Vertical or horizontal
streaks appear on the
page.
Replace the toner cartridge for vertical black
streaks.
Wipe the glass lens clean with a soft tissue for
vertical “white” streaks.
For horizontal streaks, see “White or black
lines or bands” on page 2-103 for more
information.
Toner smears or rubs
off the page.
• Replace the fuser. The toner is not being
fused. See “Cooling fan service check” on
page 2-81 for more information.

for copiers gives the best quality fusing.

card stock or labels, be sure you select the
correct paper type in the printer driver.
• Change the media texture setting. If the
setting is not in your driver, you can download
the correct Lexmark setup utility from the
Lexmark Web site at www.lexmark.com.
