2.5 Powering and Testing the LG31 Printer
LG31 printer testing includes a self-test and a print test. The self-test
is performed:
• Every time the printer power is switched on.
• After each print test.
• During normal operation.
Before turning the power on, load the printer with paper (see Chapter 6,
Section 6.2). To turn the power on and run the print test, perform the
following steps.
1. Turn the LG31 printer on by pressing the top section of the power
switch (see Figure 2–9). The printer performs a series of self-tests
(see Chapter 5, Section 5.2) and when completed, displays [ O F L].
2. Press the (3) ON LINE key if [ O n L] is displayed.
3. Press the (0) TEST CLR key until the LG31 begins to print. The
LG31 will print the test pattern until you press the (0) TEST CLR
key again.
4. Compare the printout from this test with the sample printout sup-
plied with the printer.
5. If the printout is comparable, continue by running a configuration
printout (see Section 4.3.1).
6. If the quality of the printout is unsatisfactory, perform the printer
adjustments in chapter 5 of the Technical Manual.
The configuration menu contains the state of the printer as shipped. You
should print a copy of this menu and retain it for future reference. To
print a copy of the configuration menu, perform the following steps.
NOTE
The factory settings for the printer parameters are contained in
Chapter 7, Section 7.3 (Table 7–3). The setting of parameters at
power-up and at reset are also listed in Chapter 7 (Table 7–4).
1. Make sure the LG31 is in the off-line mode ([OFL]isdisplayed).
Press the (3) ON LINE key if [ O n L] is displayed.
