HP (Hewlett-Packard) LaserJet 4V Printer User Manual


 
Figure 5-4 illustrates three REt settings. Set REt so that the REt block is a
uniform gray with no vertical lines (see Image 2 below). Image 1 is too light
and Image 3 is too dark.
Harmonizing Print Density and REt Settings
Because print density and REt settings affect each other, it is wise to adjust
them at the same time.
To harmonize print density and REt settings:
1 Make sure printer resolution is set to 600 dpi.
2 Adjust the print density dial. (The center default position usually produces a
uniform gray REt block on the self test printout.)
3 Print a self test and examine the Resolution Enhancement block.
4 Set REt to produce a block as close to a uniform gray as possible, as shown
in Image 2 of Figure 5-4.
