I recently had the form rollers on my SP-20 recovered and I’m having trouble getting a decent print out of them. The short version is that my printing is slurred. The detailed version is that, if printing a line of type that’s parallel to the gripper bar, the rollers will print heavy towards the top and bottom of the line and leave the center fairly ink-starved. The ends of the line might also be slurred with the letterforms looking as if they’ve being dragged slightly downwards. I figured that the fix would be in adjusting the roller height but that doesn’t seem to work. I’ve checked my packing as well. I’m starting to suspect that the problem may be in the finish of the rollers. The service that recovered them talked me out of a high gloss finish and instead advised me towards a “matte” finish.
My questions are: Can roller finish cause this sort of slurring, and, what are the best specs for recovering form rollers on an SP-20 (especially those to do with finish)?
