Has anyone seen this before?

I am resurrecting an old sc-540 and I know it needs alignment but before I do that can anyone tell me why I'm getting over spray way out to the sides and there are two straight lines going right down through the words of the report, actually more than that but just the two showing in this picture. Since this report is generated by the machine no profiles or other things should come into play so do you have any ideas? Head or head board?----- help please! tom

Overspray and the lines could be from a bad head or one with deflected nozzles. Also the lines and overspary could be from the encoder strip (clear plastic piece the head runs along).

I would do a nozzle check and see what it looks like if you have missing nozzles or nozzles that are spraying on top or close to one another that would be a sign of deflected nozzles which will give you the overspray problem for sure. you may be able to fix them with head soaks and cleanings but if not then youll need a new head.

I am a Mimaki guy but also an electronics guy and honestly all of these printers are very similar.

Good Luck

Would a dirty head make the 2 vertical lines in the text?

Perhaps, static or a dirty encoder strip.
