Ink absorber error 5B00 on MP980 procedure not working

Hello,
The standard procedure indicated for resetting the Canon MP980 does not work. The 5B00 error persists.
- Two solutions:

• Find a working procedure. Canon's solution is to throw the printer away and buy another one. It's a commercial way to renew their stock. And I especially love it; don't bother changing the absorber, it's highly toxic. I reminded them that there are rubber gloves, masks, and even asbestos removal suits on this planet.

Poor us! What a society!

• Another solution is to find the sponge, clean it, and put it back in place. But the question is, where is the sponge? Does anyone have an exploded diagram of this MP980 printer? Moreover, this will probably not remove the 5B00 error message.

I used the Canon_Service_Tool v1.50 and I see
Absorber: Main counter value: 0
Waiting liquid counter: counter value 0
So everything is at 0 and the 5B00 message still appears!
Does anyone have a solution?
Thank you for your help.
