Your inkjet printer may not recognize the correct ink level because the printer memory still contains the level of your previous, empty ink cartridge. To resolve this, try these steps:
- Turn off your inkjet printer and remove all printer cartridges.
- Unplug the printer from it's power source for 5 minutes.
- Plug in the printer, replace the cartridges, and power on your printer.
