*1 | High Temperature CPM Down |
If the fusing temperature exceeds the high temperature limit prescribed for these sensors, CPM down control changes the feed timing to create a wider interval between the sheets of paper feeding through the fusing unit. | |
*2 | Hot Roller Idling |
In Ready mode the hot roller does not rotate constantly to maintain a correct even temperature on the hot roller, but if the machine remains in Ready mode for a long period, the hot roller may cool. If Fusing Temperature Thermistor (Hot Roller Center), which monitors the center of the hot roller, detects that temperature has dropped below its prescribed limit, this triggers hot roller idling for the prescribed interval to bring the temperature up to operational level. | |
*3 | Idling to Prevent Overheating |
In the Ready mode, or when the machine returns from low power mode, if these sensors detect temperature above 215oC (default), the machine will not drive the hot roller and belt until temperature has fallen below the prescribed limit. |
