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)
