DOUBLE PRINTING

Hi friends, I need your assistance regarding an Agfa drystar 5302 printer. A message of warning prints after every printed film with images sent from the Modality , which makes a full pack of 100films waste 50%. The test film is ok,the calibration of the densitometer is ok. There is no artifacts on the printed films .I looked at the TH, no problems I have upgraded the software, replaced the Tyndal Board as well, but the challenge still persist . Any idea or hint as to resolving this will be of great help to me. Thanks in advance. Note: the film currently in use is DT5B
