Cleaning the Printer
During the printing process, particles of paper, toner and dust 
can accumulate inside the printer. Over time, this build-up can 
cause print-quality problems such as toner specks or smearing. 
Your printer has a cleaning mode that can correct and prevent 
these types of problems.
Cleaning the Outside of the Printer
Clean the cabinet of the printer with a soft, lint-free cloth. You 
can dampen the cloth slightly with water, but be careful not to 
be let any water drip onto the printer or inside of it.
NOTE: While cleaning the inside of the printer, be careful not to 
touch the transfer roller. Oil from your fingers can cause print 
quality problems.
CAUTION: Cleaning the cabinet of the printer with cleaners 
containing large amounts of alcohol, solvent or other strong 
substances can discolor or crack the cabinet.
