New ARM455 doc feeder has trouble picking up las page in a stack of documents when copying or scanning. Adjusted sep pad and occasionally double feeds paper in stack but now can pickup last page in stack. If I return the sep pad to its origional position-no double feeding but last page again jams frequently. Suggestions?

Re: Brand New Sharp AR-M455 doc feeder trouble
how do you adjust the sep pad? That machine hasn't been new for 5 years. -

Add an extra rap in the timing sensor arm spring. it bounces.Comment

Re: Brand New Sharp AR-M455 doc feeder trouble
bent the flat metal piece behind the sep pad back just a hair to reduce tension......I know, I know, not a great way to try and fix a doc feed issue....but there is no adjustment. That machine is new and was purchased 1 month ago from Nuworld. I'll order a new sep pad assy but don't think it will fix the problem because the feeder has almost no miles on it. Sensor flag not causing the issue either. The paper buckles at separation causing the jam but only on the very last page and very frequently. We work on a lot of these feeders and they have been pretty reliable. This one I guess was bad out of the box.
Thanks for the replies. Much appreciated.sigpicAnything can be made to work if you fiddle with it long enough- San Diego Copier Repair.comComment

Re: Brand New Sharp AR-M455 doc feeder trouble
Have you tried downgrading the separation pad to the type in the EF1 (on the AR-450)?
I've had very good results. I was setting up these machines when they were new, and we were getting DF calls within a week of placement. Sean and I lined up an AR-450 next to an AR-455, and piece by piece identified the differences. I seem to recall it being about $50 in parts, and within a few weeks we were doing it on setup.
This thread has the details:

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.

Re: Brand New Sharp AR-M455 doc feeder trouble
Just for clarity, the "blackcat" version was being used 5 months before the original bulletin and is similar but not exactly the same. I didn't much care for the Sharp mod parts and only installed two kits before reverting to the original EF1 parts.

Re: Brand New Sharp AR-M455 doc feeder trouble
Update : Thanks for reminding me The blackcat mod is not the same as the techpub I posted. Tried the mod in the techpub and no progress. Will now try the EF1 parts you recommended.
Your blackcat mod------------"These are the parts required to downgrade the separation:
PSHEZ4847FCZZ Separation Pad Only
MSPRT2864FCZZ Separation Spring
LPLTP5747FCZZ Separation Plate
MSPRP2832FCZZ Leaf Spring
PSHEP4848FCZZ Mylar
PSHEP4878FCZZ Mylar
The various update kits never did return to the original tried-and-true EF-1 separation. If you are not familiar with the older separation, the parts stack up as follows: Bracket, Leaf Spring, Thick Mylar, Sep Pad, Thin Mylar, and Screw. The rest is pretty much self explanatory."Last edited by blazebusiness; 01-10-2012, 03:56 AM.sigpicAnything can be made to work if you fiddle with it long enough- San Diego Copier Repair.comComment

Does this mean success, or failure, or somewhere in-between? =^..^=If you'd like a serious answer to your request:

Re: Brand New Sharp AR-M455 doc feeder trouble
Failure-No change at all....still scans a 40 page document and sometimes you get 38 pages or 36 pages that scan to the computer due to pulling 2 pages at once. It's certainly a problem with separation.
Also, the dspf mod in the techpub was installed standard on this unit ---- no mod needed. The complete sep assy for the EF-3 is available as an assembly now - Part# CPLTM5746DS51 and backward compatible with the older EF-1 feeder. The only difference between the modified new sep assy and the old style EF-1 sep assy is the addition of spacer LPLPT7040.
So , I'm stumped as to what to try next. Current firmware installed. DSPF mod done. Sharp is a new copier sold just 2 months ago - with almost no miles on it with the EF-3 randomly feeding 2 sheets at once when scanning to the computer so the customer is missing a page or two of the scan. The same jobs scanned from their Konica C550 scans with no missing pages.Last edited by blazebusiness; 01-10-2012, 04:40 AM.sigpicAnything can be made to work if you fiddle with it long enough- San Diego Copier Repair.comComment

Re: Brand New Sharp AR-M455 doc feeder trouble
Hi
just to let you know there was a modification and a new sep pad assembly can be ordered, usually corrects issue, have 300 of these in my fleet and seen this a couple times.
Also on about 35 models i had to replace the adf wiring harness, as insufficient power was actuating lift gate solenoid in the top cover harness replacement have solved many of the issues.
also you can cut off the sheath over the adf to mfp wiring and check for damage on a brown wire, ie white line fold bend issue
pain in the ass job estimated time if you have never done one 2 hour minComment
