The printer may not be securely connected to the computer. Check both ends of the cable between the printer and the computer.

Your software’s font, page layout, printer port, or other printer settings may not be selected properly. Make sure your software is correctly set up for your printer and that you specify continuous-feed paper as the type of form.

If the printing is too high or low on the page, adjust it by following the instructions in the sections in Chapter 2 on adjusting the top of form position and adjusting the printing position.

Your application program may be changing the SelecType or DIP switch settings. Use the program’s setup procedure to remove the interfering codes, or use the printer control codes for your application program instead of SelecType or DIP switches. See your software manual for more information on removing interfering codes. Also, for more information on sending printer commands, see the section on sending commands to the printer in Chapter 4.

Make sure that the DIP switches are set correctly for use with the built-in parallel or serial interface. See the section on DIP switch settings for interface type, parity, and baud rate in Chapter 3. You can also check the DIP switch settings by running the self test. (See Chapter 1.)

If you are using an optional interface board, make sure that DIP switches 2-5 and 2-6 are set for parallel, regardless of whether the optional board is parallel or serial. See the section on DIP switch settings for interface type in Chapter 3. Also, make sure that the DIP switches on the interface board are set according to the instructions in the interface board manual.
