This is typically caused by an incorrect selection made during the LCD prompting after a cartridge is replaced.

When an ink cartridge(s) is replaced, the LCD will ask, "Have you removed Blck? 1 Yes  2 No". This question will be asked for ALL 4 colours in sequence, regardless if the colour was replaced. If "1 Yes" is NOT selected for the colour(s) that was replaced, the LCD will return to "Ink Empty".

Do the following to clear the message:

1. Open the Scanner cover by pulling up on the edge of the scanner just above the LCD.
    
    
2. After 15 seconds, re-close the Scanner cover.
    
3. The LCD will then display Have you removed Blck? 1 Yes 2 No. The LCD will display this question for ALL 4 colours (not just the ones replaced). BE SURE to select 1 YES for each ink cartridge that was replaced. If 1 Yes is selected, the LCD will then display Change to new (colour)? 1 Yes 2 No. Again, BE SURE to select 1 YES.

   "Change to new (colour)?" will only appear if 1 Yes is selected for "Have you removed (colour)?" If 2 NO is selected for the "removed" question, the LCD will then move on to the question for the next colour.

4. After all the correct selections are made, the machine will then go into a cleaning.
   Once the cleaning is complete, the LCD will return to date and time.
