HP updated the firmware in September 2024 on all models that use HP 305 series ink cartridges if the auto-update was on. (most models would have updated)
However, we now (Oct-24) have the latest Premium 305xl cartridges that hold 18ml of black and 18ml of colour (6ml per colour).
These cartridges have a new Electric patch which will give ink levels and work with this latest update.
Remember the original HP 305XL Black only has 4ml of ink and the HP 305XL Colour holds 1.25ml per colour.
Our premium refills which give ink levels hold = 18ml of black and 18ml of colour (6ml per colour)
We always keep the updated items on all our products to work with these aggressive updates
If you need any help, please contact us.
