2214 Developer Initialization
2214 1
Initializes the TD sensor toner supply target voltage and the TD sensor gain value. Execute
this SP replacing the developer or the TD sensor.
2221 ID Sensor Error Analysis (* "ID Sensor Error Analysis (SP2-221)")
2221 1 Vsg Displays the Vsg value.
2221 2 Vsp Displays the Vsp value.
2221 3 PWM Displays the PWM value.
2221 4 Vsdp Displays the Vsdp value.
2221 5 Vt Displays the Vt value.
2221 6 Vts Displays the Vts value.
2301* Transfer Current Adjustment (*"Image Transfer Current").
2301 1
Normal paper
[–2 = –4 μA / –1 = –2 μA / 0 = 0 μA / 1 = 2 μA / 2
= +4 μA]
Adjusts the current applied to the transfer roller when feeding from a paper tray. Use a
high setting if the user normally feeds relatively thick paper (within spec) from a paper tray
2301 2
Thick/Special paper
[–2 = –4 μA / –1 = –2 μA / 0 = 0 μA / 1 = 2 μA / 2
= +4 μA]
Adjusts the current applied to the transfer roller when feeding from the by-pass tray. Use
a high setting (a) if the user normally feeds relatively thick paper from the by-pass tray, or
(b) if waste toner is re-attracted from the drum (which can occur when using transparencies).
2301 3
Duplex
[–2 = –4 μA / –1 = –2 μ/ 0 = 0 μA / 1 = 2 μA / 2 =
+4 μA]
Adjusts the current applied to the transfer roller when carrying out a duplex job. Use this
SP if there is poor image transfer on the rear side of duplex copies.
2301 4
Cleaning [–10 to 1 / –1 / 1 μA/step]
Adjusts the current applied to the transfer roller for roller cleaning. Increase the current if
toner remains on the roller after cleaning. (Remaining toner may cause dirty background
on the rear side.)
