Leading edge
2101 1
Adjusts the leading edge erase margin.
Trailing
2101 2
Adjusts the trailing edge erase margin. The rear trailing edge is this value plus
1.2 mm.
Left side
2101 3
Adjusts the left edge erase margin. The rear left edge is this value plus 0.3
mm.
Right side
2101 4
Adjusts the right edge erase margin. The rear right edge is this value plus 0.3
mm.
Development Bias Adjustment
2201*
Printing
2201 1 Adjusts the voltage applied to the development roller when printing. This can
be adjusted as a temporary measure if faint copies are being produced due to
an aging drum.
ID sensor pattern
2201 2 Adjusts the voltage applied to the development roller when generating the ID
sensor pattern. The actual voltage applied is this setting plus the value of SP
2201 1. The setting affects ID sensor pattern density, which in turn affects the
toner supply.
Outputs after Near End
2213*
[0 = 50 pages / 1 = 20 pages]
Sets the number of copy/print pages that can be made after toner near-end
2213 1
has been detected. Reduce the number of pages if the user normally makes
copies with a high image ratio.
Developer Initialization
2214
Initializes both the TD sensor toner supply target voltage and the TD sensor
2214 1
gain value. Carry this out after replacing the developer or the TD sensor.
TD Sensor Output Value Display
2220
Displays:
1. Vt: the current TD sensor output value and
2. Vref: the target TD output value Vts (SP 2926) + correction for
2220 1
ID sensor output.
The TD sensor output value changes every copy. If 1 > 2, toner is supplied to
the development unit.
