
    However, we cannot locate it on the c900. Could you please describe
    exactly
    how to get to it.

    You original thread link is shown below:
    http://www.fixya.com/support/t146110-eps...

    Many thanks for your article, we look forward to receiving your reply
    with
    some pictures showing the location if possible.

    hi there

    Re: Epson Aculaser c900 photoconductor hidden fuse location.


    thanks for your querry.
    1. remove the fuser unit
    2. the fuse is completely hidden (clear type fuse)
    3. the fuse is located between two silver metal parts against the black plastic background.
    4.
    slide one part of the metal part to see the fuse well hidden - note
    that i have received various comments from readers that they have
    broken the the metal parts conductors, the quick fix was to use some
    glue to patch brocken links.

    5. i have realised that if you dont
    want to be botherd forever about the photoconductor end of life simply
    use and aluminium/copper foil or thick wire gauge 26 to replace the
    fuse or better still use the normal 13Amps fuse wire.

    6. i will do my best to paste picture (thanks alot i had forgoten the site i pasted the end of life issue

    Hi There,



    You are amazing!



    Much appreciated. We now have a working C900 again. I am surprised there are not more posting on the web on this subject.



    We have managed to replace various fuses on our other machine in the
    past to prolong its life (and our bank balance!) ; namely Espon
    Aculaser C1000 but not on the C900.



    Thanks again, and thanks to the internet.



    Kindest regards,

    Hi could you explain further re C900 reset.





    I have a problem with PCU – one unit ran out, had a partly used
    unit, but it won’t recognise that it’s OK?






    Any help?

    hi rob

    nice to hear from you.

    1. basically the pcu will never expire, run out or decay --- only a marketing gimmick
    2. pcu can be damaged nevertheless, this can occur due to 1. exposure to light 2. bruises on the greenish part.

    3.remove the pcu,cover it with a black paper
    4. look for two metal parts along its length, slightly spaced about 2 centimeters
    5. connect the two part together with a wire or dismantle inside to find some hidden fuse.
    6. i will have some pictures online tommorow

    Rob
    avoid light exposure to the pcu totally, don't work on it in broad
    daylight, the darker ther better, scratches on pcu are permanet dents
    that will deface you printouts.

    If you followed the bypass and somehow it didn't work, check this

    - fuse (two metal parts not connected) not working thus pcu not recognised
    -check for any jam along the pcu inserting paths
    -wipe all metallic contacts on the pcu including the 2 metal parts.d

    Hi Labatt,

    You may have posted this tip 4 years ago, but I'm very grateful to you that you did. I have just replaced the fuse on my ageing C900 and it is now showing as new. You have saved me about £70. If I knew where you were, I would by you a drink. Many thanks.

Hi
I did as advised when my C1900 displayed "replace photoconductr" (Their spelling, not mine!).
I removed the unit and soldered a small piece of wire across the 2 metal strips (they're at the far end of the unit as you remove it).
Its back to perfect now!!
I'd post a couple of pictures, but I don't know how. If anyone wants to send me their email address, I'll be happy to email the pictures.

Hi guys!

Re: Epson Aculaser c900 photoconductor hidden fuse location.

Thanks for fuser info, helps great here in Rijeka, Croatia.

I do some look around this whole 'drum cartrdige' and found out some good solution for exchanging The great fuse.

On the same fuser side is possible to easily remove white plastic gear. Underneath is small hole throught which is possible with some thin stick (metal will be the best) to push out the fuse to other side and remove.

So braeking plastic or removing metal contacts is not needed.

Zlatko.

I found that the proper fuse rating is 3.15A - about £2 for 10 from Maplin. Gently gently makes replacement easy.

After changing the black cartridge of epson aculaser c1100, a message flashed: Service Req E511

The magenta & blue rollers on our Epson Aculaser C900 are printing in stripes.

quick check

1. are you running out of toner magenta and blue??

2. remove magenta and blue, shake them gently HORIZONTALY to evenly distribute the toner inside (the toner container internally has a spade that feeds the toner dust to a spongy roller then to the roller u see on the outside :) )). DON'T HANDLE THE TONER CARTRIDGE VERTICALLY ---ESPECIALLY WHEN U ARE LOW ON INK---
