    eS2505AC - eS5005AC Noisy Fans

    This particular machine was starting to irritate me.

    The worst part is that the eS2505AC is located 6' from a much noisier Lexmark printer that ran continuously through the first few visits ... in which all I heard was the Lexmark. At one point I offered to come back at a time when the Lexmark would not be running, and the overhead radio maybe not quite so loud (if there might ever be a time like that).

    When I finally did get this opportunity the obstinate machine would STILL NOT MAKE NOISE. Then I got the idea that I would clean the fan blades and squirrel cages, and maybe tiewrap down any loose fan mountings. In my experience once you clean a fan that was intermittently making noise, then it buzzes relentlessly.

    There are 10 fans in the 2505AC. The IH board fan is the absolutely worst to get to, behind the system and logic boards. My noise maker turned out to be the Exit Fan F7, but I've had F2 and F4 buzz on other machines of this series. As anticipated, once it was cleaned F7 sounded like an angry nest of bees.

    All that ... just so that I could share the information I put together to individually run each fan. It didn't help me much, but you may get luckier than me: =^..^=

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    Yeah we keep several different fans in stock for these machines - they cheaped out on the fans

    Another consideration is TSB-1815 rev-02. This refers to a different harness being needed if a new fan is installed when the serial number of the copier is below a certain cutoff.

    The main culprit is usually the ozone fan at the bottom right of the rear of the machine.

    Although there's a modified one, I don't replace the fans. I take out the rubber bung located under the silver sticker and spray a bit of PTFE lubricant in there, then put the rubber bung back in and the sticker back in place.

    So far (touch wood) none have come back to bite me.

    The Dev Suction fan may be noisy especially if toner/dev is sucked in them. I had Ozone Fan noisy more often in 2500AC series. On 5005 I had F7 fan as mentioned, Fuser cooling Fan and in one occasion the LSU Fan.
