Chapter C
Improving the print quality
If you are having problems with print quality, please do a test print first (Menu/Set, 4, 1).
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 the machine.
