5. Controlling the Power Supplied to the Fixing Heater between Sheets
When the copying speed is controlled to 6 cpm to prevent overheating of the copyboard, the
temperature of the fixing lower roller tends to increase because of the increased sheet-to-sheet
distance. To prevent possible problems, power to the fixing heater is stopped between sheets when
the copying speed is controlled to 6 cpm.
