For new Lemur models with BR## logic boards and all Lemur-X and Lemur-Z 

Low Paper SQ Opto Indicator Kit for use with ticket stack  P/N S424084


Each kit comes with the following: 

  • Cable to connect opto to the printer
  • SQ opto. 
  • Mounting hardware 

The paper low SQ opto is to be mounted on the side of the ticket locator tray to the customer’s specified height. The distance from the SQ opto eye to the side of the ticket stock should be no greater than .125” (3.18mm) but may be less. Below shows one possible mounting configuration. The opening may be round or square but must be large enough to not short any of the components on the board to metal. The sensor is installed onto the roll holder arm in the following manner.

The black connector of the cable is plugged in to the SQ opto that is keyed. The other end is connected to the low paper connector on the printer.

Image above shows the connector on a Lemur-Z

In the Lemur-X and Lemur-Z a low paper condition is signaled when the printer returns a low paper status message (In Hex 0F, in decimal 15) to the host computer. The low paper condition is detected when the SQ opto no longer detecting the paper. Once the low paper status is returned it will not be returned again until the triggering condition has been reset. This is accomplished by loading stock so the opto eye is covered and cycling printer’s power.


The host computer can also solicit the current status of the printer by sending an FGL status request (<S1>) command. The printer will respond with a paper low status if the paper low state has been reached and the printer is online (paper out hasn’t been reached) otherwise is will return an X-ON status
