    DF701 pickup issue

    DF701

    not picking up paper very reliably

    the pickup wheels just spin on the paper without any traction

    I replaced

    A3CFPP6V00 Pick-Up Roller Assy
    A3CFPP7000 Gear Assy
    A3CFPP4G00 Cover Assy (sep pad)
    A3CFPP4H00 Roller Assy (sep roller)

    Still same fault

    If i put pressure on the shaft that pickup rollers are on it works perfectly

    Even putting pressure on the adf lid doesnt help and i also double checked the hooks that hold it closed.

    I not sure what else could be causing it to do this

    Wow! I must say you left no stone unturned and replaced everything possible. I have been replacing the ribbed pick up rollers anytime replacing the rollers. Because the pink rollers wear faster I was only replacing them and pickup's maybe every other time. Then I started to get imtermittent misfeeds / jams so now replace ribbed P/U rollers everytime. You covered that by replacing the whole p/u assembly. Was there a small washer then e-clip on the feed clutch / gear assy. If not I would put one on. I have seen some DF-624 & 701 have these washers and some don't. Only thing I can think of right now. If anything else comes to mind I'll post it.

    What jam codes? =^..^=
    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.

    One way clutches are spinning on the drive shafts!

    Take apart the feed unit and look at the shafts where the drive clutches are.

    Dress off the shiny chrome areas with a green scrubby pot scrubber, very fine 1000 grade sand paper or steel wool.

    One ways are the small white or black plastic thimble size units on the shaft that spin in one direction and lock and drive in
    the other direction.

    I ruled out the feed assy by putting in a 2nd hand one.

    i would have to be very unlucky to have grabbed another dodgy one with exact same issue from our scrap yard but i guess its not impossible

    Very common situation with this model.

    Have a quick look, easy to fix.

    Not obvious.

    Take apart everything off of the shafts.

    You will see shiny chrome surfaces where the one ways are slipping and not grabbing do to wear.

    Burnish areas with steel wool to get a "normal" surface again.

    You cannot see this unless you take it all apart.

    What the poster is saying is to scuff up the shafts where the one way clutches contact shaft. Anyone working on Kon/Min knows or should know this common issue with jamming. Started doing it with the Biz C253, etc.

    But not sure that's your problem. Think I read you replaced the whole feed assy with a new one and even tried another from scrap machine. I would rule out scuffing up the shafts if you tried a new unit and still jammed. A brand new assembly isn't going to need the shaft scuffed up. Does the new feed assy come with the white clutch on end of shaft?

    Did you swap the whole top cover from another machine? That would eliminate everything with rollers, clutches, etc.

    rrrohan, do the basics first and post jam code. When there's problem with paper jams error code ALWAYS is handy. In your case I'm with Grey those oneways are so cheap in both terms of quality and price. My friend is in habit every time he's changing rollers with them he change oneways in sight.
