1. Change this setting from 1 to 20 at the time you install the new M development unit (G7823035) at
the same time.
2. It is recommended to use the new PCU and development unit when either is replaced on
machines produced in June 2004 or later. This is because if either of the older units is installed in
these machines, it is necessary to perform the SP setting changes explained in this section.
• If you perform the action for the black faint image (RTB RG071007), these SP
mode settings would be input.

1. Print out the test pattern of SP5-955-5 (1 dot Grid Pattern 0-1: 2 pages of A3/DLT or 4 pages of
A4/LT) in full color mode (SP2-917 test pattern on & send a color print job from the PC – see page 6)
2. Increase the settings of the following SPs by 1: SP2-950-4 and SP2-950-8.

4. Subtract 1 from the initial settings of SP2-950-4 and SP2-950-8.
