This control is to prevent an overheating at both ends of the fixing sleeve by keeping the required speed for paper feeding and, in addition, extending the pickup
interval.
At continuous printing with the paper width narrower than A4 size (210 mm), the end of fixing sleeve may overheat.
If no paper is detected by the paper displacement sensor (SR714) on the registration roller at paper feed and, in addition, a detected temperature by the fixing sub
thermistor (TH2) exceeds the specified temperature, it is considered that either universal size paper or narrower width paper than A4 size is fed.
In this case, DC controller performs the throughput down control step-by-step according to the detected temperature by the fixing sub thermistor.
When the detected temperature is 250 deg C or higher, the controller extends the pickup interval by keeping the paper feed speed to lower the throughput. The sheet
interval gets longer, the fixing sleeve temperature becomes lower.
Firstly, 1st additional interval is added to the default pickup interval followed by paper feed.
If after 1st additional interval, the sub-thermistor again detects temperature of 250 deg C or higher and there is no change in the paper interval after five sheets, 2nd
additional interval is added. The 3rd and 4th intervals are added similarly.
T-10-1
When the fixing sub thermistor detects the temperature below 90 deg C for 2.5 sec or more after the throughput down control, throughput down control is canceled.
