    I am having trouble getting a good print. Here are photos from a 48" x 16" Pantone chart I printed as a test. The left and right edges are wavy and distorted. There is a row about a foot in that things get scrambled along. The #17 is black and it prints that plus a ghost #17 1/4" away in red. The swatches are all scrambled and goofy running down the print in that one area. The lettering at the bottom of that area is
    also all scrambled.

    Any ideas?

    Very likely an issue relating to the encoder strip, or it's sensor.

    We cleaned and cleaned and eventually replaced our strip and still had issues. Turns out that our VP-540 makes more overspray than most (according to tech) and the sensor was covered in ink. Tech changed it out and it's been fine ever since. That was at about 7-8 years old, it's 11+ now.

    Malkin above is correct. It is either the encoder strip or sensor is dirty. Clean them.
