Troubleshooting
3-4
The conversion box does not print data coming from the host
• Check that the serial communication connection is correct. The
Status indicator should light when receiving data.
• Check the printer display to verify data is received. If so, try to
eject the page by pressing the Form Feed button of the printer, and
verify that your application terminates the job by a Form Feed
command.
For that, you can run a Hexadecimal Printout (see Chapter 2 for
details).
• Check the serial communication with another working device to
validate it.
Page layout and margins not exactly as expected
• Check the PPL3 / LN03Plus dipswitch setting on the Convert Box.
The two emulations may have slight differences in page margins
and some other functions in some instances.
Page break occurs frequently
• Check the time out setting on conversion box is equal to or greater
than the target printer time out. See Chapter 4 for the default target
printer configuration and Appendix A for information on time out
setting.
• Check the host does not frequently interrupt jobs.
The conversion box time out should always be greater than host
interruptions.
Printing stops
• Check there is paper in the printer tray.
• Check the host computer did not interrupt the job.
Printing positioning is not correct
• Check the paper format setting on dipswitch is correct.
The paper format setting on box dipswitch and printer setup, and
paper installed in the printer should match.
• Check the Specific Conversion Box Commands as given in
Appendix A for more information on the parameters.
