5-2 Fusing unit errors

Temperature control error
No.
1. Repower the printer. If problem is not resolved,
go to step 2.
2. Improve the connection between the fusing unit
and its connectors.
3. Does heater lamp 1 (H1) come on when the
power supply is turned on?
4. Does heater lamp 1 (H2) come on when the
power supply is turned on?
Others
An error is detected in the fusing motor when one of the following items is detected:
1. Service Call 1B FUS UPPER THERM: After the warm up has started, a thermistor error is detected when the tem-
perature of the heater roller does not rise to the specified temperature within 22 to 40 seconds.
2. Service Call 1E FUS LOW HIGTMP: After the warm up has started, a high temperature error for the pressure
roller is detected if the temperature of the pressure roller exceeds 80° C/176° F within 90 seconds.
3. Service Call 1A FUS UPP HIG TMP: After the warm up has started, a heat-rise temperature error is detected when
the temperature of the heater roller exceeds 170° C/338° F within 140 seconds after it has reached 80° C/176° F.
4. Service Call 1F FUS LOW THERM: After the warm up has started, a pressure roller heat error is detected if the
temperature of the pressure roller does not reach 130° C/266° F within 70 seconds or does not exceed 150° C/302° F
within 140 seconds, after the temperature of the heat roller has reached 170° C/338° F or more.
5. Service Call 1D FUS LOW LOWTMP or Service Call 19 FUS UPP LOWTMP: If during printing a low fusing
temperature error is detected at the heater roller, or the pressure roller during standby falls below 70° C/158° F.
6. Service Call 18 FUS UPP WARMUP or Service Call 1C FUS LOW WARMUP: A high fusing temperature error
is detected if the temperature of the heater roller during temperature control rises above 210° C/410°F, and if the
temperature of the pressure roller rises above 195° C/383° F.
7. Service Call 18 FUS UPP WARMUP: Heater roller does not heat up to 160° C/338° F within 70 seconds
8. The hardware high breaker temperature is 220° C/428° F for the heater roller and 205° C/401° F for the pressure
roller. The thermostats are 210° C/410° F for the heater roller and 150° C/302° F for the pressure roller.
