Improving the print quality
C
If you have a print quality problem, print a test page first (Menu, 3, 2, 3). If the printout looks good,
the problem is probably not the machine. Check the interface cable or try the machine on another
computer.
Note
You can resolve a print quality problem by replacing a toner cartridge with a new one when the
LCD shows the Toner Life End message.
