3.7 Print Gap Control The print gap control is a rotary adjustment that adjusts the distance between the paper and the print heads (see Figure 3–10). It has a scale from less than one to more than six, and should be nominally set to the same point on the scale as the PAPER THICKNESS scale. Adjust this and the paper tension lever to obtain the best print quality.
Chapter 4 SETTING COMMUNICATIONS AND PRINT PARAMETERS 4.1 Introduction This chapter defines the user settable parameters of the LG31 printer. There are two ways for setting parameters in the LG31. Some of the parameters can be set by either method.
There are two parameters and two sets of adjustments that can be made in the function mode. In the function mode, you can perform operations in one of the categories, and then you must exit to off-line. You can then begin the process again to perform operations in another category. The process for listing the parameters in these categories and making changes to them is given in the following sections. 4.

Chapter 5 PRINTER DIAGNOSTICS 5.1 Introduction This chapter describes the LG31 self-tests and the alignment tests. 5.2 Self-Tests The printer automatically verifies its operational integrity by performing the power-up self-tests on power-up. Thereafter, it continually performs the operational self-tests. In addition to these tests, the operator can invoke the printing self-tests. 5.2.
5.2.2 Printing Self-Test The LG31 printer can execute a printing self-test from either the outer or inner control panel. This test prints the 94 printable characters of the ASCII character set in the data processing font, at 10 CPI, and 6 LPI. The test is printed in a swirl pattern over the maximum printable width (see Figure 5–1). Faults are displayed at the control panel. Table 5-1 contains the procedure for an off-line print test. Table 5-2 lists the diagnostic fault codes.

6.3 Installing/Replacing Ribbon Cartridge To install the ribbon cartridge, carry out the following steps: 1. Open printer top access door with the cover interlock switch (located on the top left of the printer). 2. Raise cover interlock switch to its highest position. 3. Clear the [ c o ] (cover open) error indicator, by pressing the text CLR push button. NOTE In replacing the ribbon cartridge (paper thickness remains unchanged), note the paper gap adjuster setting for use in step 7. 4.
5. If replacing the ribbon cartridge unsnap ribbon cartridge holddown at left side of ribbon cartridge (see Figure 6-5). NOTE The LG31 printer has a ribbon weld sensor that detects the point where the two ends of the ribbon are welded together. Printing is temporarily suspended for a few seconds until the ribbon weld passes a certain point for printing to resume. If display [ S U S] persists for more than one minute, it may be caused by a damaged ribbon or defective ribbon weld detector. 6.
8. Tilt ribbon cartridge downward to the left and install left side first (left edge of cartridge will guide ribbon between the ribbon guide and shield as shown in Figures 6-5 and 6-6). Then lower right side onto ribbon motor drive shaft. Turn knurled knob a few times to verify that ribbon is running freely and to remove any remaining slack. 9. Snap ribbon cartridge holddown in place over left side of ribbon cartridge. 10.
