Our No.4 has a inking issue at approx 4 inches into the roll forward. what happens is a slight “jump” is felt and a faint reduction in inking of the plate for approximately 1/64th or smaller. results in a line that appears on the printer piece in the form of a lighter print.
I have cleaned all of the gears to insure no debris in the channels and rollers. I do not feel the “jump” at the end of the table.
Do the guide wheel order the rails need to be riding the top rail or the bottom rail?
