- Procedure 1 -
The goal of this procedure is to decrease the Tc (toner concentration) to allow proper
removal of remaining developer and achieve the optimum ratio of toner against developer
when initializing the new developer.
IMPORTANT: Make sure this "Procedure 1" is carried out before "Procedure 2".
1-1. Check the current Vt values in SP 3-001-001~004.

1-3. Print full-page solid patterns for the affected color(s) by referring to table 3 below
which shows the approximate required number of copies of the full-page solid pattern
according to the Vt confirmed in step 1.
If more than one color is affected, specify 2 affected colors when printing the solid
patterns to save time and paper, i.e. R (Y+M), G (Y+C), B (M+C).
* When printing the test pattern, black can also be mixed with the affected color, for
instance, K+Y.
* Work time can be reduced by using the copy function for the Copier model, and
printing the patterns from the Command Work Station using the calibration chart
(which allows you to specify the number of copies) for the Printer model.

1-4. Set the toner supply mode SP (SP3-301-001~004; Table 2) back to the default "0:
PID".
IMPORTANT
Make sure to set the toner supply mode (SP3-301-001~004) back to the
default "0: PID" before completing the procedure, otherwise toner will
not be supplied and this will cause problems.
