How do you fill HP88 cartridges? Answered

 If I can fill HP88 cartridges, how do I make my printer (HP Officejet Pro L7780 All-in-One printer)show a full level of ink?


I had a friend that used to keep a full cart. around just to get the printer started after he refilled one.  He would refil, then reset the printer with the full one, then stop the printer and change out the cart for the refilled one.  It was an older Epson and it didn't check to see if the print cart had been switched.  I doubt that this would work with your HP.

There are cartrige reset devices available for most printers that need the chip reset.  Then you refill your cart and reset the chip then insall just like a new cart.
