  • Page 43: Stx-Etx Mode

    9-3. STX-ETX Mode The start of the STX-ETX mode should occur with a totally empty print buffer. This can be achieved by sending an ENQ code to the printer and checking the status until the status code indicates an empty buffer. At that point, the STX code is sent by the host computer followed by a data block.

    13. FERRITE CORE INSTALLATION ( EU ONLY ) If a peripheral unit drive circuit is to be used, attach a ferrite core using the following instructions. A ferrite core noise filter for the peripheral unit cable comes packed with the printer for distribution throughout the European Union.
  • Page 55 Clamp the ferrite core onto the peripheral unit cable, looping the cable as shown in Figure 13-2. • Take care to avoid damaging the cable when installing the ferrite core. • The ferrite core should be anchored firmly in place with the fastener that comes with it, as shown in Figures 13-3.
