Ricoh Aficio 1075 Feed Issue
I'm working on an 1075 that constantly has jam code 8,9,10, & 12 (depending on which tray is selected) during multiple copies. If you do single copies, it jams infrequently. This started off as a very intermittant problem that is now almost constant. I have replaced/checked all feed units, registration section, wiring harness going to FCB, and the FCB. Any thoughts??

Duplex
Try testing the duplex unit, in paticular the cluthes may need to be replacedTrade like a tiger sleep like a baby -
I would increase loop or buckle amount and see if it helps.
If no change I would check sensors.
Check lead edge registration.
If it changes I would look at a bind or bad motor or clutch.
Isolate and replace or compensate.
I have also run into paper curl.
The paper should be curl down under the drum.
Curl up tends to follow the drums circle.
Just a thought.Why do they call it common sense?
If it were common, wouldn't everyone have it?Comment

Jam 8---1st vertical transport sensor
Jam 9---2nd vertical transport sensor
Jam 10--3rd vertical transport sensor
Jam 12--Relay sensor
You could swap drawer 3 feed station with feed station 1 and see how it jams. I think that it may be a problem with feed station 1, because all other drawers run by station 1, and with the 5 one-way bearings in there, a few of those may be hanging up. There is a TSB on paper drive motor adjustment for adjusting the belt tension on the feed station.
If the problems go away, I would look at drawer 1 one-way bearings, rather than the rollers or torque limiter.Bachelor of Science in Information Technology, Comptia A+, Comptia Network+Comment

I was under the impression that is was not really making it much into the registration section. Ok, is it then making it all the way out of the machine? You stated that you changed out the registration section, including motor-so I'm assuming that at least the reg. sensor is clean.
If it is making it through the machine, is it hitting the inverter section? How are multiple single pages-where it does not invert?
I'm thinking that, given the jam codes, the paper should not be making it to the fuser.
When it jams, is it stopping at the same place(s) each time? Or is the paper stopping erratically?
How does the machine run w/o the finisher attached?Bachelor of Science in Information Technology, Comptia A+, Comptia Network+Comment

Those codes can be misleading. They are saying where the paper stopped but not necessarily the cause.
As Imind has suggested, cause the copy to exit face-up, that way you dont use the inverter in the duplex unit. That clutches in that unit are prone to failure and give the symptoms described.
If yo get not jams that way, replace all three clutches in the duplex/inverter.sigpic

One thing to check is the registration mylars, they have caused me no end of problems in the past.
Open the front cover, look where the little "B" flap drops down when there's a jam, you'll be able to see one of those mylars. If it has a white strip down the middle of it, it's knackered and needs replacing. There are another two in the registration assembly but you'll have to strip out the registration section to look at them.It's 106 miles to Chicago.

Thanks for all the suggestions....It turns out that what I thought were good feed units were bad. I swapped them out with another set and she is up and running. I'll take the bad ones and go thru them and fix them. Thanks again.Comment

Great!! Glad that you found the problem. It definitely can be frustrating at times. There was an update on a few of the one-way gears (I think they are AB011490 & AB011491) Most of the later machines (Serial #) have these on them.Bachelor of Science in Information Technology, Comptia A+, Comptia Network+Comment

This machine has been prone to dev leaks from worn bushings which end up dumping dev all over the feed stations. This usually means a new set of feed stations.Comment

It's a refurb, isn't it, ART?
Hows the VW bus, anyway?
If it's the box I'm thinking it is check to see if it's one that was refurbed. Possibly has the wrong registration section in it altogether.
Anyway...it's time to think about it. All trays fail and I'll guess they all fail in the same place. Would that be just before or just at the registration section? The upper relay roller (shaft with the 2 big grey gears on it with B2 door) is driven by the bypass feed motor. Have you tried running a large number of prints feeding from the bypass tray to see if it jams in the same way? Probably won't as the bypass feeds paper directly to the registration rollers. However, if it does have issues jamming from bypass then maybe that's where it problem lies. I can't recall the linkage from the bypass motor to the upper relay roller (been seeing way too many Canons recently, Ricohs run reliably ;^)!!) but I don't believe it's clutch driven, more likely direct drive through gearing. Maybe the bypass motor belt is missing teeth, or the linkage between there and the upper relay motor has a gear missing teeth, etc., etc. You get my drift.
Otherwise, you could always try real estate again!!!!!VectorLinux---Check it out!Comment
