17.4 General Maintenance

General maintenance for the Westrex Serial Printer consists of the following
activities:
♦ Perform a printer self-test:
1. Open the cabinet door, and switch OFF the machine.
2. While depressing the Feed switch (shown in Fig 17-2), switch the
machine power ON.
3. After a few seconds, the self-test will start printing. Once printing, the
feed switch can be released.
4. Check the print quality of the self-test. If the printout is not clear, replace
the ribbon cassette.
♦ Check that all connectors are secure.
♦ Make sure that receipts are falling correctly into the coin tray.
♦ Check that the journal is being rolled properly onto the journal spool.
