BH363, C8101

[Hansoon]

Manual says: "Before reading pressure welding alienation mechanism trouble"
Hard to understand what the manual means.
Is this Japlish or can I not understand because my mother language is not English?
LOL

Never had this ADF error code. Any hints what to do please?

Something to do with that motor.
Never seen that code...

Re: BH363, C8101

check all connectors, do a sensor check as noted.
can you spin the motor by hand? maybe its all jammed up with a paper clip that is jamming up a belt.
take covers off and watch operation as it initializes at boot.

Think its to be able to remove jams when released.
open the image it should be good enough to read i hope.

Re: BH363, C8101

Seem like I am wrong. It releases so that the downstream drive is free to transport the paper.
One tough little DC motor.
Does a similar job to the solenoid on the exit roller pair.
DF-612 is probably the best and most reliable DFs KM has made.

Re: BH363, C8101

Were I to guess, I would say that the function of this mechanism is to take the pressure off of those rollers while the trailing edge of the original is passing. On some DF's you can get an image shift (front to back) towards the trail edge of the original, just at the moment the original clears the last set of rollers.

It may have been one of the best ADF's but also one of the loudest! The white sheet coming off bottom of ADF was perhaps the most common issue.

Re: BH363, C8101

I've only ever heard that error description in relation to the transfer belt, for the color roller retraction mechanism. I suppose the ADF rollers also retract so it sort of makes sense. The description really isn't very good though, as I don't see how that combination of words could be associated with the physical action of retracting or applying a set of rollers.

Re: BH363, C8101

Thanks all of you guys.

Still, I find “pressure welding alienation” a very creative expression. LOL

Hans

Yea it made me curious.
What was wrong with it? Then again there are so many DF-621's around it would be easier just to change it.

Re: BH363, C8101

Just came from the customer, didn't see the machine myself before. I noticed that the optical sensors were extremely dusty. They use the machine mainly as a scanner. Though I did not see any relation, I cleaned those, of course and made a hard error reset and everything was well.

Thanks gentlemen

Thanks for the follow up. Usually weird codes like that reset and you never see them again....

"Weird" indeed because when the machine came back to life after the error reset it showed in the beginning for a short moment Japanese characters in the display.

Someone was lost in translation from Japanese to English for sure. Plus there are some inherited codes from older engines I think. That's where service engineer takes place and should do some magic like Hans did

Btw Hans your back is seriously covered by most of experienced techs coming frequently here, you owe a considerable amount of good German beer to lot of folks

Have a very nice day/evening all!

Re: BH363, C8101

Thanks for posting back. A dirty position detection sensor makes a lot of sense, especially on a machine this old. =^..^=
