(6) Main scan magnification adjustment
• The main body is mounted with only one IDC sensor and therefore unable to make the main scan magnification adjustment or calculate
the skew amount automatically. The main scan magnification adjustment is therefore manually made using the menu on the operation
panel.
• The adjustment is necessary when the adjustment value is cleared, such as when the PH unit or the backup board is replaced with a new
one.
(7) PH unit temperature detection control
• The temperature inside the PH unit is measured at intervals of 30 sec. by the PH temperature sensor mounted in the PH unit.
• The detected temperature data is recorded to form part of the environmental information data and used for controlling, for example, color
registration, 1st transfer output determination, and transfer roller cleaning.
(8) Image processing
• The following image stabilization functions are available as they relate to the write section. For more details, see "Image stabilization
control ".
• Laser light intensity correction control
• Color registration correction control (main scan/sub-scan)
• Gamma correction
