This kind of green laser pointer has been attracting

This kind of green laser pointer has been attracting more and more attention of more and more customer.
Should be noted that the detector false positives out of paper, not necessarily caused by the error of the detector itself. The use of color or the existing character of the printing paper, is able to absorb more light, the same phototube conduction, not online. There are three ways you can choose: Modify the EDS set out of paper to detect invalid (setting method, see the random operation manual). The printer will unconditionally online printing, regardless of whether the paper. However, doing so has one drawback is that when the user exhausted paper, the printer will continue glue stick meaningless print. Therefore, it is generally not recommended to use this feature. The energy of the laser beam emitted by green laser pointer can be concentrated within a very narrow range.
Therefore, more and more customers will be attracted by green laser pointer
Think of a way from the hardware, the signal of the examination paper is removed from the phototransistor resistor. Order to meet the signal is weak, the resistor replacement, replace them with larger resistor. The +5 V supply on its partial pressure, and improve the signal value. This with phototube conduction, a larger current through the resistor, the higher signal value is the same. Another option is to make software changes for the new STAR printer users. Such as the AR6400 printer, you can modify the DOS QBASIC language EEPROM, and to enable the printer to adapt to the weaker signal. Platen lever position detector. The detector is a mechanical switch. The bigger the power of green laser pointer is, the farther the laser pointer can reach.
When the switch is on, press the paper lever down to issue a +5 V signal; pressure the paper lever rises when the switch is closed, issue the OV signal. Platen lift the lever in the beginning of the feed, the feed end of fall, if the user set in the EDS 1/6 inch sheet of paper empty, press the paper lever stranded in a period of time, and then fall in the printing process. Platen lever is not in place, the printer will report an error crash. Here are a failure instance. Fault phenomenon: a AR3200 printer, press the paper feed lever lift, rack the left side of the noise, and then crash. AR3200 and AR3200 + printer does not require a dedicated relay, but through a complex series of gears operating pressure paper lever action. The operation of green laser pointer is very easy.
