There is a staple jam.


A single-page job was sent to the Stapler; it will not be
stapled.


The Stapler ran out of staples.


Check the power cords (see page 29).


Check the C-link cables (see page 29).


Make sure that the device has been configured in the
printer driver.


If the printer still does not recognize the device, contact
a dealer or authorized HP service provider. See the user
guide for your specific HP LaserJet printer for service and
support information.


Make sure that the power cord is firmly plugged into both
the device and the power box (see page 29). Remove and
reconnect the power cord.

page 29), and turn the printer on.
