Function/[Setting]
Switches on/off the setting that corrects
uneven images generated during 1200 dpi
printing.
[0~1/1/1 or 0] 1: On, 0: Off
Unevenness may appear in dot patterns or
narrowly spaced horizontal lines, i.e. some
areas may appear lighter or darker than
others.
Adjusts the amount of correction for uneven
images generated during 1200 dpi printing.
[–20~+10/–8/1]
Switches on/off the setting that corrects
uneven images generated during 1200 dpi
copying.
[0~1/0/1 or 0] 1: On, 0: Off
Adjusts the amount of correction of uneven
image generated during 1200 dpi copying.
[–20~+10/0/1]
Adjusts the pixel density. Required for design
check, beam pitch adjustment for the test
pattern, etc. DFU.
Allows shading detection if FCI (Fine
Character Adjustment) smoothing is on. With
this SP switched on, photos and painted areas
are detected, and FCI is not applied in these
areas. FCI is used for outputs in printer mode.
[0~1/1/1 or 0] 1: On, 0: Off
Allows setting a parameter for binary edge
processing for the printer application with FCI
switched off. The value for this SP is enabled
only when the printer is initialized. In all other
cases, the data registered in the software are
enabled. This SP allows adjustment of image
quality if the desired effect cannot be achieved
with the default settings for edge processing.
However, some settings could cause defective
images on white paper.
