    Solution
    CAUSE: Failed Hard Disk Drive (HDD).
    SOLUTION: Remove the hard drive as a test to see if the MFP boots. If so, replace the hard drive (p/n
    A2X0 M72C 00).
    I tried to remove HDD and turned on, cannot fix.
    Removed RAM and did once more, same result.

    Are you getting clear AC from the wall? The all solutions PDF could help.

    Could be the MFPB... But give it a firmware flash for good measure.
    As far as i looked through it, there is nothing in it

    im pretty sure a C35 requires the RAM (not optional) so removing it if anything would make the problem worse. It would need swapping with known working DIMM to be of any troubleshooting use

    I'd replace the ram chip first.

    We had many of these machines with this problem. Ultimately ended up having to replace the MFPB, which comes with the SSD. Printer_Error_Locking Up at Startup _ Stuck on hourglass (Technician).pdf7829.pdf

    See the attached PDF's.

    if your about to spend the money on main board on such a old printer id just quote on replacing it with a C3350i

    Lets be honest C35 were bad and this is good reason to justify upgrade

    Yup, it's a nice suggestion, i will try to discuss with customer.
    On the other hand, i found one used MFPB, can I replace it with SSD that installed on defective board, no need to perform dip switch setting? ( counter data transfer )
