The fixing system is constructed of the following components:

Fixing upper roller           Heat roller (50-mm dia.)

Fixing lower roller            Pressure roller (38-mm dia.)




Fixing motor                        M19          24VDC




Fixing assembly inlet          SL1  24VDC


guide drive solenoid


Main heater                     H1       120/230-V model: 600 W
                                      100-V model: 700 W





Sub heater                         H2      120/230-V model: 600 W
                                                     100-model: 470 W



Main thermistor                  TH1  Used for temperature control, error detection

Sub thermistor                   TH2   Used for error detection

Thermal switch                    TP1   Operates at 240 ±10°C


Cleaning web                    • Driven by web drive solenoid (SL2)
                                        • For large-size paper (B4 or larger), turns on twice
                                         for the 1st sheet, and then once for the 2nd and 3rd
                                         sheets; repeats the sequence thereafter
                                        • For small-size paper (smaller than B4), turns   on
                                          once for the 1st and 2nd sheets, and remains off for
                                          the 3rd sheet; repeats the sequence thereafter

Upper separation claw       Moves in reciprocating motions (about 3 mm)
                                            Moves up/down (about 1.8 mm)
