Ink System Failure is a generic error that can mean many things, it could be a symptom of a hardware failure, or it could be a false alarm that you can fix my re-initializing the ink system. Try the following reset and see if the error clears. If not, your printer may need serviced or it is usually a better idea to replace due to the low cost of new printers these days.

Press and hold the "*" key

Press the "#" key and release both keys.

Display should say "Enter Special Key Combo"

Press and release in sequence the "1", "2" and "3"

Press and release the right arrow button until the
display says "System Configuration Menu"

Press and release the "OK" button

Display should say "Hardware failure status". If
not there already, Arrow Key over to "Hardware failure status",

Press and release the "OK" button.

Display should say "Hardware failure status:
Clear. Press OK to clear".

Press and release the "OK" Button. Message changes
to "Hardware failure status Cleared. Press Cancel to continue".

Press and release the "CANCEL" button as many
times as necessary, so that, either the "Welcome to Photosmart Express" screen
appears, or, the "Ink System Failure" screen appears. PLEASE DO NOT TRY TO

Using the Power Button, turn the unit OFF and
unplug the power cable from back of the printer and wall outlet.

Wait 30 seconds for the power to get discharged
and then plug the power cable into the wall outlet first and then into the back
of the printer

Turn the unit on. The printer may display message
Press OK. The Printer will start the "ONE TIME INK INITIALIZATION PROCESS".
Allow this process to complete and do not interrupt. Once the initialization
process is complete, the printer will print out a Diagnostic Page.

At this point, either the error will return, or the printer should function again. Hopefully it will resolve your issue. Thank you.

I press "*" and "#" nothing happens?

Try unplugging the printer for a couple minutes, then plug it back in and see if you can hold * and press # and then enter maintanence mode by pushing 1 2 3.

Another reset you could try is to unplug the printer, then press and hold the # and 6 keys while you plug it back in.
