print quality of characters and graphics that conventional laser printers
cannot attain with resolutions of 300 or 600 dpi.

The high resolution control has been factory set to "MEDIUM." The
"LIGHT" or "DARK" setting might be better depending on the selected
print density. Choose the best setting for clear and crisp printouts.
To check the printout with the high resolution control, perform the test
print with the Test button. For operation, see "TEST Button."
Lines in the test pattern are smoother if the high resolution control is set
to LIGHT, MEDIUM, or DARK. Choose an HRC setting and perform the
test print so that stepped lines become unnoticeable.
