"image stretching"

[driall1]

We have a lino 560 with on line processor and Harlequin rip that has been a work horse of a machine. Lately it has been stretching the image as much as .25 inch in a 20 inch run. There are no noticeable lines in he image and the imager rollers have been cleaned and inspected. Does anyone have any suggestions on what it may be?

Thx
David

I'd rather suggest to check rollers pressure: cut a piece of film, push it between the rollers and lightly keeping the rollers stopped by hand, try to pull out the film...
If that was easy to do - "shrinked rubber surface" is my verdict.
The second case - Supply Cassette or even Film Roll winding.
Try it and good luck.

If the linearity is being inconsistent, it can either be a mechanical issue, motor, or an electrical issue that may just need an alignment. We can help with either one. Contact me off site or send me a private message and I can discuss it with you.

I have tried the rollers and they seem tight and the cassette seems to be operating as it should.

any other suggestions would be appreciated

either way Thx

are there any h/w or resolution settings that could have been altered or reset?
