I want to use more than one of the HP LaserJet 3100 product
functions at the same time? This product is specifically designed to
allow you to do many tasks simultaneously, such as print while
sending a fax.
Jobs also queue and wait until another job finishes. For example, if a
fax is being received while you are printing, the fax is stored in
memory and then prints automatically after the print job finishes. Or, if
an incoming fax is being printed, you can start sending an outgoing
fax. The outgoing fax is stored in memory and starts transmitting
when the phone line is available. Only in rare instances will the HP
LaserJet 3100 product run out of memory and cancel one job so it
can complete another.
See “Simultaneous tasking features” in appendix A for a complete list
of which features can be used at the same time.

to try to reprint them.
The memory is full due to an error, such as out of paper, and
someone sends me a fax? The HP LaserJet 3100 product receives
faxes to memory until the memory is full. Once the memory is full, the
HP LaserJet 3100 product no longer answers calls, and the control
panel display shows any error conditions that need to be corrected.
After the error is corrected, the faxes in memory print automatically,
and the HP LaserJet 3100 product resumes answering calls.
If I pick up an extension phone and hear an incoming fax? Press
on the phone’s key pad and hang up. The HP LaserJet 3100
