Avantra25 - problem with stacking film in output casette
we have problem with stacking film in Avantra 25 output casette. It seems as the core which grabs the film sometimes does not spin much enough to roll the film on it properly. Primarily we thought that it is problem of bad friction between output casette roll and driving motor roll, but it is not the case.
Could anobody help us to solve the problem?
If you have good contact with the Cassette and the Drive wheel, then it may just be the age of the motor. It does not have enough oomph to drive the cassette at the proper speed. The cassette may also need an adjustment of the clutch.
If you are able to stop the Motor Wheel touching yoir pointer finger with a small force - that's a Motor aging problem (carbon brushes wornt-out) and it needs more DC current to be driven. The Motor is not repairable at normal circumstances.
The second issue could be a SDM board problem (L298N chip).
The third - if the Motor OK - checK the T/U Cassette
You need a visit of the Serviceman to figure out what's happened and to fix the problem.

Thank you for the clues. One have to press the wheel pretty firmly to stop it. We observed loading of the film into casette with opened lid. Not every time the clutch grabs the film properly (film pass by) or if grabs properly does not wind film tightly. It suggests more the problem with electronic. Could it be the problem with the optical sensor which reads the revolution of casette core or rather with SDM board problem (L298N chip)as suggests AGFA-Vlad?
The problem is that here in Poland Agfa is pretty reluctant to service CTF any more and claims the cosmic fee.
Therefore we are looking for other means to solve the problem. Perhaps some service manual could help us to clear out the problem.
I'm waiting for other suggestions.

vogar,
you have to adjust the Cassette clutch spring for good greep of Media.
Just be sure the Reflective bar on the T/U Cassette wheel is still on the place and comletely DOWN position when clutch leaps are fully OPEN. That's for proper optical sensor reading.
I've met the issues when set-screw on the Cassette Wheel was loosen and the clutch missed the film output slot.

Thank you for the suggestions. However I do not understand what means adjusting clutch spring. The clutch lips work gravitational. The only two springs which I see in cassette are:
one to open cassette slot and another one to change the friction on clutch bearing. That spring we have tried to adjust in both direction and it seemed to have no effect. Reflective bar on the cassette wheel is in top down position when clutch lips are fully opened and we have notices that they are fully opened in the angle of about 15 degrees from top down position of reflective bar.
We appreciate to get more suggestions how to solve that problem.

HI,u can u using same as SDM board test it,if as same as problem,then I can comfired SDM board not problem!And pls tell me what error code,I can help u solve it
If I only knew how to get into the service procedure from the panel. I know how to get in SelectSet5000 but unfortunately not for Avantra25. Any info would be appreciated.
sorry,u cannot get into service procedure from the panel,it is not as same as ss5000,get into service procedure from the panel must from other Avdiag software puls test cables
It is pity, that we cannot perform any test procedure by ourselves. We do not get any non specific error code. Only the standard one - number 6 film jam.
