Method 2
Use SIM46-21 to print the colo r balance adjustment sheet, and
Use SIM46-21 to print the colo r balance adjustment sheet, and
check each process (CMY) black patch color balance and the black
patch in order to confirm that the co lor 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 cop y mode.
(When the color balance target is DEF 1.)
If color balance or density is not satisfied, adjust the copy and
If color balance or density is not satisfied, adjust the copy and
printer color balance by SIM 46-74.

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 imag e correction (Process correction)
* Execute the high density imag e correction (Process correction)
forcibly. (SIM 44-6)
* The half-tone image correction is forcibly executed. (SIM 44-26)
Method
Execute SIM 64-5 to print the print test pattern.
Method
Execute SIM 64-5 to print the print test pattern.
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 dar ker level. T he density changing direction must not be
reversed. The density level of each co lor must be almost at the
same level.
