Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
All we should have to do is reset the waste ink counter, and you should be able to continue to print..
Heres how to do so Frank,
Canon i850, i950, S600
Start with the printer OFF
1. Hold down RESUME and then hold down POWER
2. release RESUME
3. press RESUME twice, then release POWER
4. Let green light blink until printer is done loading into service mode.
press resume 3 times. Then press power
That should reset the waste ink absorber, the machine should restart and the error should be gone.
If you get stuck or run into any issues completing these steps let me know!
