Description:
potential for smeared print. Smeared print is typically noticed first in
heavy black or graphic areas, usually at the right-hand side of the
media. More specifically, without magnification, blotchy areas of toner or
fuzziness are visible around characters. A coating on the transfer roller
and a specific current value applied to the roller induce this print
anomaly.
Solution:
HP has implemented an uncoated transfer roller and
increased the current to the transfer roller via the DC controller printed
circuit board (PCB). These solutions appear to have resolved this print-
smear defect. After verifying the serial number range and the print
defect, replace the transfer roller and the DC controller PCB.
