[Jamming] Rcoh MP7503 and MPC 5504ex with sadf

[danne@zersoft.se]

Hello !
Having some trouble with the SADF, for those of you that never heard of SADF, it is a Df that is scanning both sides of a document simultaneous.
Scanning speed is about 180 pages per minut
Now the problem. There is doublefeeding accuring often, and occasionally missfeed.
The document they scan is of varius quality.

Meaning that the customer have to check each scan so every page is in the job.
We have replaced all the roller and belt in the df, does not work, so wear and tear dosnt seems to be the case.
There are two sensors in the lid and cleaning them works sometimes but not Always.
Our supplier has mounted ESD-brush on the df, but it dont seem to help.

I think that the speed is the problem.
Is there any way to reduce the speed without increasing the resolution. The customer must have 300 dpi.
Or has anyone any idea what to do ?

If there is a large volume of scanning, the shaft from the pickup assembly gets faulty (attached to a 1 way bearing). In lower models (MPC 3501) the shaft attached to the clutch gave me this problem.

Are you saying this is happening on 2 different machines?

Yes on Mp 7503 and Mpc 5504ex, well Mpc 5504ex with the SADF, to complicate things, we have about 600 mfp in our Environment and aproxomatly half of them has this problem. Could be that the working half a.) dont report the error or b.) dont us the scanning as much. So to clarify this answer, yes the problem occurs on about 300 mfp of two differnt types. But i Think the SADF is the same for both.

Ricoh is working on this issue, probably getting 063 jam codes ?
Try using an AF032080 or AF032041 tire, you will have to pull off the old one and use the original hub since it's wider

What are the model numbers or product codes of the document feeders?

Are there any jam codes stored?

Re: Rcoh MP7503 and MPC 5504ex with sadf

How often does this issue happen, once per 100 scans once per 1000?

Did you replace the touque limiter with the friction roller?

Not sure if SDF has this but ADF 3090, have had probs with exit actuator getting lazy causing inter jams, also there is a modified lid and feed pickup assy for this model

First off, get your nomenclature correct. SADF stands for Semi Automatic Document Feeder. What you have is a SPDF, Single Pass Document Feeder.

Double feeding is more often than not a bad torque limiter for the reverse roller.

precisely correct what mention above. is most your originals are below 80 gsm like receipt? that even a proper shuffling wont help?

If your machine has an SP6901-1 Set it to 1 from zero. It allows higher stackability which slows down the adf a little to eliminate the Jam 63 separation jams. Also we have been taking the old reverse roller hub (Black) and putting the AF03-2080 Rubber on that Black hub with great results, no need for spacers because the black hub is wider than the blue hub the 2080 tire was on. Also ive been trimming the highest mylar that sits on the reverse roller down a little and that has worked great too. I've even removed them without any issue. I think that mylar sits too high allowing the paper to go over the reverse roller causing the jam 063. There is custom firmware for the MP6503 that slows down the adf and it works also, but the SP6901-1 needs to be 0 not 1. With these steps all machines we have had the problems with have stopped. Have a good day!!

Lets start with the jamming and double feed, it occurs approx. every 5 scanning. A scanjob is about 100-150 pages and mainly 80 gsm paper, but as it is an court there are sometimes handwritten pages in the scan job.
Torq,pickup,sep and feed belt are exchanged at least three times. The machines where installed in September 2018, and the problem occurs on two machines.

The originals are stored in folders some plastic and some is paper, some folder is wrap around the original.
We have mounted antistatic brush but it don't seems to have much effect.

We are scanning A4 R, shortside first and it seems that there is lesser jamming, as mentioned every 5 job or so.
Using "mixed originals" as standard
But i would like to slow down the scanning speed to around 100 ppm to see if that helps.

Do you mean to use paper tray sep roller as a DF sep roller?

Re: Rcoh MP7503 and MPC 5504ex with sadf

Yes, that would be correct, AF032080 is a blue paper seperation roller.
There was new DF firmware released yesterday from Ricoh and the Read Me mentions DF 063 jams, it was released for the following models:
MP 6503/7503/9003
MP 4054/5054/6054
MP 2555/3055/3555/4055/5055/6055
MPC 6503/C8003
Pro C5210/C5200
MPC 6502/8002
MPC Pro 5100/5110
MPC 4503/C5503/C6003
MPC 2004/C2504/3004/C3504/C4504/C5504/C6004
MPC 3004ex/3504ex/4504ex/6004ex
