Canon I965 waste tank almost full - how do I clean/empty or clear

Canon printers have a waste recepticle bin that catches the overflow ink which is used to lubricate the print heads. The print heads need to be primed to stay wet for the printer to work on command. When the overflow tank is full, you get the warning notice that you mentioned in your question on Fixya. It means the tank needs to be removed & a new empty one should be installed in its place in order for printing to continue.

To solve this issue, you need to contact Canon's customer service department. You can request service on the printer & have them replace the waste recepticle, or you can order the part with replacement instructions and complete the task yourself. Their are disposal instructions that need to be followed for the used ink in the tank and Canon can provide them when you contact them.

Good luck!

According to the user's manual, "Ink used to clean the print head is absorbed by the waste ink tank. When this message is displayed, the waste ink tank needs to be replaced, or the machine requires maintenance". There is no information about how to replace or empty the waste ink tank.

In any case, you can try the following to clear upo the error, but eventually you'll need the waste tank to be emptied or replaced.

Turn on your MP130.
1) After that press: Menu - Scan - Copy - Scan or Menu-Copy-Scan-Copy-Copy in some models, it depends on the date it was produced)
2) Select TEST MODE.
3) Enter NVRAM ACCESS
4) Select SET ABS-M LEVEL TO 0
5) Select OK
6) Keep selecting OK untill you leave the TEST MODE
Then turn it OFF and again ON. Check if the error message is still there

The following is taken from the Canon website, regarding this specific error:
"Canon recommends having the printer serviced before the absorber becomes full. We are aware that there are many "do-it-yourself" Web sites that offer instructions for making this repair. Replacing the ink absorber is a complicated and potentially messy procedure. Even if the ink absorber is successfully changed, the ink absorber counter must be reset. Be aware that if you attempt this procedure, it is at your own risk."
As I mentioned before, I have not found any way or procedure to replace the waste ink absorber nor the necesary replacement part

What I have started to do is to actually wash the toner tank out with water and make sure it is good and dry then be sure the section that breaks the light sensor is good and clean (it is on the left side as you look at the backside - the side that goes toward the printer - and protrudes out) the tank full indication comes on when the tank gets dirty
