Long self test
To see the printer's variety of type styles, you can run the long version
of the printer's self test.
I.
Check that paper is in position for printing.
2. With power off, press the Paper Feed switch on the control panel and
hold it down.
3. Still holding the Paper Feed switch down, tum the printer's power ON.
The printer will automatically start printing a test pattern of its full
character set in various type styles. Watch the lights on the control panel;
they indicate which type style is printing.
This test repeats indefinitely in a cycle of 125 lines. To stop the test,
switch power off.
Interface test
After confirming that the printer works by itself, it is time to test the
interface with the computer. Power up both the printer and computer, load
paper, then try running the following BASIC program:
10 OPEN4.4
20 FOR 1=1 TO 10
30
PRINT=II:4. "THE INTERFACE WORKS"

This program prints a line of text 10 times. The OPEN, PRINT#, and
CLOSE commands will be explained in Chapter 3. DIP switch 3 must be
ON (the factory setting) for this program to work.
ADJUSTING THE PRINTING GAP
The distance between the print head and the platen can be adjusted to
accommodate different paper thicknesses. To make this adjustment, remove
the top cover. The adjustment lever is located near the left end of the paper
bail. Pulling the adjustment lever towards you widens the gap; pushing it
away from you narrows the gap.
There are foui positions; you can feel the lever clicking into each position.
The first position (narrowest gap) is the one most commonly used for single
sheets of paper. Try different positions until you get the best printing results.
