SERVICE PROGRAM MODE
Function
Adjusts the fusing temperature for
paper fed from a paper tray.
Adjusts the fusing temperature for
paper fed from the by-pass feed unit.
Displays the fusing temperature.
Checks the fusing nip band
Refer to "Nip Band Width Adjustment"
for more details.
Adjusts the paper switch back timing
Use this SP mode when paper often
jams at the inverter gate in the duplex
unit.
Adjusts the voltage applied to the
charge roller during copying.
After replacing the drum or charge
roller, change this value to the default.
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
SP2-001-1.
Do not adjust.
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).
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).
Adjusts the lower limit value for charge
roller voltage correction.
Adjusts the upper limit value for charge
roller voltage correction.
