Sticky originals

[mikadonovan]

Hey, I hope all is well with everyone. Here is my fu$#ed up situation this week. I have some c4502's and 6002's in a law office, been there for years. The past few months I have received calls about DF jams, and I would clean and test, problem resolved. Or not. Apparently a stack of their legal documents would misfeed (multi sheet feed) when scanning, not always but enough to cause major issues. These packets that are jamming have come from a HP printer , and they stick together horribly. We (as in me and the customer) tested a variety of originals in the machine, and one thing became abundantly clear. The issue was with the HP printed documents only. Df sensors and rubber have been replaced on all the machines, and they work well. Except for the sticky hp printed originals. Slowing things down by setting the df to auto detect the size of each original, and run the problem DF originals short edge feed is the next, AND ONLY step I can think of. If anyone has run into this sticky situation before, I would love to hear your thoughts on the matter. Thanks.

did you also replace the separation roller pad?
check and add a little silicone grease also to the unidirectional gears

New reverse rollers, yes. One ways in the primary feed shaft have been cleaned. Again, all originals tried work fine except for the HP printed ones.

Turn this round onto the customer. It is the HP at fault not your Ricoh. Show them the Ricohs feeding plain paper OK then show them the HP prints jamming in the DF.

Then suggest they try different paper in the HP.

as Giuboss says, a pad can be added in front of the sep roller. (there is also a bulletin that now I do not have on hand), however we had this problem (j063) if I remember correctly, on a mp6503, I changed the spdf with another machine without saying anything to the customer, and what it was picked up mounted in another office on another 6503, morale, the new spdf had the same problem as the one picked, and his instead in the other office worked fine, in the end I decided to slow it down

I already showed the staff, and they participated in the testing. You ever notice the look on some peoples face as they are trying to grasp a concept and not succeeding? Some of that going around.

Re: Sticky originals

I went ahead and ordered the little pads, and the mylar mod mentioned in the bulletin. Thanks for the responses, tech warriors.

Yes, all the time, I feel your pain!

When I ever have any df problems I just always replace oem pick up roller, feed belt, belt roller {with bearing} reverse roller and limiter strip down df to get to all sensors blow out completely. If its multi feeding also check to gear on shaft for reverse roller they split good luck

Re: Sticky originals

Mika, a quick question, by sticky do you mean actually sticky to the touch or static cling?

Sticky as in will not separate.

Re: Sticky originals

I programmed the machine with a "sticky originals" preset on both copying and scanning running SEF and mixed mode. The packets are now feeding with the grain and slowed down a little. Testing this morning was good, looks like everyone is happy. Thank God. It has been years since I was this stressed on a repair. I might be getting too old and losing the right mindset for this shit, I dunno.

Re: Sticky originals

Have you asked them if they use original HP toner?
