The Control Panel Keys
The printer control panel has eight function keys. The top row of keys
(Online/Offline, Tray Select, Media, Cancel) is for frequently used
operations. The bottom row of keys is used to navigate menus, select
options, and enter values.
» Note:
When you're in configuration mode (that is, if you have entered
the menu by pressing the Menu key), the printer ignores the Tray
Select, Media, and Cancel keys.
Press the Online/Offline key once to take the printer
off line (the indicator goes out). You must take the
printer off line before using all other keys except the
Cancel key.
When the printer goes off line, the communication
ports are closed, so no new data is accepted. The
printer continues printing until it has finished all jobs
in process. Although jobs continue to compile and
print using the data already received, a job may be
interrupted, causing it to wait for more incoming data
before printing resumes.
When the printer is off line, press the Online/Offline
key once to place it back on line and ready to accept
new print jobs (the indicator goes back on). If a
remote console has the printer off line, pressing the
Online/Offline key will not take effect until the console
puts the printer back on line.
The Tray Select key allows you to select the cassette
from which to draw print media: the standard (upper)
cassette, the optional (lower) cassette, or the manual
feed tray.
