Troubleshooting and maintenance
This section helps you identify printer conditions and problems that you can often correct. When you first recognize a problem, determine whether it is located within the printer, the software application, or an option. For additional assistance and answers to your questions, contact your service representative.
When diagnosing a problem, see “Checklist for typical problems” on pag e112.

Checklist for typical problems
To solve most basic problems, begin by following these steps:
1
Is power getting to the printer?
Make sure:
•
The power cord is both plugged into a properly grounded outlet and into the printer.
•
The other items plugged into the same power source are operating.
•
The power source cannot be turned Off by a wall switch.
112
2
Is print too light?
The ribbon density control knob has been preset to 1. (The knob is located on the ribbon cartridge.)
When print becomes light, turn the knob from
1 to 2 to increase darkness of print.
Ribbon density control knob
Ribbon advance knob
3
Is paper jamming the printer?
See “Clearing paper jams” on pag e126 for
information on clearing paper jams.
4
Are forms catching on items such as a forms carton or a printer stand?
Adjust the forms container so paper feeds freely from container to printer.
5
Is a part damaged?
Call for service.
113
6
Are options causing the problem?
a
Run the Printer Test. For more information,
see “Testing the printer” on pag e116.
b
If the Printer Test fails with no options installed, call service.
c
If the Printer Test fails with an option installed, try removing the option.
7
Is the Font or Pitch selected from the operator panel not printing or is it changing?
Set Font Lock or Pitch Lock On to keep your software application from overriding the font and pitch settings. For more information, see
“Selecting or locking a font” on page 31.
If you need to use a nonresident font, change the font within your software application.
Note: If you are using Windows programs, most
fonts are bitmapped (graphics) and override the printer Font or Pitch Lock.
Select a resident font to override from the operator panel.
8
Is the problem outside the printer?
a
Turn the printer Off.
b
Disconnect the printer cable from the back of the printer.
c
Run the Printer Test. For more information,
see “Testing the printer” on pag e116.
If the Printer Test runs, then the problem is in the printer cable or your computer.
d
Run the test procedures for your computer.
For more information, refer to your computer’s operator manual.
9
If a software application does not run correctly on the printer, does a different software application run correctly?
114
10 Are you experiencing unexpected printing
results?
Make sure:
•
You selected the appropriate printer driver for your software application. For more
information, see “Setting up your Windows and DOS application software” on pag e17.
•
You selected the appropriate emulation mode for your printer. For more
information, see “Using IBM emulation mode” on page 18.
11 Do the buttons on the operator panel not work
except for Start/Stop, LineFeed, FormFeed,
Tear Off and Load/Unload?
The operator panel is locked. For more
information, see “Locking/unlocking the operator panel” on pag e30.
115
Testing the printer
Each time you turn the power switch On, the printer performs an internal check, or Power-On Self Test.
