My Cannon ip pixma 2000 is saying that the waste

The waste ink absorber is actually a pad/sponge that absorbs left over ink spray. There's really no precise way to measure the amount of ink these pads hold so when the message first appears, "waste ink absorber is almost full" it's just an estimate.

The workaround for the message is as follows:

Reset ip2000 / 3000

1. Turn off printer
2. Hold down Resume button and press Power button.
3. Keep holding down Power button and let Resume button go.
4. Press Resume button 2 times then let BOTH buttons go.
5. Green lights will flash and then stop blinking.
6. When green lights are solid, press the Resume button 4 times.
7. Press the Power button and the printer should turn off, if not,
press the Power button once more.
8. Your printer should respond as normal.

Using the above procedure should clear the message and your printer should function normally afterward. Best of luck and thanks for using Fixya!
