Print quality—random marks
Service tip: The primary cause of random marks is due to loose material moving around inside the
printer and attaching to the photoconductor, charge roll, or transfer roll.
Print quality—blurred or fuzzy print
Blurred of fuzzy print is usually caused by a problem in the main drive gearbox assembly, alignment
assembly, any feed roller, or in the transfer roll bearings or transfer roll. Check the gearbox assembly
for correct operation. Check the transfer roll for binds or a contaminated shaft or bearings.
Blurred print can also be caused by incorrect feeding from one of the input paper sources, paper
trays, duplex option, or envelope feeder.
Check the high voltage contacts to ensure they are not bent, corroded, or damaged. Replace as
necessary.
