Chapter 7: Solving printer problems
Colored lines, streaks, or
smudges appear on the printed
page, or print appears blurred or
unclear.
Replace the photoconductors. If the problem only occurs when printing black,
you can replace just the black photoconductor and fuser coating roll. If the
problem occurs when printing one of the colors, replace all three of the color
photoconductors. See page 94 for more information.
Toner specks appear on the page. Replace the fuser coating roll. If it is not time to order a black photoconductor kit,
which includes a fuser coating roll, order a separate fuser coating roll
(P/N 12A1706). See page 95 for more information.
Toner colors the background of
