Strange problem KM-8030

[Raymondd]

Hey guys,
This is a strange one...KM-8030 only jams when using the EDH paper exits machine and jams (finisher attatched j-81 without finisher j-60). This machine will run copies off of the glass all day long.
We have formatted the HDD, of course upgraded firmware, replaced main and engine pcb.

Any ideas will be greatly appreciated!

Jam 60 relates to the sensor locted between fuser and duplex, it actually sits underneath fuser exit, if this sensor is loose in any way secure it with superglue and put an extra turn on the actuator spring, hope this helps.

Thanks for the reply aabarnes1,

The sensor has been replaced twice. The problem is the 8030 will run copies from the target glass all day long. I can't get one out when using the doc feeder...

if printing does the same where it jams... then the problem is somewhere else
if printing does not jam
then try switching the doc feeder or sparing that then the boards that fit in the doc feeder...

and before you surprise us again... tell us exactly what you do with the doc feeder... is it single sided... doublesided and so on... make sure to do the same with the glass and printing... cann't fairly help you... if you don't fairly tell us whats going on...

I'm still trying to figure out what an "EDH" is. It's just a guess based on the J81, but that's a funny way to spell Document Finisher or DF-650. =^..^=

i just betcha she'll jam using 1 sided to 2 sided off the glass too. consider the eject mode difference between the feeder and the glass - odds are the feeder dumps face down and is using the duplexer and the glass just dumps face up. i would start with a thorough cleanin of the duplex and all the transport rollers to the join section (also clean the rear original sensor on the doc feeder (the one for legal/ledger) just to eliminate that) see if this helps any. gl

Thanks Elle,
That makes perfect sense I'll keep you guys posted. Blackcat EDH electronic document handler, minolta terms old habits die hard. Thanks again everyone.

Did you find the problem? What was the fix?

Solution-Feedshift Gate Pad

This one was a difficult one to find.

The foam sound damping pad on the flanged stop for the feedshift gate becomes sticky, due to the fuser heat and age. There is a new style foam pad, but simply removing the existing pad and adhesive works quite nicely.

Re: Strange problem KM-8030

Thanks Blackcat. I removed the pad and cleaned the residue and the problem went away.

My latest problem is a j83 everytime I power-up the unit. Opening and closing the top door on the DF clears the problem and the machine works great. Any suggestions would be greatly appreciated.

I don't think I've had J83 before:

J83

STPES

Paper jam at the siding drum (DF-650)

When the sub tray paper ejection sensor (STPES) does not turn Off within 1000ms of its turning On.

Sim 241 for STPES

1) Worn or dirty siding drum, 2) Defective STPES.

Actually, if I open and close the top door on the DF the screen says Call Service Center, and then if I completely turn the power off (0/1) and back on the problem clears and goes away. So the problem appers to be assocaited with using the Power down button on the control panel and is cleared when the machine is completely restarted.

Re: Strange problem KM-8030

You really need to call a tech.

There's more to being a tech than just standing near a copier. =^..^=

Re: Strange problem KM-8030

If you were servicing Tennessee I would call you; but I just paid $163.00 for the local Kyocera/Copystar tech to look at it, and Bubba didn't have clue, so after he used up his can of compressed air and was still scratching his head I mentioned your suggestion about the feedshift pad. He said he had already tried that, but after he left I opened it up and could feel the feedshift sticking to the pad. I removed the pad as you suggested and cleaned the residue and the problem went away. To his credit, at least he only charged me for one hour. So thanks again for the tip on the feedshift, but Bubba's not getting any more money from me. If I figure it out I'll post it to help the next guy.

Re: Strange problem KM-8030

I would check ALL the sensors on the the whole path of the DF650! and clean it with cottonbuds dumpened with ISO Propyl. Just don't scratch the reflective sensors!!

Make sure the exit sensors in finisher are checked twice!!

I had similar every now and then issue. I was just a bit unfortunate with paper. Also as we had a huge runs and it only appeared when fresh rims were put in the machine. When checked the paper, it felt a bit dump, although it wasn't producing waves or curvation on exit..it tend to slip every now and then. As a by product of this humidity I had some mist/dusty clung on the sensors. When cleaned,it came back in 20-30k instead of 2-5k. So I had 2 weeks of hell..as we had 12 machines pumping 120 - 150k each in 2 weeks.

Maybe worth mentioning the little nylon rollers above the huge roller in finisher, tend to have hiccups and it doesn't take long to clean them. Can sort out few delay jams in finisher.

hope it helps..
