2.5.2 Image-Stabilizing Control
Controls for providing stable print quality are described in this section.
2.5.2.1 Process Control
To provide a stable print quality, the parameters required for creating a color image
should be corrected on a timely basis.
The control of whole print process including the correction of parameters is called
“process control”.
In the process control, toner patches for process control are created on the belt surface.
The patch sensor detects the patch density to execute the following controls:
High-voltage setting values for the electric charger and the developer
The power of the laser beam
Gradation correction (The data acquisition and transmission for the gradation
correction is executed on the engine controller side, and the actual control is
carried out by the main controller.)
EXECUTION TIMING
When the power is turned on for the first time after purchase.
When the photoconductor unit is replaced with a new one.
When the toner cartridge(s) is replaced.
The printer executes the control when it detects the replaced cartridge(s) is
different from the previous one(s).
When the printer judges that target values* for the control need to be corrected
based on the status of cartridges.
NOTE*:
The target values to determine the exposure power and the DC bias.
