3. Printer-specific Adjustments
3.27 To Suppress the Unevenness on Images
Explanation
When the density of a halftone section looks uneven, this unevenness can be suppressed by changing the number
of screen lines.
With this adjustment, image quality in continuous copying can be more stable.
Procedures
* Perform the adjustment in accordance with the procedures below.
* Both the service technician and the user can use procedure (1).
* Only the service technician must use procedure (2).
(1) Change the roughness of images in 600 dpi printing.
Use steps (a) through (f) to change the setting value.
(a) Press [USER FUNCTIONS] on the Control Panel to enter the "User Functions" menu.
(b) Press [ADMIN].
(c) Enter the 6 to 64 digit administrator password. Press [ENTER].
(d) Press [GENERAL].
(e) Press [ROUGHNESS OF PRINT].
(f) Press [LOW].
<Note>
This setting applies to print jobs with 600 dpi. Set this to color and black printing, respectively.
Changing the setting displays the CONFIRMATION screen that asks whether you want to perform calibration or
not. Be sure to select [OK] and carry it out.
(2) Select [08 SETTING MODE] and change the value.
* This procedure makes the same setting as step (1) in [08 SETTING MODE].
Make sure to perform automatic gamma adjustment after changing the value.
Caution after the adjustment
When the low screen ruling is set, jaggedness may appear on diagonal or curved lines. In this case, check the
printed image and then switch the setting if necessary
