Biz Hub C224e with DF701- scan glass assy jam?

[RandyW]

We were looking at 1 of these today. Our tech saw some sort of bump or crease on the tape like material on the scan glass assy where the originals pass over using the DF.

I was looking at the parts book for the C224e and it looks like you have to get the whole assy.

What does 1 normally look like? (we don't usually work on the Konica Minoltas). The paper was getting bent sometimes feeding in at the spot too. Rear part of the scan assy.

That is normal. Never had it cause a problem. More of a problem with the mylar guides in paper path tearing and causing issues.

If you're talking about A161R72300(A161R72311) Slit Glass Assy tape like part I will try to smooth it by file it. If the results are not satisfying you may need to replace this part.

Wanted to add I've seen that black mylar really bad on machines with 1 mil plus meters. You would think it would cause problems but never did. Don't think the originals even touch black mylar that much, if at all.

I'm a believer of leaving well enough alone unless a problem.

After 40+ years in this biz I've come to realize why "open a can of worms" !

Re: Biz Hub C224e with DF701- scan glass assy jam?

ok thanks.

I suppose the paper goes fast enough over the scan glass area that the tape would have to be pretty messed up to cause a problem. This machine has a little over 300k I think.

I was trying to look at the service manual for the C224e and then the parts book for the DF701. These mylars are kind of hard to see- to me anyway- in the manuals. Is there a part number
for them? Then I can look again at the manual.

I got an active solutions pdf for that machine too. Those are the tech bulletins?


unrelated but the same machine...they have a fax option in it. Do they need anything else added to be able to fax over the internet?

You may have to raise the doc feeder a little bit. It may be too close to the glass and you may see on the copy that it make a little bump or squiggle.

Had a call today with a DF701 and the black mylar was really bad. Confirmed the original doesn't even touch it and it's there to mask the exposure lamp and outside light. The original is fed directly onto slit glass and under white roller which presses it down onto slit glass. Point being it could be damaged and real ugly and have no effect at all with ADF jamming, etc.

Staples and paper clips are what tear up the black mylar, which then causes jams or torn originals because of it sticking up too high where the damage is. I've had good luck just taking an Exacto knife and carefully cutting a V shaped notch around the damaged area to make sure it's smooth so an original won't catch on the damaged area. I only cut through the very thin black mylar, leaving the very thick, translucent (what looks like HDPE) plastic showing. Just make sure the point of the V is on the left. I've done this many many times and never had to replace the assy. and never had any issues with copy quality.

Does the document reading roller/1 ever cause jamming? Was reading it is supposed to lift up. Seems to be 1 page goes through ok and then multipages is when a corner is getting bent up.


The original is ok I think up until the area near the A3CEPP1B01 White Sheet.1506938732714391786.jpg

Re: Biz Hub C224e with DF701- scan glass assy jam?

Bent corners is often caused by incorrect DF height (the mylar just right of the slit glass should fit down behind the ramp at the right of the slit glass, not above the ramp), or DF skew (same deal: mylar does not tuck in behind the ramp because it is not straight with the slit glass). =^..^=

I recently had one bend the back corner but only about 1/4" - 1/2" with a fairly low jams. After going through it several times and finding nothing that I thought could possibly be putting the originals in a bind, I blew it out with an air compressor at 90psi (heh heh). This worked, but I never found the culprit. I am assuming it was a hidden staple or something...

I had one jamming intermittently exactly like this and it was the rear hook of the 2nd side door, not latching completely because the customer was just pushing on the top/front to close it instead of firmly pressing it shut in the middle. Also, maybe something is bent not allowing the side closest to the hinge to fully lock the hook into place.

Re: Biz Hub C224e with DF701- scan glass assy jam?

we ended up adjusting the height some on the ADF and there was some black(?) mylar our guy said he had to adjust. Not the one on the scan glass assy...although he did cut that like one of the posters commented.

I have noticed that these document feeders are also cracking near the left hinge. A couple of signs that I look for are: 1) check the screws that secure the hinge to the ADF base there is usually one of them that is loose or won't tighten. 2) you can't adjust the ADF height. If nothing is working, I would suspect you have a cracked ADF base. While you're at it check the clear mylar that has been mentioned. you might want to change it. It's kind of a pain to do. Good luck
