C3926 (bizhub C554e/C454e)
Contents
| Trouble type | Fusing sensor wire breaks detection (Middle of the heating roller) |
| Trouble code | C3922 |
| Rank | A |
| Detection timing | • After a predetermined period of time after the warm-up stage is started, the heating roller thermistor/2 (TH2) voltage does not decrease by predetermined steps (temperature rise) within a predetermined time. • When a temperature detected by the heating roller thermister/1 (TH1) is compared with the temperature detected by the heating roller thermister/2 (TH2) to find out that the difference exceeded the predetermined temperature. |
| Trouble isolation | – |
| Relevant electrical parts | • Fusing unit • Heating roller thermistor/1 (TH1) • Heating roller thermistor/2 (TH2) • Printer control board (PRCB) |
