I just bought a DNP DS40 dye-sub (dye sublimation) printer on eBay for a little side project. I mainly was testing to see if my corners would fit on the print and noticed the left side printed very blotchy. About 2/3rds of the left side doesn't print solid. I've cleaned the print head with alcohol and the results didn't change.

Next I jiggled the print thinking it's not making full contact and my results did greatly improve. Now only the left 1/3rd is slightly blotchy. I attached a photo of the first version. blotchy dyesub prints


Looks like the printer may have been dropped and the head isn't aligned proper now.


Most common causes:

  1. Dirty printhead
  2. Wrinkles or creases in media that cause media to lift away from printhead
