Printing is smudgy.

If “Replace Color PCU (Type A)” or “Replace Black PCU 
(Type F)” appears on the display, replace the photoconductor 
unit.

See 

If the paper is creased or curled, prints may smudge. Post-
cards are especially prone to curling while being printed on, 
so make sure they are perfectly straight before loading them. 
Straighten them if necessary.

Try reducing the print density. To adjust the print density, 
press the {Menu} key on the control panel and select [Image 
Density] from the Maintenance menu.

See 

.

Prints have smudges on the 
back.

Automatic selection of paper size and feed direction may 
have been canceled, a specific paper size selected, and then 
paper with a different size and feed direction loaded. Enable 
automatic selection on the control panel. Alternatively, load 
paper with the same size and feed direction as the settings 
on the control panel.

See 

.

The paper size and feed direction settings on the control pan-
el may not match the size and feed direction of the paper in 
the bypass tray. Make the settings that match the size and 
feed direction of the paper in the bypass tray.

See 

If the print area exceeds the paper size - for instance, when 
producing A4 prints on B5 paper - subsequent prints may 
have smudges on the back.

Printing is entirely patchy.

If “Add Toner XXX” (where “XXX” is a color) appears on the 
display, replace the appropriate color toner cartridge.
