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 overriding the DIP-switch settings. See your software manual for more information on selecting the desired settings or for removing interfering codes. For more information on sending printer commands, see Appendix B.

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 serial bit rate in Chapter 3.

If you are using an optional interface card, make sure that DIP switches on the printer are set for parallel, regardless of whether the optional card is parallel or serial. See the section on DIP-switch settings for interface type in Chapter 3.

Paper does not feed properly

The paper may not be mounted on the sprockets correctly. Make sure the sprocket holes of the paper fit correctly over the sprockets.

Make sure the sprockets are positioned to match the width of your paper and that they are locked in place with their covers closed.

Check the paper on the tractor’s sprockets to make sure it is not ripped, jammed, or skewed. If something is wrong with the paper, tear off the paper below the tractor and press the LF/FF button to eject the remaining paper. Then load fresh paper, making sure the first sheet has a clean, straight edge.
