Real Time Process Control

During printing, 5 mm patterns are created outside the normal imaging area on the transfer belt, and the image density is corrected in the real time, to improve printing of solid areas. However, note that if the optional Imageable Area Extension Unit is installed, this process is disabled.

Normally, the real-time control is done once every 10 sheets, but it could be done once every 5 sheets depending on the density detection level.

The frequency depends on the following SPs.

• SP3-301-001: RTP Pattern:Set:Create Intrvl:BW
• SP3-301-002: RTP Pattern:Set:Create Intrvl:FC

To see the latest result, check the following SPs. If there is an error, the result will not be updated.

• SP3-300-001 to 004 RTP Pattern:Disp:M/A(Latest):Each Color
• SP3-300-001 to 004 RTP Pattern:Disp:M/A(Target):Each Color

When SC370-01/03 (logging SC) is issued, real-time process control is not executed. (However, when process control is executed, it is done so at longer intervals so that the density is maintained.)
