Need Help Roland SC-540 Skewing and "Ghosting"

[John C.]

Roland SC-540 started skewing the image during printing. The right margin of the print drifted to the left, so that after a few panels printed they were skewed toward the left of the media.

So far I've replaced the encoder scale/strip, the scan motor, the linear encoder sensor, and adjusted the carriage wire tension and performed every possible calibration listed in the 540 service manual.

Now I'm seeing "ghosting" (for lack of a better term) causing a slight "drop shadow" effect where there should be a crisp edge. I've added yellow stars on a photo a sample to show what I'm talking about.

Yellow stars have been added to the photo to illustrate the issue

Any help would be greatly appreciated

What does your head bias test look like? service menu/head rank/headadjust/bias/testprint

iff your print test is ok
try looking at the two outside pinch rollers
if thay are flat replace them as the media is starting to slip
as a test rotat the image and reprit if the gosting is in the same place i would be looking at the head alignment
