Vertical lines If black vertical streaks appear on the page, isolate the problem to copying, printing or
scanning and perform the following:
• If copying or scanning, check the CVT glass and document glass and if necessary
clean using a lint-free cloth. (See Document Glass and Constant Velocity Transport
(CVT) Glass on page 159.)
• If copying or printing, the surface (drum part) of the print cartridge inside the
machine has probably been scratched. Remove the print cartridge and install a new
one. (See Replacing the Print Cartridge on page 157.)
If white vertical streaks appear on the page:
• The surface of the LSU part inside the machine may be dirty. (See Internal Areas on
page 159.)
Background If the amount of background shading becomes unacceptable:
• Change to a lighter weight paper. (See Paper Supply on page 193 for specifications.)
• Check the environmental conditions: very dry conditions or a high level of humidity
(higher than 80% RH) can increase the amount of background shading.
• Remove the old print cartridge and, install a new one. (See Replacing the Print
Cartridge on page 157.)
•Use the Background Suppression feature in the Menu options.
Ton e r sm e a r If toner smears on the page:
• Clean the inside of the machine. (See Internal Areas on page 159.)
• Check the paper type and quality. (See Media Guidelines on page 124.)
• Remove the print cartridge and then, install a new one. (See Replacing the Print
Cartridge on page 157.)
Vertical repetitive
defects
If marks repeatedly appear on the printed side of the page at even intervals:
• The print cartridge may be damaged, run a few prints through the machine and if
you still have the problem, remove the print cartridge and install a new one. (See
Replacing the Print Cartridge on page 157.)
• Parts of the machine may have toner on them. If the defects occur on the back of
the page, the problem will likely correct itself after a few more pages.
• The fusing assembly may be damaged. Contact a service representative.
