Supply System Problem

[tsl4]

There is a probelm with the supply system. 

Try replacing the attected cartridge with a different, non-empty cartridge. 

If message reappears again, record.

I replaced all cartridges and it continues to say that the black cartridge is empty and gives me the above error message.

Welcome to HP Support Community

I suggest you perform a printer reset

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed
