SCR-SLCT Halftone process in Photo Printout mode
Lv.2 Details To set halftone process (error diffusion, screen 2 types) in Photo
Printout mode when making a copy.
Change the setting if the copy image has a problem with the initial
setting (Low screen ruling).
Select 0 (error diffusion) in the case of moire (suitable for character
reproduction).
Select 2 (High screen ruling) in the case of rough dots.
Use case When moire image or rough dots occurs on copy image
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range 0 to 2
0: Error diffusion, 1: Low screen ruling, 2: High screen ruling
Default value 1

Setting of error diffusion coefficient
TMC-SLCT
To set coefficient to be used for error diffusion process.
Lv.2 Details
Specify according to the level of granularity and dot stability.
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range 0 to 2
0: Small granularity/low dot stability
1: Small granularity/low dot stability (color mode), Large granularity/
high dot stability (B&W mode)
2: Large granularity/high dot stability
Default value 2
CAL-SW Set calibration control execute condtn
Lv.2 Details To set the condition to execute the calibration control.
Two types of calibration (patch detection) are available: one for
1/1 speed (for plain paper), and the other for 1/2 speed (for heavy
paper).
When 0 is set, only patch detection for 1/1 speed is executed.
When 1 is set, patch detection for both 1/1 speed and 1/2 speed is
executed, which increases the required time.
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Caution Do not use this when the machine is operating correctly.
Display/adj/set range 0 to 1
0: only for 1/1 speed, 1: both for 1/1 speed and 1/2 speed
Default value 0

VP-ART Setting of line art processing
Lv.2 Details To set outline processing for line art on scalable PDF.
In the outline processing, a binary image outline is extracted in the
field which is recognized as line art, and is converted into vector
data.
Specify whether to convert the binary image outline into vector data
or to recognize it as one line (as a thin line). For the thin line, the line
width can be specified.
Change this value when you want to obtain an output of a wide-width
line as one line rather than as an outline (when you want to prioritize
edit operation as a line rather than image quality).
Use case Upon user's request
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range 0 to 99
Default value 1
VP-TXT Setting of character vectorization
Lv.2 Details To set vector conversion processing for text on scalable PDF.
In the vector conversion processing, a binary image outline is
extracted in the field which is recognized as text, and is converted
into vector data.
In regular vector conversion, function approximation is not used for
small text because the image quality is not changed.
When the value is changed, function approximation processing is
executed for small text, which realizes smooth text although the
image quality is changed.
Change this value when you want to prioritize smoothness in small
text.
Use case Upon user's request
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range 0 to 99
Default value 1
C-PDL-T Setting of PDL gradation reference
Lv.2 Details To set whether gradation or density to be prioritized as the gradation
reference for PDL.
With priority on gradation (% of halftone dots), gradation is matched
with original on the shadow area although the maximum density
decreases. With priority on density, density is always matched with
original.
Use case Upon user's request
Adj/set/operate method Enter the setting value, and then press OK key.
Display/adj/set range 0 to 1
0: Priority on gradation (% of halftone dots), 1: Priority on density
Default value 0
