    • A color printer includes a plurality of platens arranged on paper feeding path to feed paper on which a plurality of printing areas are arranged in series, a plurality of print heads arranged on the feeding path to face the platens to print data on the same printing areas of the paper fed on the feeding path, a feeding roller for feeding, to the print heads, the paper along the feeding path, a front-edge sensing section disposed between the feeding roller and a print head nearest the feeding roller to detect that the paper has been positioned at a printing start position, and a plurality of head lift mechanisms for setting the print heads from the platens to a standby position apart from the platens before the paper is fed to the printing start position and to a contact position at which the print heads come in contact with the platens after the paper has been fed to the printing start position. Particularly, the color printer has an engine controller for sequentially driving the head lift mechanisms to set the print heads to the contact position when the front edge of the paper has reached positions slightly advanced over the print heads.
    • 一种彩色打印机包括布置在供纸路径上的多个压板,其中多个打印区域串联在该纸张上,多个打印头布置在馈送路径上以面对压板以在相同打印区域上打印数据 馈送辊,用于沿着馈送路径向打印头馈送纸张;前缘检测部分,设置在馈送辊和最靠近馈送辊的打印头之间,以便检测到, 纸已经被定位在打印开始位置,以及多个头部提升机构,用于在纸张被供给到打印开始位置之前将打印头从压盘设置到离开压板的备用位置,并且在该位置处 在纸张被送入打印开始位置之后,打印头与压板接触。 特别地,彩色打印机具有一个发动机控制器,用于在纸张的前边缘到达稍微超过打印头的位置的位置时顺序地驱动打印头提升机构以将打印头设置到接触位置。
