■HRC Setting

When you select “HRC SETTING,” you can set the high resolution control (HRC). This is a special function that offers improved print quality of characters and graphics that conventional laser printers cannot attain with resolutions of 300 or 600 dpi.

Display Message	High Resolution Control
HRC =OFF	Cancel high resolution control.
HRC =LIGHT	Set high resolution control to the light level.
HRC =MEDIUM	Set high resolution control to the medium level.
	(Factory setting)
HRC =DARK	Set high resolution control to the dark level.

The following figures show jagged print with the high resolution control set to “OFF” on the left and clear and crisp print with the control set to “MEDIUM” on the right.

HRC = OFF HRC = MEDIUM

Fig. 4-5 High Resolution Control

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 information, 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.
