The Online/Offline, Tray Select, Status Page, and Cancel keys access
frequently used printer options. The Copy key is available when the
CrownCopy option is installed.
Key Function
Use the Online/Offline key to switch the
printer from on line to off line status. Press
the key once to take the printer off line
when it is on line and once to return the
printer to on line when it is off line.
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.
If a remote console has taken the printer off
line, pressing the Online key on the control
panel will not take effect until the console
puts the printer back on line.
» Note: You must take the printer off line
before using all other keys except the
Status Page and Cancel keys (and the
Copy key if CrownCopy is installed).
