    Then i´ve removed the entire Pickup Assembly and found out a snaped spring (piece 54 below).

    Attachment 39105

    I´ve replaced the spring but it´s not working.

    I´ve assembled the pickup assembly again, inserted trays and by hand i´ve pulled the lifter up from both trays and they worked ok.

    It seems that when the tray is inserted i hear and see the chain nr. 69 from the assembly rotating but does not operate the lifters.

    could it be the pickup PCB or coud it be a gear inside the pickup assembly that went bad? what do you think?

    regards

    ============================
    do u hear a noise if paper is loaded in trays ???

    did u check that ratchet gear for crack in posted picture ????

    Just be sure to put everything back on the gears and springs

    Do you mean the noise as if the lifter was operating? no, it makes no noise. The only noise is from the belt operating inside the pickup assembly.

    did not check the ratchet gear but if i put the lifter up by hand I feel all the tooth ok. Also the lifter stays up and do it´s thing but has soon has I remove the tray, the lifter goes down and does not come up again.

    maybe the spring that snapped caused the gears to go out off place. I´ve assembled all ok, but maybe the gears should be in a certain position to work.

    I´ll take the assembly out again for checking all the gears. Maybe by hand i can see if they are at the right position to work. Do you think it cannot be a sensor from the Pickup PCB gone wrong?

    What did u take apart ?



    Moving Up the Lifter

    When the main power is turned on with the cassette set in the machine or the cassette is slid in while the machine is in standby state, the pickup roller shaft moves down to push
    down the lifter trigger lever.
    The cam is released when the pickup roller shaft pushes one side of the lifter trigger lever, and the drive from the main motor (M1) move sup the lifter.

    When the pickup roller remaining in contact with the paper surface moves up to a specific height, the movement of the levers cause the pickup roller shaft to return to the uppermost
    position to end the upward movement of the lifter.

    Lifter.jpg
    Detecting the Level of Paper
    The level of paper inside the cassette is detected by the light-blocking plate of the lifter gear and a sensor in relation to the distance over which the lifter moves up.
    When paper starts to run out, the lifter gradually moves up; when paper fully runs out, the cassette paper sensor (Q1604 for cassette 1) identifies the condition as indicating the absence of paper.

    The parts that i removed where those in green. The spring that snapped was the one that hold the white piece and i put a new one.

    Now the red part it seems to be out of place. I think it should do some function for operating the lifter has it should connect to the white big rotating gear.

    what do you think?

    I spent many years working on this model & this fault.

    This lifting issue can have many different causes as listed in the pdf.

    However the most common reason I saw was the spring mounts would snap off, since this mount was part of the frame it cant really be repaired, however I did have some success gluing it back on.

    But most times I would simply replace the complete PF unit.

    Ok, just saw and the whole unit is super expensive. I´ll open it again and try to see what´s wrong inside it. The spring mounts look all ok. really weird...
