1)The max. density section is not blurred.
2)Patch C or D of each of Y, M, C, and BK is very slightly copied.
3)Patch for each of Y, M, C, BK
The patch density is identical between patches or not reversed.
The patch density is changed gradually.
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
(3) Printer color balance/density check
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) forcibly. (SIM

Method 1
Execute SIM
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.
