Outline of Operation fixing system canon image runner copiers part 1

The fixing system has the following major functions:

Fixing method                       Heat roller

Fixing heater
100-Vmodel                     Main heater: controlling temperature mainly during printing
                                         Sub heater: controlling temperature during standby
120/230-V model              Main heater/Sub heater: controlling temperature during printing

Control temperature           200°C (in STANBY)



Temperature detection        [1] Main thermistor (temperature control, error detection)
                                          [2] Sub thermistor (error detection)
                                          [3] Thermal switch (error detection)





Fixing temperature control   [1] Power-on sequence
                                           [2] Model-specific sequence
                                           [3] Ambient temperature sequence






Cleaning method                Web roller (driven by solenoid and one-way clutch)




Error detection                     [1] By thermistor (temperature error)
                                            [2] By thermal switch (overheating)

Other                                  [1] Control of fixing assembly inlet guide drive (about 1 mm  up/down)
                                              • High if original is B5R or longer
                                               • Low if original is shorter than B5R                                                
                                            [2] Control of reciprocating movement of thermistor (about
                                                    12 mm)
                                            [3] Control of reciprocating movement of upper separation
                                                  claw (about 3 mm)
