Fuji Javelin T9800 CTP II Banding issues

[Gregg Lazoff]

We have a problem with our machine showing 1/4 inch spaced bands on
the 250 screening…It happens in all colors and is very faint… We had Fuji out 4 different times to clean and try to fix the issue…It works for a few days ...then goes back to banding…All our other set screening seems to be fine… The machine settings for the lasers check out fine…I hoping someone else has had this problem… We seem to have the only machine is the world with this light banding issue… Help


Thanks

Dear Gregg,
Please find the best focus and fine focus for your plates. Recheck the drum speed and the work of the turbo fan blowing in the head. Also you can check the processor-fill it with fresh chemistry. One more thing is for high lpi to use fine mode of the machine-it will be slower but with best quality.

Dear Gregg lazof
about your problem did you clean hole (in surface of drum).it is for hold tight plate by vacum and very important should be cleaned.

do you know how you can found calibration position?it automatically detect and adjust best position of calibration sensor, board.
(command in service mode recording head test)
what is you light and focus,zoom value in printed job(1/4 inch spaced bands on the 250 screening)?
did you have this problem with another job(printed in another number of screening)?
waiting for your reply
