When the feed table stops, either manually, double sheet or mis-alignment, two or more pneumatic rods are fired down onto the sheet at the front...
How long the press rotates after an emergency stop will depend on press speed. To do a more accurate test using the emergency stop you could slow...
No you're not, it was me missing something :-) I'll have a think.
Check the operating manual regarding the perfector marking in straight printing: The freshly printed side of the sheet may get in touch with the...
Is the press an XL106 8P 4/4?
On a sheet that rigid I'd be running ALL units with impression on. I do agree though that I'd expect any marking to be more back half of the...
To add: The best way to guesstimate where to stick the foam on the super blue, is to get a printed sheet, inch it back through the press and when...
Oil and grease splats would appear as white spots in the image areas, and come and go in different places, every few sheets as the ink takes a...
It could be one of the axial fans underneath the transfer guide plates which supply the sheet travel air in between units. To check turn on...

Try min sheet size, max sheet size then desired sheet size. Poss with a power reboot too. Steve
A further thought. In job-prep when you've selected printing material as uncoated, measured the paper white and then confirmed the job onto the...
Nick Very puzzling. Same symptoms on both units? Been happening since installation? Running integrated roller set-up? Running standard inking or...
Possibly a small air leak from the compressor to the spray unit, as I believe that would disable auto mode, but manual mode would still work, with...
I'll have a bet it's the drive side... It'll be oil that's got into the pneumatic piston/valve. Later designs prevented this.
Tricky, isn't it! Just some musings, but hopefully some of the following may be of some benefit... One important setting you haven't shown is the...
