Self Test
To perform a self-test switch on the power to the printer at the same time as pressing the feed
switch and keep the feed switch depressed until the test starts. This will check the mechanism and
a large proportion of the software and hardware (except that dealing with the data interface) without
the need for connection to a host. An example of a typical self-test pattern is shown overpage. The
software issue is printed in double height, double width text, followed by the character set in normal
text. Below this are listed the current settings of the user selectable options. If the settings are
correct for your host, you are ready to connect the printer to your system. Otherwise you will need
to reprogram the printer as described below. The self test will be repeated until the power is
switched off. Normal operation is resumed after power on.
Loopback Test
On serial versions of the PM1100, when a self test is initiated the board checks to see if the CTS
and DTR lines are looped together. If they are not, then the PM1100 prints "LoopBack :- Not
Present" at the end of the parameters listing. If the PM1100 detects that CTS and DTR are
connected, the DTR line is toggled and this is looked for at the CTS. If the toggling is correctly
detected then "CTS/DTR :- PASSED" is printed. If there are errors "CTS/DTR :-FAILED" is printed.
