    In fact most of the techs I know around me prefer to lay on their vast experience(20+ years) and stay in analog era. They can handle any mechanical problem, but reading a book is big no-no for them.
    That's fine but at some point they will start to fail against new technologies.
    I highly appreciate senior members here with their experience and their development sometimes from typing machines of 70-80s to the nowadays when they are leading force of this fine Forum.

    Been fixing design problems on theses machine for years these engineers are not all saints. The spring i mention does not press the roller against the drum that is 2 other springs doing that.
    The spring i refer to is for the paper guide only and the spacers for that guide press against the drum.
    Whatever

    Re: Transfer Roller damaged, damaging Drum Unit

    hey copiernerd, another idea, what if the contents of the dev unit were not circulating properly because of tank design, and over time the contents separated so that larger magnetic particles ended up at one end and smaller particles ended up at the other. I've seen dev spacers get blamed for faults when they were innocent

    61yrs is still not to late in life to learn..but I find I do have a harder problems with lazy/people with lacking common skills/knowledge.

    But the book can only lead you so far.. Iíve lost count of the times that my fellow younger engineers have fitted parts (usually expensive ones) because the manual says so, only to find itís something else not even suggested. I always say to my guys that the manual only tells you how it works, not how it goes wrong!
    Intuition and experience count for a lot in this game.
    Iím not saying you shouldnít use manuals ( you have to for codes etc) but as far as Iím concerned a manual is a tool to be used along with a good knowledge of the copy process and a well developed troubleshooting process.
    Phew I feel better now! Rant over.

    Means what you think, seniors here in CTN.
    Take care and stay here even new challenges are more thrilling

    P.S
    And yeah this young buck copier nerd is pretty cocky, but still may became valuable member here...one day.

    Re: Transfer Roller damaged, damaging Drum Unit

    Had one where the transfer roller metal guide was bent recently did exactly the same as you pictures.
    Not buying the mag brush theory on this one. look at the nature of the damaged. Mag brush will polish the surface off.
    Whatever

    Re: Transfer Roller damaged, damaging Drum Unit

    if you line up the transfer roller and the drum you will see what the wear is. remove the two screws on each end of the transfer roller and remove all but one on each side (black spacer) i have replaced new dev and still did it within 100k. its too much pressure on the drum. dev unit can and will do more damage when they get too bad on the dev unit

    What contents do you think may not circulating properly? when i rotate the gear manually, it circulates smoothly not stiff and mag brush is uniform, also circulating properly. There is no excessive developer deposited at any side.

    DV Spacers circulate with a bearing inside. If that bearing comes out due to any reason the space or gap at that particular spacers becomes narrow and surface of drum gets in contact with the magnet roller. as a result drum get damage.

    In this case there is no such signs. I have to trace the problematic part before replacement of transfer roller and drum unit.
