Right side
[0.0 to 9.0 / 2.0 / 0.1 mm/step] ( Copy Adjustments
Printing/Scanning)
Specification: 2 +2.5/–1.5 mm
Adjusts the right edge erase margin. The rear right edge is this value plus 0.3 mm.
2201* Development Bias Adjustment
2201 1
Printing [–1500 to –200 / –650 / 1 V/step]
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.
2201 2
ID sensor pattern
[–2 = LL (220 V) / -1 = L (260 V) / 0 = N (300 V) / 1
= H (340 V) / 2 = HH (380 V)]
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.
2213* Outputs after Near End
2213 1
[0 = 50 pages / 1 = 20 pages]
Sets the number of copy/print pages that can be made after toner near-end has been
detected.
Reduce
the
number of pages if the user normally makes copies with a high image
ratio.
2214 Developer Initialization
2214 1
Initializes both the TD sensor toner supply target voltage and the TD sensor gain value.
Carry this out after replacing the developer or the TD sensor.
2220 TD Sensor Output Value Display
2220 1
Displays:
Vt: the current TD sensor output value and
Vref: the target TD output value Vts (SP 2926) + correction for ID sensor output.
The TD sensor output value changes every copy. If 1 > 2, toner is supplied to the
development unit.
