打印模式:BJ模式和LQ模式.SW11=OFF时,为bj模式,sw11=on时,为lq模式.
把打印机设置成lq模式时,在硬件上设置好后,在软件上把打印选择epson打印机,即wps打印时,”打印机类型”中选择epson nec”系列.如”ar-3240”即可.

bj-10es/sx 检查松纸纸杆是否按下(若未被按下,则不能正确进纸);同时按住lf/ff和power键,当蜂鸣器叫后,松开power键,当蜂鸣器再次鸣叫后,松开lf/ff和power键,power灯error灯亮;将一张纸插进打印机内;按下lf/ff键,进纸到预定位置;按下online键,开始打印自检样张。 
1、关机,按住fwdadj和revadj的同时按下power键;
2、当蜂鸣叫后,松开power键蜂鸣器再叫后,松开其余两键,开始清洗。 
BJ-230H   开机后,按灭ONLINE灯。用“>;”选择“1CLEANING TEST”再按一次“v”出现“CLEANING”,开始清洗。
