Method 2
Use SIM46-21 to print the color balance adjustment sheet, and
check each process (CMY) black patch color balance and the black
patch in order to confirm that the color balance adjustment is
proper.
Use SIM46-21 to print the color balance adjustment sheet, and
check each process (CMY) black patch color balance and the black
patch in order to confirm that the color balance adjustment is
proper.
If the color balance of each patch of the process black (CMY mixed
color) is slightly shifted to Magenta, it means that the adjustment is
proper. If the color balance of the adjustment pattern printed in this
mode is slightly shifted to Magenta, it is converted into the natural
gray color balance by the color table in an actual copy mode.
(When the color balance target is DEF 1.)
If color balance or density is not satisfied, adjust the copy and
printer color balance by SIM 46-74.

(3) Printer color balance/density check
MEMO: Before checking the printer color balance and the density,
be sure to execute the following procedures in advance.
* Execute the high density image correction (Process correction)
be sure to execute the following procedures in advance.
* Execute the high density image correction (Process correction)
forcibly. (SIM 44-6)
* The half-tone image correction is forcibly executed. (SIM 44-26)
Method 1
Execute SIM 64-5 to print the print test pattern.
Execute SIM 64-5 to print the print test pattern.
NOTE: When the PCL or the PS printer function is not provided in
case of GDI printer, this method cannot be used for check.
Set each set value to the default and press [EXECUTE]
key. The print test pattern is printed.
Set each set value to the default and press [EXECUTE]
key. The print test pattern is printed.
The print density must be changed gradually from the lighter level
to the darker level. The density changing direction must not be
reversed. The density level of each color must be almost at the
same level.
Method 2
When the PCL or the PS printer function is not provided (GDI
model), use this method for check.
Use SIM 67-25 to print the color balance adjustment sheet and
compare each process (CMY) black patch color balance and the
black patch to check the color balance.
