4 press ACC BUFFER TOO LARGE.... really??

[Don OReilly]

I'm having an error every time I try to expose film with the 4press

"acc buffer too large"

for some time, before I expose I have been using the utility to advance the film into the output cassette.
there I can see values like "LDM Pls", "TKM Pls", and "CSM Pls", all running close to the same numbers, until now. Now the "CSM Pls" value is much lower, about 1/2.

I have tried adjusting the cassette motor "Cass. Init. Veloc" from the default 45 up to 60, without any improvement.

I have watched the film advance with the door open, and I don't see a lot of extra film there, just a smooth feed.

what do you think?

Thanks,

Don

Hello Don!

please check all dolev ROLLERS.
It may be damaged or sticky?

Hi Vasyl,

all the rollers have been replaced over the past 2 years. I think I need to replace the encoder at the output cassette. Do you know where they can be found?

Thanks,

Don
