Hi all,
I’m working with an SP20 and after I run through a print to the end of the bed and roll back to the feed board I hit some resistance about 6 inches before returning the cylinder the entire way back. Here is a video: IMG_0760
I’ve checked the screws and bolts I can see but cannot figure out what is causing the issue. Any help is appreciated!
Thank you,
Laura
No apologies needed. I’m sure someone else will have the same issue. Documenting problems is what this forum is all about.
I first tried oiling the areas around the cylinder eccentrics and the bearings and areas around the trip assembly and the problem seems to be solved. After a couple of prints it’s running really smooth. Apologies this was such an amateur error, but thank you so much!
Try shifting the print/trip lever to trip then continue on to the feed board.
There are a few different causes for this:
-lack of oiling can make the cylinder eccentrics not shift easily
– trip plungers on the side of the bed next to the ink drum gunked up, see sheet 244-A
– trip roller is missing
– trip spring is broken, the serial number determines whether leaf or coil spring is used.
Does the impression cylinder look to be at an angle in the carriage?
