    I'm getting random black splotches on b& W prints and copies. See photo. Colors don't seem to be affected. What could be causing this? Contaminated 1st BTR? Replacing the drum had no effect.

    [CQ] Re: intermittent color mis-registration

    The ITU has never been replaced. The page count on it is 109,000. Also, user says the problem has gradually become worse so it looks like the ITU is the problem.

    Thanks,

    I have a SP 5210 that needs a hard drive replaced. I haven't been able to find the key sequence to get into SP mode. Reset>806182>C doesn't work nor does the old "107" code.
    Any ideas?

    The 4525 formatters I've seen all have the battery connectors spot welded to the battery. Suggest you pull the cmos battery holder off an old PC motherboard.

    I had a HP CP4525 printer that was giving a 59.F0 error at every boot up, making the printer unusable. The cause turned out to be a failed DC Controller.

    I figured it out. It's a single unit that handles all 4 colors rather than one unit for black and a second one for CMY.

    So, am I correct: the toner pipe is held in by two screws at the front and mounted on two alignment pins at the rear?

    I think I just found it. It's in Utilities > Display Contrast. I was looking for brightness instead of contrast.

    I'm the adventurous type so I'd like to take a shot at the flex cables. It's unclear to me how to pop the top off of the carriage to get to flex cable connections. Any advice?
