(Meaning of the service color balance target gamma data and the
purpose of registration)
This procedure must be executed only when the color balance is
customized with SIM 46-21. If the color balance is not customized,
this procedure is not required.
After completion of the customized color balance adjustment (Man-
ual) with SIM 46-21 according to the user's request, use SIM 63-7
to register the service color balance target data by using adjust-
ment pattern that was printed in this mode.
By this procedure, the service color balance target is revised.
It is recommendable to keep the printed adjustment pattern with
SIM 46-21. This adjustment pattern can be used to register the
same color balance target to another machine.
It is also useful to register the service color balance target data.
Do not fold it and keep it under the circumstances which protect it
from discoloration and dirt.
The service color balance target data are basically registered
immediately after the color balance adjustment (Manual) with SIM
46-21.
If a considerable time has passed after completion of the color bal-
ance adjustment (Manual) with SIM 46-21, the color balance of the
adjustment pattern at the time of adjustment differs from the color
balance of the adjustment pattern printed after a considerable time.
Never use such a pattern for the adjustment.

abnormal.
In that case, the registered service target data for the color balance
