Abstract

PURPOSE:To eliminate the down time, by incorporating a battery in a copying machine and charging the battery during holding and supplying power from the battery to a fixing heater when the temperature of the fixing roller is lowered to a prescribed temperature or lower for the continuous copy. CONSTITUTION:A battery 11 and a fixing heater 12 are connected to a rectifier 10 for copy paper, and switches SW1-SW3 are provided. During holding, the switch SW1 is turned off, and the switch SW2 is turned on to charge the battery 11. When the continuous copy is started and the temperature of a fixing roller is lowered to a prescribed temperature or lower, switches SW1 and SW3 are turned on, and the switch SW2 is turned off, and power is supplied from the battery 11 to the fixing heater 12. Thus, since the temperature of the fixing roller is not lowered to a prescribed temperature or lower the down time is eliminated, and a high-capacity copying machine is obtained.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copy control method, and particularly to a copy control method in which the surface temperature of a fixing roller is gradually lowered within a fixable range as transfer material is continuously fixed. A battery is built-in, and the battery is charged during standby, and during continuous copying, when the temperature of the fuser heater drops below a certain temperature, power is supplied from the battery to the fuser heater, thereby reducing downtime. The aim is to eliminate this problem and provide a high-performance copying machine.

FIG. 1 is a configuration diagram of the main parts of a fixing device '2 that heats and fixes toner electrostatically adhered to a transfer material. (heat) roller, 3
4 is a pressure roller, and 4 is a transfer material.As is well known, the pressure roller 3 presses the transfer material 4 against the fixing roller 2, and the fixing roller 2 fuses the toner on the surface of the transfer material 4, and then removes the toner. The mapped image is fixed onto the transfer material 4. However, in the above-described fixing device, when an attempt is made to increase the copying speed, the amount of heat absorbed by the transfer material increases in proportion to the copying speed, and the fixing temperature decreases. Figure 2 shows the temperature characteristics of the fixing roller in that case. In the figure, curve A is the temperature characteristic of the fixing roller, and the period box is the standby period. As shown in the figure, when copying starts at a certain time, , the temperature of the fixing roller decreases according to the number of copies, and reaches the lower limit tx
If the temperature drops below rt, fixing will not be possible. To prevent this, you can increase the power applied to the heater, but
If this happens, the power consumption of the entire copying machine increases, making it impossible to use a general household power supply, and causing problems such as restrictions on the installation location of the copying machine. Therefore, in the past, a temperature detector was installed on the fuser roller, and when the temperature of the fuser roller fell below a specified value, copying was temporarily stopped and the system waited until the temperature of the fuser roller recovered to a predetermined temperature. However, during this waiting period (downtime), copies cannot be made, which is one of the factors that impairs the performance of the copying machine.

The present invention was made in view of the above-mentioned circumstances, and
In order to eliminate the downtime, the copying machine has a built-in battery, which is charged during standby.When continuous copying starts and the temperature of the fuser roller drops to a certain level, the fuser heater is also activated from the battery. This is to prevent the temperature of the fixing roller from dropping below a specified level.
