Action Possible cause Solution
1 The toner supply is low. Shake the print cartridge gently to redistribute the
toner, or replace the cartridge.
2 EconoMode is on. EconoMode saves toner by
reducing the dot density. The effect might appear to
be a print-quality problem.
Turn EconoMode off.
3 The toner density is set incorrectly In the PRINT QUALITY menu, change the toner
density to a darker setting and try to print the job
again.
4 The media does not meet specifications. The
moisture content, conductivity, or surface finish might
not work correctly with the electrophotographic
process.
Try a different media type.
5 The transfer roller is defective or is not installed
correctly. If the transfer roller loses conductivity, it
cannot pull toner from the drum effectively.
Verify that the transfer roller is installed correctly. If
the transfer roller is damaged, replace it. See
Transfer roller.
6 The high-voltage connector springs are dirty or
damaged.
The high-voltage connector springs protrude into the
print cartridge cavity. Clean the springs if they are
dirty. Replace the springs if they are damaged or
missing.
7 The laser/scanner shutter door is not opening
correctly.
1 Remove and reseat the print cartridge.
2 Verify that the laser/scanner shutter door can
open correctly. If necessary, replace the laser/
scanner assembly. See
Laser/scanner.
8 The engine power supply is defective. Replace the engine power supply. See Engine power
supply.
