ryobi 2800 cd xl- plate to blanket adj. ?

I'm not getting proper squeeze on the drive side between the plate
and blanket cylinders. Causing issues when running linen stock and
eps.
Any suggestions?

What is your blanket packing? Is your blanket wore out or have low spots?

 

Bill, I'm sure it's not the blanket. Running a 5 ply .101 with .010 packing under.
Even with a brand new blanket I have the same issue.
When I ink up the plate solid and hand roll the press through an impression
cycle, I get excellent transfer on the op side but spotty, light transfer on the
non-op side. I'm thinking it's just a minor adjustment but don't know what to
adjust.
The operators manual is no help at all, says to contact authorized ryobi service.

P.S. I have striped the rollers. They're fine.

Thanks, Dave

 

I would try to look at either the bearing or the bearing housing on the blanket cylinder , you should see it in your parts book. It is possible that at some point in time the press had encountered a rough jam-up. There should be three screws which go through the side of the press to hold the bearing housing. If there is any slack in the holes , the screws may have shifted during a jam. It only takes a little movement to loose a few thousandths on that side. That may be where you are loosing image...??

 

There may be a problem in the master cylinder gap control, a possible bad roll pin or wore bushing? Hard to tell without actually checking each part. If you have a few minutes here and there, try to look at the linkage from one side of the press to the other, make sure movement occures at the same time on each side.
