Abstract

PURPOSE:To cut down power consumption by detecting the operation state of a printer and stopping power supply for a heat source in a fixation mechanism in the case that the printer is on standby. CONSTITUTION:A power source control mechanism 3 is connected with a temperature detecting device 1d, a standby state detecting mechanism 4 for detecting the standby state of the printer based on the presence or absence of a printing data which is held and also based on whether the printing operation has been finished or not, and a power source 2. In the case that the standby state detecting mechanism 4 detects that the printing data is held by the printer or that the printing operation is being executed, the power source 2 is controlled by the output of the temperature detecting device 1d so that the temperature of a fixation roller 1a may become an optimum temperature for the fixation of toner. And also in the case that the standby state detecting mechanism 4 detects that the printer is in the state that all of the printing operations are finished without holding the data, that means, that the printer is on standby, the power source 2 is controlled by the power source control mechanism 3 so as to stop the power supply for the heat source 1c.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は電子写真式プリンタの定着装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a fixing device for an electrophotographic printer.

従来、この種の定着装置は印字中、待機中に関わらず、
定着ローラがトナー画像を記録材に定着するに必要な温
度を保つように常に熱源に電力を供給していた。Conventionally, this type of fixing device was used regardless of whether it was printing or on standby.
Electric power was constantly supplied to the heat source to maintain the temperature necessary for the fixing roller to fix the toner image on the recording material.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上述した従来の定着装置は待機中も熱源に電力を供給し
ているので、消費電力が大きいという欠点がある。The above-described conventional fixing device supplies power to the heat source even during standby, so it has the disadvantage of high power consumption.

c and a temperature sensor 1d. The heat source 1c is connected to a power source 2 to obtain electric power. The power supply control mechanism 3 includes a temperature sensor 1d, a standby state detection mechanism 4 that detects whether the printer is in a standby state based on the presence or absence of retained print data and whether the printing operation is completed, and a power supply 2. When the standby state detection mechanism 4 detects that the printer is holding print data or is in the process of printing, the temperature of the fixing roller 1a changes to that of the toner based on the output of the temperature sensor 1d. The power source 2 is controlled so that the temperature is suitable for fixing. Also, there is no retained data and all printing operations have been completed.

つまり待機状態にあることを待機状態検知機構４が検知
した場合、電源制御機構３は熱源１ｃへの電力供給を停
止するように電源２を制御する。That is, when the standby state detection mechanism 4 detects that the device is in the standby state, the power supply control mechanism 3 controls the power supply 2 to stop supplying power to the heat source 1c.
