CONNECTION AND SELF-TEST

Install paper and ribbon before you connect the printer. Leave Printer
unplugged.

Plug Printer into appropriate AC outlet. Always use a 3-wire grounded out-
let.

Before connecting the Printer to the output device (e.g., TRS-80 Expansion
Interface), perform the Printer Self-Test, as follows:

1. Turn the Printer on. The power switch is located on the bottom rear of 
   the unit, to the next to the power cord.

NOTE: Do not perform the following Self-Test unless the Printer is loaded
with 15" paper. Otherwise characters will be printed on the Platen. This 
will wear out the print head.

2. Press the SELF-TEST button. The Printer should produce a full-line (132
   characters). Press the button again; the Printer will print out another
   line, and the carriage will return to its home position.

3. If the test characters are printed too close to the left margin (or per-
   haps are exceeding the margin), adjust the paper position by loosening
   both tractor mechanisms and sliding them to the correct position.

4. If characters are too light, release the Penetration LOCK (move it for-
   ward) and adjust Penetration Control toward the left. If characters are
   too dark, or are smudged

5. Turn off Printer and Computer, and you are ready to connect them.

6. Locate the twisted wire cable. Note that one end has a molded male plug.
   Connect this end to the jack on the back of the Printer. The plug is
   asymmetrical. If it won't go on one way, turn it over and try again.

7. Connect the other end of the cable to the TRS-80 Expansion Interface 
   Line Printer Card Edge. the cable must exit from the bottom of the 
   card-edge connector.

The Printer is now ready for operation.
