The LCD display language can be changed to show any of 14
different languages. (See “Changing the display language” on
page 10.)
R EAR VIEW
This view shows the connection panel, the rear output stacker
and the location of the optional duplex (two-sided printing) unit.
* The Network Interface has a protective “plug” which must be removed before
connection can be made.
When the rear paper stacker is folded down paper exits the
printer through the rear of the printer and is stacked here face
up. This is mainly used for heavy print media. When used in
conjunction with the multi purpose feed tray, the paper path
through the printer is essentially straight. This avoids bending
the paper around curves in the paper path and enables feeding
of up to 203g/m² media.
