Remove each cartridge, wipe the chip with a dry cloth and re-install them by pushing down until they "click" into place.

Some Ink left Reading as empty

It is possible that a very small amount of ink may be visible when it reads as empty.
This is due to the design of these cartridges and is not a fault.

Ink in the cartridge, but not printing

The cartridge may show as empty or produce faded print despite ink remaining.
Printing stops once the cartridge reaches around 30% remaining ink, which is kept as a reserve.
This reserve cannot be accessed and is used to keep the internal sponge moist and protect the printhead.
This is normal behaviour and not a fault.
The cartridge will need to be replaced.

Printing blank pages / fading on print

If the print quality is poor or no ink is appearing on the paper, try performing 2–3 head cleans/nozzle cleans.
Leave 20 minutes between each cleaning cycle.
If the issue persists, switch off the printer and unplug it for 10 minutes.
Re-install the cartridge and try printing again.
