TEST Key

under the Test Print menu (see page 89), by pressing the TEST
key. To stop the test print, press TEST again.

SHIFT Key
This key does not have a function of its own. It is combined with
other keys to modify their functions.
PAGE EJECT Key
The PAGE EJECT key performs the following functions when the
printer is online:
When the JOB IN PROCESS status indicator lights steadily,
pressing PAGE EJECT causes the printer to print all data in the
printer. The page is then cut at the perforation (unless the Burst On
Eject option is disabled).
IMPORTANT
Do not press PAGE EJECT while JOB IN PROCESS is flashing,
or your print job might become misaligned.
When the JOB IN PROCESS status indicator flashes, pressing
PAGE EJECT causes the printer to attempt to print any data in the
buffer. The paper motion caused by the page eject operation may
interrupt the printing of data that is not currently in the buffer. Once
the paper motion has occurred, the data that was not yet in the
buffer should print. The page is then cut at the perforation (unless
the Burst On Eject option is disabled).
