I’m getting good at solving printing dig negatives, but I can’t figure this one out. I have an Epson 3800 printer. I feed Pictorico through the rear feed with the front tray up and a “q-tip” stuck in the left side so that I don’t get Pizza Wheel marks.
I only print when I can get a good nozzle check and I’m getting good at feeding paper (a little away from right edge of feed slot) , and at preventing head strikes.
Here’s the problem:
I am getting what I figure a roller mark would look like 2.25 inches in from the Right edge of the Pictorico. It is 3/8 inches wide and goes the full length of the image, though I don’t see it in the black borders at the leading and final edge of the print. It prints out on my cyanotypes as two parallel lines with the area between the edges the same density as the rest of the image. The problem is more noticeable in mid-tone/light images and obscured in complex very dark images.
The problem mark does not align with any rollers I can see through the front opening. It seems to be on the printed side of the Pictorico.
The marks do not occur if I run a sheet of paper through (instead of pictorico) while keeping everything else the same.
I’d appreciate any suggestions on how to get this mark to go away. My alternative is to just make dark, moody prints, but I making a serious effort to lighten up a bit!
