Check that a toner cartridge is installed and fully seated.
On HP II/III and IISi/4Si models check that at least one
sensitivity tab is installed on the right side of the toner
cartridge. If you see 2 holes and no square plastic tabs sticking
in at least one of them, the printer will not see the cartridge.
If one tab is installed and the printer still doesn't recognize
the cartridge, try popping out the tab and putting it in the
other position.
On HP 4/4+/5 printers the high voltage contacts can be dirty
or misaligned. If contacts are ok, replace the high voltage
power supply.
Error 16 Toner low
Toner cartridge is low on toner. Try gently rocking the
cartridge to redistribute the toner. This will buy you 50-100
pages. Get a new cartridge as soon as possible.
Dirty or misaligned contacts on the high voltage power supply.
On the HP II/III printers it can be a loose connector on
DC controller see tweaking for instructions on how to repair
it.

on the left side of the printer. You have to remove the left
panel and you'll see it. It's located at about the exact center
of the printer.
