TROUBLESHOOTING.
1. THE PRINTER IS NOT PRINTING DATA FROM HOST.
1
. Check the PAPER light. It is OFF when paper is properly inserted in
the printer.
Activate the test function described in step 2. Send data to the IDS
160 from the host device. Print the test report (press the AUX switch).
Print the Configuration data (press the PRINT switch).
2. Check the Received Characters count. If the count is 0 then check
the following: The RS232/Current Loop switches in the IDS 160. The
cable connections between the IDS 160 and HOST.
3. Check the FRAMING ERRORS and PARITY ERRORS count. If they are NOT 0
then the baud rate or data format is incorrect. Verify that the Serial
Port Configuration printed in the Configuration report is the same as
the HOST's configuration.
4. Verify that the mode is correct. The mode that is printed should be
"Mode 0 - Slave Printer" unless you are using a SPECIAL APPLICATION
mode. If you are using a special mode then the meter type will be
printed after the mode. Verify that the correct meter type is selected.
2. MISSING DOT TROUBLESHOOTING.

1. Broken needle.
2. Blown transistor.
3. Blown drive diode.
4. Blown fuse.
The table below lists the dot driver components in order of
dot position. If a dot is missing, check ALL of the
