    Re: MXM450N

    I have a few database entries:

    Misfeeds (jam code TRAY1). After rollers are changed jam code changes (jam code PPD_ST1), after running pre-perforated cardstock & repeated jamming. Tray #1 lower separation guide is broken at its front swivel. Remove the print engine. Remove these units: drum, developing, cleaning, registration. Flip engine upside down. Remove left cassette rail to install the tray #1 lower separation guide (PGIDM1892FCZZ).

    Misfeeds (jam code TRAY1). Customer has loaded used stapled packets of paper in tray #1. Load new, unstapled paper into tray #1.

    Misfeeds (jam code TRAY1). Customer has loaded paper folded over at the bottom of tray #1. Load new flat paper into tray #1.

    Misfeeds (jam code TRAY1). Paper krinkles in tray #1. The customer has removed the paper guide in front of the feed tire assembly in tray #1. Replace the paper guide (PCOVP1543FCZZ).
    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.

    Boy, that doesn't sound right. Tray 1 Jam is very specific to paper not leaving Tray 1...

    That's the point ,it's a bit weird but even if i use tray # 2 it will still jam with jam code ''tray 1'', could it be related to the drive unit ??

    The feed cassette is easy to swap out. Post a photo of the machine with the side covers open
