good day. my client complained that upon printing gray scale pattern as background image, half of it was no longer visible while the left part were almost as if it was shaded by pencil. i have tried cleaning the transfer roller on the image transfer belt assembly and the print head window but there are no effects. my developing unit, charging unit, and drum are new, the only part remaining that i have not tested was the second transfer roller. but when i perform test pattern, the output image is fine even on 100 setting on all colors. thank you for your help in advance.
