Understanding Test Mode

Use Test mode to verify printer settings, test printing, restore factory
default settings, or enter Dump mode for troubleshooting purposes.
Two test modes are available: Test mode and Extended Test mode.
Using Test Mode
Test mode is a simple sequence of events which requires little user
interaction. Extended Test mode requires more user interaction and
lets you choose which actions you want the printer to perform.
To enter Test mode
1 Make sure the printer is in Ready mode and is loaded with media.
2 Press the Feed and Standby buttons at the same time and hold
until Select Media appears on the screen and it displays the type of
media you are using.
3 Release both buttons. The printer performs a test feed (sensor
calibration), prints, and then enters Dump mode.
The printer is now in Dump mode and it scans the
communication ports. Any characters received on the
communication ports are printed.
4 Press Feed to exit Dump mode.
After you exit Dump mode, the printer returns to Ready mode. For
more information on Dump mode, see
Communication Problems" on page
Using Extended Test Mode
Use Extended Test mode to run additional diagnostic tests, entering
Dump mode, and resetting to factory defaults.
