   TROUBLESHOOTING

Improving the print quality

If you are having problems with print quality, please do a test print first (press the 

Set

 button 3 times).

If the problem appears on the printout, then match it to one of the examples below and follow the 
recommendation. If the problem does not appear on the test print, please check driver settings and the 
interface cables as the problem may not lie with printer.

You can resolve a print quality problem by replacing a toner cartridge with a new one when the toner 
indicators start blinking or the LCD shows the 

TONER EMPTY

 message.
