DF3030 J003 & J053

[jonezy999]

Hey all,
DF3030 stops feeding originals in the same place every time. Usually will feed 5-10 sheets before the jam. Have replaced pick up roller, feed belt, sep roller. Replaced Pick up collar as it was broken. Cleaned all sensors and felts. All sensors work during free run. I have the modified feller holder bracket on order to hopefully sort out this issue.
Anyone else seen this issue? I know there is a bulletin regarding 003 jams and this feeler holder has solved it for me before, although I have mainly J053.

Tried the feed clutch?

Tried the feed clutch?

Was replaced a few months ago, nothing to say it's not at fault again though.

Does this customer do a lot of scanning?

No, nothing excessive. The machine is an MP3350B, so it is just a copier with around 90K through the ADF.

Have you tried replacing the torque limiter B8022255.

Re: DF3030 J003 & J053

Machine Ricoh MP2550b, 176000 clicks. Customer does some scanning, mostly prints to it with about 25% being copies made from the ADH.

Sorry I know this is an old topic, but I am having the same issues a described by the OP (found this thread using a search for J003).

He's what I've been taught about jams...
Friction Clutches (torque limiters) rarely jam in the exact same place every time..just the nature of friction and the random times it affects your machine.
Electro-Magnetic Clutches, generally work off of a timing / location sensor. And usually don't stop at the exact place each jam because the clutch is attempting to do its thing(engage) and is slipping or not working at all.

So if the jam is stopping in the EXACT same spot each time (as mine is) seems there's a sensor that is working only randomly (for my problem you can run any random number of originals through and it works fine...then it stops randomly during exit with the trailing edge sitting centered under the white exposure glass guide. Same spot exact each and every time it errors...J003. And after the error it tends to keep erroring out for a few tries, then like a magical copier fairy touches it, it takes off and works again for a while. Totally random...except for the exact place it stops each time it errors/jams.

Again sorry for exhuming an old thread but it was an exact match to my problem.

Re: DF3030 J003 & J053

We had this weird problem after replacing, clutch and modfied shaft ,and after much searching located the top release cover above the feed roller was warped, it so happens the customer was using a small laminater on top of the adf ...

Re: DF3030 J003 & J053

Cant remember but if you use sp mode and run the adf in free run simplex or duplex doesnt this bypass using the senors so you can easily test mechanical issue from sensor issue im not for certain but was thinking free run mode didnt use the sensors. Do that with a whole stack of papers several times and if they don't jam then you know its not mechanical.

The only think i can guess is the sensor on the underside by the white plate. Remove the 2 screws to take off the felt pad, clean the felt, then shine your flashlight in there and usually the sensor is also extremely covered in dust, i would guess this sensor because the trail edge of the paper has just passed this point when it jammed so the sensor is probably not seeing the end of the paper and causes it to jam.

Most of the time if the sensor is covered in dust it doesnt reflect light when the leading edge enters and jams at that point, when the felt pad is dusty it can reflect light even after the paper has left causing the lag jam.

Re: DF3030 J003 & J053

Yeah in free run mode it takes paper and does a simulated duplex copy. Did that time and time again no issues at all. Throw timing back into the equation and that's when I start getting the jams. I did notice if I ran multiple sheets through that it was almost always the last sheet that stopped on the exposure glass guide. Thought I had cleaned all sensor areas...maybe I need to check the one you mentioned again.
