I have an HP T1100 on site. Whenever they print a certain files/s, banding happens when it reached the center of the paper. I have tried paper advance calibration, calibration of the printhead, cleaning encoder strip, shaft etc, Same thing happen, and banding happens on the exactly same location. If i print other files, it is printing well. If i print internal demo page, it is working fine as well. I tried to print the very same file in our shop machine, HP T1120 and exactly the same kind of banding happens. I cant totally tell that it is a file problem, because if i print the same file on another HP plotter like 4000ps and 1055CM, print is OK, no banding happening.
Have anyone experienced this?
