防止卡纸的激光打印装置

Laser printing device preventing paper jam

Abstract

本实用新型涉及一种防止卡纸的激光打印装置,包括感光鼓,墨粉盒,转移单元,激光组件,定着器组件,所述激光组件发出激光光电信号至感光鼓,在感光鼓上产生带有不同电荷的部位,墨粉盒上的碳粉吸附在感光鼓上的带有不同电荷的部位上,感光鼓上的碳粉随转移单元转移至打印介质上,打印介质被传送至定着器组件加热定着,所述定着器组件的外侧设有微动开关,所述微动开关与打印装置的控制电路相连接,所述微动开关外接金属弹簧片,所述金属弹簧片的自由端位于打印介质的上方和\或下方并与打印介质的表面存在间隙,所述微动开关通过金属弹簧片按压来实现对打印装置的控制电路的断开。本实用新型有效防止了纸张堵塞的现象,使用效果好。
The utility model relates to a laser printing device preventing paper jam, which comprises a photosensitive drum, an ink powder box, a transferring unit, a laser assembly and a fixed device assembly, wherein the laser assembly transmits a laser photoelectric signal to the photosensitive drum, parts with different electric charges are generated on the photosensitive drum, carbon powder on the ink powder box is adsorbed onto the parts with different electric charges on the photosensitive drum, the carbon powder on the photosensitive drum is transferred onto a printing medium along with the transferring unit, the printing medium is transmitted to the fixed device assembly to be heated and fixed, the outer side of the fixed device assembly is provided with a micro switch, the micro switch is connected with a control circuit of the printing device, the micro switch is externally connected with a metal spring leaf, a free end of the metal spring leaf is arranged above and/or below the printing medium, a clearance is formed between the micro switch and the surface of the printing medium, and the micro switch disconnects the control circuit of the printing device by pressing the metal spring leaf. The laser printing device can effectively prevent the jam phenomenon of the paper and has a good application effect.
