如何选择针式打印机色带?

点击次数:  更新时间:2010-06-09 21:12:08  【打印此页】  【关闭

好色带=出色效果=长寿命
   其实说到底决定针式打印机效果和使用寿命的最重要因素是打印色带的质量,它往往容易被人忽视,我们可以看到很多皱皱巴巴的色带已经快没色了,用户还在用却美名其曰:节省成本,可是他不清楚这样非常容易造成断针,换个打印头要多少钱啊?和二十多元的色带相比,无疑是捡了芝麻丢了西瓜!优质色带一般能打印300万字符以上,而劣质色带往往打印10万-20万字符左右就无法继续使用,二者相差达数十倍,因此学会正确鉴别色带的质量并进行选择,是每个针式打印机用户必须掌握的技能。

    鉴别针式打印机色带质量的高低主要从带基、接头焊缝、油墨和长度等四个方面入手。
  1、 色带带基是以尼龙丝为原料织成,色带质量决定着色带的使用寿命和油墨的附着渗透能力。应选择使用高密度尼龙66织成、经纬密度在每厘米130线以上、纤维状态为无缠绕、不起毛、不变形的高密度带基。挑选色带时,可将色带对着灯光观看,不能透过光线的一般来说是高密度带基,质量较好。如能够透过光线,则表明其带基密度未达到标准要求,由这种低密度尼龙织成的色带,其打印质量自然要大大折扣,而且这种色带特别容易挂针。
  

  2、 对色带接头焊缝的基本要求是:焊接角度应大于30度、接缝处连接平滑、没有明显的接痕或凸出,能够保持带基的原纤维特性并正常均匀地吸收油墨。优质色带的焊缝都是使用超声波焊接机焊接而成,能够有效保证接头质量。而使用简单的热熔或热压方法焊接的焊缝均不同程度地破坏了带基的纤维特性,导致焊缝处呈现明显凸出的双层接头,且接口不平滑,这种色带常会使打印针不能及时退回,从而严重磨损、挂伤甚至折断打印针。因此选购色带时应仔细观察其接头焊缝情况。
  

   3、色带油墨应适中,过多或过少都会影响打印效果。优质色带的油墨都经过了脱脂处理,附着力强,能渗透到带基纤维内部,看起来比较干爽,用手触摸时,手指上不会留下明显的油墨痕迹。这种油墨的印墨过程非常均匀,前后打印效果没有明显的差别。而一些劣质油墨,用手去触摸时是油腻腻的,手指满是油墨痕迹,看似油墨充足,但在打印时会出现色重现象(颜色过浓),即用手触摸打印纸就会模糊一片,隔一段时间就明显变淡,使用寿命比较短。劣质油墨不但打印效果很差,而且它可沿着打印针导孔进入打印头缝间并固化,堵塞打印头,导致打印机无法正常打印,严重时可造成打印头出针阻力增大而折断打印针、打印针平行槽被压坏、打印头驱动芯片或色带电机被烧坏等故障。
  

    色带的长度也是分辨色带优劣的总要标志:不同类型的打印机用不同的色带。例如:NEC P1200/1300/3300/200 EPSONLQ100/150/DLQ1000/LX100色带长度为16米,LQ1500/2500色带的长度为10米。劣质的色带往往在长度上 不符合标准。
  

     低廉的售价是劣质色带赖以生存的条件,并使得它有一定的市场,吸引了不少的消费者。但是由于其使用寿命很短,需要频繁更换,导致打印机始终处于不良运行状态而损坏。因此广大用户千万不可只看色带价格而忽视对其质量进行鉴别,否则会造成很大的经济损失。
