2114* Binary Edge Processing Parameter
Allows setting a parameter for binary edge processing for the printer application
with FCI switched off. The value for this SP is enabled only when the printer is
initialized. In all other cases, the data registered in the software are enabled. This
SP allows adjustment of image quality if the desired effect cannot be achieved
with the default settings for edge processing. However, some settings could cause
defective images on white paper.
001 Leading Edge Pixel Level (1200 dpi)
002 Trailing Edge Pixel Level (1200 dpi)
003 Continuous Pixel Level (1200 dpi)
004 Independent Dot Pixel Level (1200 dpi)
005 Leading Edge Pixel Level (600 dpi)
006 Trailing Edge Pixel Level (600 dpi)
007 Continuous Pixel Level (600 dpi)
008 Independent Dot Pixel Level (600 dpi)
2115 Main Scan Beam Pitch Adjustment
A label attached to the LD unit service part lists the correct settings. Refer to these
settings when adjusting the beam pitch for LD0 to LD3.
001 Pitch Adjustment Between LD0 and LD1
002 Pitch Adjustment Between LD0 and LD2
003 Pitch Adjustment Between LD0 and LD3
2201* Development Bias Adjustment
001 Dev. Bias (Image)
Adjusts the development bias for copying when process control is off
[100~800/10 V]
Adjust as a temporary measure to compensate for an aging drum until the old
drum can be replaced.
002 ID Sensor Pattern
Adjusts the development bias used to create the ID sensor pattern. DFU
[100~800/10 V]
This SP and SP2201-004 must be changed together by the same amount.
003 OHP
Adjusts the development bias for copying with OHP sheets.
[100~800/10 V]
004 ID Sensor Pattern Dev. Potential
Adjusts the development potential to create the ID sensor pattern. DFU
[100~800/10 V]
This SP and SP2201-002 must be changed together by the same amount.
005 Vb Scale Voltage Setting
Sets the Vb target development bias voltage (Vb). DFU
[100~800/10 V]
