KM3060 Doc-Feeder Jambs

[NeoMatrix]

G'day...

I have a KM3060 having problems with jambing in the Doc Feeder. {200K copies on counter}
The customer is out of town 35mins away.

I've been back a few times now to fix the bent mylar guides that feed the original down onto the slit glass.The customer has dragged the jambed originals backward out the entry of the Doc-Feeder on multiple occassions.

It appears that the left hinge doesn't sit down hard enough and the rear side of the doc feeder sits proud near the rear end of the slit glass. This causes a gloop type of noise as the original feeds through past the slit glass.

By pushing on the left hinge the noise disappears until the customer lifts the doc feeder again.
I have wound down the left hinge height adjustment 1 turn. This fixed the gloop noise problem for about a month or so, but it appears to have return along with the Doc-Feed original jambs. According to the customer.

I can run off 200 original feeds in the DF with no jambs.

Ideas anyone ?

Hey Neo, have you started with new rollers and the modified separation kit (which includes the cork pad)? Also check the pick up roller drop-down torque limiter spring, and tire holder. Both are known to break. What codes? J70, J71? 200K is a lot of originals on a DP-670. I wouldn't be a bit surprised if the hinges were excessively worn. How are you adjusting the DP height? =^..^=

RE: 200K that was the machine copy counter, not the DF. I have no obvious jamb codes. Everytime I go to the customer I can't get the DF to Jamb. I can run upwards of a 100 double side into the Doc-Box and nothing goes wrong. I might take your advise and replace the feed tyre and separation pad, possibly the entire left DF hinge. DF height adjust has a bolt and lock-nut under the back cover near the left hind; I turn that bolt counter-clockwise 1 turn. Tnx

The thing that I was getting at, is that there is a foot at each corner. You can shine a flashlight in the crack while closing the top. Each foot should just touch to machine top with the top closed. The other way I've done it, is to take a letter size piece of paper and fold it the short way to get two layers 4.25" x 11". Close the top with the paper between the foot and the machine top. Then you can adjust the height screw until you feel some drag on the paper. Either way works fine. Keep in mind that inevitably plastic frame document processors experience some warping. The best you can get is three of four feet properly adjusted. Make sure two of those three are at the left where the slit glass is. If you can get 4 of 4 adjusted perfectly, my hat is off to you. =^..^=

Best way to discribe it, is like a dragging sound, than there is a slight tap at the end with the original hits the slit glass guide. ::Analogy :: Drag a peice of paper along a desktop under school ruler(gloop) and then flick the end of the ruler on the stack of papers or pad. That's the best description I can do for now....

Re: B095 Is that on the Kyocera web site or in the TIL CD's. If that is the kyocera website which year and month ?

I think I know what sound you are talking about! And I'm sure if you look at some of the copies you make at 30mm you'll prolly have like a squiggly line of text or such...I haven't opened up the bulletin up above but if it's the one I'm thinking of there are mylars to install on the DF where the papers enters back into the feeder after going across the slit glass to help it along it's way...

Re: KM3060 Doc-Feeder Jambs

have heard this "gloop" noise a couple of times on km2560's when the paper passes over the slit glass. both times it was caused by the large screw that the left document feeder hinge latches onto on the machine. it had become loose and as a result the back left of the DF sat up too high causing the problem,

Re: KM3060 Doc-Feeder Jambs

Sometimes the left hinge needs replacement from wear - it just doesn't sit properly even adjusted fully.
