Installing the accessory
Preparing the printer
The printer, by itself, measures 16.8 inches (42.7 cm) from front to
rear. To attach the HP LaserJet Print to Mail accessory, allow for an
additional 21.75 inches (55.2 cm) at the rear of the printer.
1 Turn off the printer.
2 At the rear of the printer, remove the dust cover, if installed (not all
printers have dust covers), from the rear of the paper tray by
grasping it on both sides and pulling it straight back, away from
the printer.
3 Remove the two duplexer tabs, if installed, from the rear of the
printer by first gently pulling the bottoms of the tabs straight back,
and then rotating them up and away from the printer.
Note If a duplexer accessory is installed on the printer, it must be removed
to install the HP LaserJet Print to Mail accessory.
