3. 5. 12 DC131 744-xxx Fuser NVM List
1. 744-001
[NVM Name]: STS-1 Control Temperature in Low-Power Mode
[PSW Display]: STS-1 CONT TEMP in Low PWR Mode
[Initial Value]: 80
[Setup Range]: 0~160 (1 Count: 1 Degrees Celsius)
[Description]:
Main-Lamp temperature control in Low-Power Mode.
Setting the default as 0 Degrees Celsius is same as Fuser-Off. It is necessary for
high temperature for recovery Time Claim.
2. 744-002
[NVM Name]: STS-2 Control Temperature in Low-Power Mode
[PSW Display]: STS-2 CONT TEMP in Low PWR Mode
[Initial Value]: 80
[Setup Range]: 0~160 (1 Count: 1 Degrees Celsius)
[Description]:
Sub-Lamp temperature control in Low-Power Mode.
Setting the default as 0 Degrees Celsius is same as Fuser-Off. It is necessary for
high temperature for recovery Time Claim.
3. 744-003
[NVM Name]: UM status by High Temperature Error Detection
[PSW Display]: UM status by High Temperature Error Detection
[Initial Value]: 0
[Setup Range]: 0~2
[Description]:
0 (Normal) or 1 (STS-1 High Temperature Error Detection) or 2 (STS-2 High
Temperature Error Detection).
UM Status occurs when either STS-1 or STS-2 High Temperature Error Detection
is detected.
Once this occurs, UM cannot be canceled unless this NVM value is changed to 0
by entering the Diag Mode in the Interlock-Open status of the M/C-Front Cover.
4. 744-004
[NVM Name]: STS-2 High Temperature Not-Ready Temperature
[PSW Display]: STS-2 High-TEMP-Not-Ready TEMP
[Initial Value]: 220
[Setup Range]: 150~250 (1 Count: 1 Degrees Celsius)
[Description]:
Once the STS-2 reaches High Temperature Not-Ready Temperature, the Fuser is
moved to sagging status.
This is because when continuous Run is performed for A5SEF and below,
Temperature Distribution Control would fail.
5. 744-005
[NVM Name]: STS-1 Ready Temperature
[PSW Display]: STS-1 Ready Temperature
[Initial Value]: 150
[Setup Range]: 100~150 (1 Count: 1 Degrees Celsius)
[Description]: For an appropriate distribution of [Ready to copy] Temperature.
6. 744-006
[NVM Name]: STS-2 Ready Temperature
[PSW Display]: STS-2 Ready Temperature
[Initial Value]: 127
[Setup Range]: 100~150 (1 Count: 1 Degrees Celsius)
[Description]: For an appropriate distribution of [Ready to copy] Temperature.
7. 744-007
[NVM Name]: STS-1 Stand-by Temperature
[PSW Display]: STS-1 Stand-by Temperature
[Initial Value]: 160
[Setup Range]: 100~200 (1 Count: 1 Degrees Celsius)
[Description]: For an appropriate distribution of Standby Temperature.
8. 744-008
[NVM Name]: STS-2 Stand-by Temperature
[PSW Display]: STS-2 Stand-by Temperature
[Initial Value]: 160
[Setup Range]: 100~200 (1 Count: 1 Degrees Celsius)
[Description]: For an appropriate distribution of Standby Temperature.
9. 744-051
[NVM Name]: Environment Temperature Correction deg
[PSW Display]: Environment Temperature Correction deg.
[Initial Value]: 3
[Setup Range]: 0~5
[Description]:
Environment dependent correction coefficient for level of fusing.
Temperature AD value shift amount when the environment temperature varies 1
Degrees Celsius from 20 Degrees Celsius.
