Hi,

I am sorry, however this error is no related to print head. So, why did you replace print head?

This error means "Ink Detection Waste Ink Tank Full"
You need to replace the ink pad and reset the eeprom counter to 0.

You could try to reset it :-

1. Printer ‘on.’
2. Press: “Additional Functions” button
Press “Scan” button
Press “Copy” button
Press “Scan” button
3. Now it says, “Service Mode / #1 SSSW.
4. Keep hitting “+” [which is the right arrow]; it will go through #1 to #11 (Date/Time), then “Service Report,” and, lastly, “Test Mode.” Then hit “Set.”
5. Now you will have another set of selections. Keep hitting “+” [the right arrow] to go from #1(DRAM) to #8 (Printer Test). Then hit “Set.”
6. When it finishes some sort of function, “Please Wait” will be replaced by “-8-2+” Then hit “+” and it should then say “-8-3+” and you hit “Set.”
7. The screen should now say “EEPROM Clear.” [You may need to press “Set” then, to get to the next step? My notes aren’t clear.]
8. Option 0 should be “select ink count.” Press “Set.”
9. Press the “Stop/Reset” button.
10. Press the “On/Off” button.
11. Wait for the printer to restart.

You could have the complete service manual from :-
