Adjusting Print Density - Epson ActionLaser 1600 Reference Manual

If your check pattern is too heavy, change the setting to
LIGHT as dexribed in the foIIowing procedure; if it is too
light, change the setting to DARK; if you are printing gray
shading or screen patterns, change the setting to OFF.
To change the RITech setting:
1. Press the Menu button once.
2. Press the Item button until RITech appears on the display.
3. Press the arrow button until you see the setting you want
(LIGHT, MEDIUM, DARK, or OFF).
4. Press the Enter button to save the new setting, then press
the On Line button.
Note:
If you see the message RESET TO SAVE, press the Reset button
while you hold down the Alt button.
5. Reprint the RITech test pattern to see if the new setting has
improved the check pattern.
If the pattern still needs to be improved, you probably need to
change the print density setting. For a darker RITech setting,
make the print density lighter and vice versa. See the next
section, "Adjusting print density."

Adjusting print density

Note:
Do not change the print density unless it is necessary. Changing the
print density @cts all text and graphics, so check the new setting by
printing several pages with various kinds of text and graphics.
If your test print pages are too light or too dark, adjust the print
density as follows.
