hp 70 lg ink not regconize

[rubensanchez01]

I had spent over 2 hours & could not replace the hp #70 lg ink, even with 2 brand new,
waranty  21/12/20 inks.

Z3200 44" keep saying   missing ink,    or faulty ink..... I cleaned the printhead, check lg airtube,
turn on & off many times, also reseating formatter board. still no luck.

what else I can try ?hp 70 21/12/20 expiration.

I had found the solution to this problem on google search & now printer is working fine..

another lesson learned.
this was what I found

How to reset the printer’s memory:

Remove your new cartridge and replace it with the old one.
leave your printer and go do something else for 10 minutes.
Replace the old cartridge with the new again. These two steps alone often solve the problem, so check if your printer now recognizes your new cartridges. However, if you still experience problems, remove the new cartridge. Make sure you place it in a clean and safe place where the cartridge and the surface will not be damaged.
Turn the printer off using its power button.
Unplug your printer’s power cord. It is important to do both steps 4 and 5 separately because some printers remain in standby mode if you only turn off the power button on the printer’s control panel.
Leave your printer like this for about 10 minutes.
Plug in your printer’s power cord again (but do not immediately press the power button).
Insert your new cartridge.
Press the power button on your printer. The issue is probably resolved.
