FEED and PAUSE Self Test
Performing this self test temporarily resets the printer configuration to the factory default
values. These values are active only until power is turned off unless you save them
permanently in memory. If the factory default values are permanently saved, a media
calibration procedure must be performed.
To perform a FEED and PAUSE self test, complete these steps:
1. Turn off (O) the printer.
2. Press and hold FEED and PAUSE while turning on (I) the printer.
3. Hold FEED and PAUSE until the first control panel light turns off.
The printer configuration is temporarily reset to the factory default values. No labels print
at the end of this test.

Communications Diagnostics Test
The communication diagnostics test is a troubleshooting tool for checking the interconnection
between the printer and the host computer.
When the printer is in diagnostics mode, it prints all data received from the host computer as
straight ASCII characters with the hex values below the ASCII text. The printer prints all
characters received, including control codes such as CR (carriage return). Figure 22 shows a
typical test label from this test.
Figure 22 • Communications Diagnostics Test Label
To use communications diagnostics mode, complete these steps:
1. Set the print width equal to or less than the label width being used for the test. See Set
Print Width on page 75 for more information.
2. Set the printer to
DIAGNOSTICS
. For instructions, see Set Communications Mode
on page 88.
The printer enters diagnostics mode and prints any data received from the host computer
on a test label
3. Check the test label for error codes. For any errors, check that your communication
parameters are correct.
Errors show on the test label as follows:
• FE indicates a framing error.
• OE indicates an overrun error.
• PE indicates a parity error.
• NE indicates noise.
4. Turn the printer off (O) and then back on (I) to exit this self test and return to normal
operation.
Note • The test label prints upside-down.
