Service Manual for OF5800 Chapter 2 Machine Operations Page: 32 The Thermistor (TH1 detects the surface temperature of the Upper Fusing Roller and inputs that analog voltage into IC1-77. Corresponding to this data, the Heater Lamp ON/OFF signal is output from IC1-54, causing the Heater Lamp (H1) to turn ON or OFF to control the fusing temperature. If the Heater Lamp is still on after the Thermistor detects a high temperature malfunction (the surface temperature of the Upper Fusing Roller exceeds 200 °C), the signal from IC1-75 changes from H to L to turn OFF the Heater Lamp. 1. Warm Up - After the initialization of the printer, warm up of the printer starts and the Heater Lamp turns ON until the temperature of the Upper Fusing Roller reaches approx. 172 °C. 2. Standby - In standby mode, the temperature of the Upper Fusing Roller is maintained at 156 °C. After 3 minutes, the printer turns to power save mode. The fuser is kept at low temperature. 3. Print Cycle - When the printer obtains the printing command from its controller, the Upper Fusing Roller is maintained at 172 °C. 4. Standby at Low - The Upper Fusing Roller is maintained at temperature 112 °C. Copyright 1997, Okidata, Division of OKI America, Inc. All rights reserved.
