Sp2-Xxx: Drum - Ricoh B291 Service Manual

SP2-xxx: Drum

2001* Charge Roller Bias Adjustment
2001 1* Copying
Adjusts the voltage applied to the charge roller for copying.
2001 2* ID Sensor Pattern
Adjusts the voltage applied to the charge roller when making the VSDP ID sensor
pattern (for charge roller voltage correction). The actual charge roller voltage is
this value plus the value of SP2001 1.
Charge Roller Bias Correction
2005*
Charge Roller Voltage Correction 1
2005 1*
Adjusts the lower threshold value for the charge roller correction.
When the value of VSP/VSG is greater than this value, the charge roller voltage
increases by 30 V (e.g., from –500 to –530).
Charge Roller Voltage Correction 2
2005 2*
Adjusts the upper threshold value for the charge roller correction.
When the value of VSP/VSG is greater than this value, the charge roller voltage
decreases by 30 V (absolute value).
Charge Roller Voltage Adjustment 1
2005 3*
Adjusts the lower limit value for charge roller voltage correction.
Charge Roller Voltage Adjustment 2
2005 4*
Adjusts the upper limit value for charge roller voltage correction.
Charge Roller Voltage Step
2005 5*
Adjusts the correction voltage adjustment step size.
2101* Printing Erase Margin
Adjusts the leading edge (top), trailing edge (bottom), left, and right margins
2101 1* Leading Edge (Top)
2101 2* Trailing Edge (Bottom)
2101 3* Left Edge
2101 4* Right Edge
2101 5* Trailing Edge - Back side
2101 6* Back Side - Right
2101 7* Back Side - Left
2103* LD Power Adjustment
Adjusts the intensity of the laser for the copier, printer, and fax unit. The Copier
and Printer/Fax settings can be adjusted separately.
2103 1* LD1 (Copier)
2103 2* LD2 (Copier)
2103 3* LD1 (Printer, FAX)
2103 4* LD2 (Printer, FAX)
2103 5* LD1 Adjustment Start/End
2103 6* LD2 Adjustment Start/End
