The waste ink tanknear full how do i empty it ??

The waste bin full error can occur if the waste bin was not removed from the machine for over 10 seconds when it was emptied. Please remove the waste bin and wait for a full 10 to 20 seconds before replacing the Waste bin.

If the message still displays turn off the machine and leave it off for 1 minute then turn the machine back on.

Then run software update to make sure you have the latest OS updates.

Then delete the printer and re-add the printer.

When the printer is not being used, the print-heads slide to their "resting" position,
in order to keep the ink-jets moist, i.e., to NOT dry-out.

Some ink is absorbed into that INK-ABSORBER.

Now, after a few years of usage, that ink-absorber is "full".

Like taking-out the garbage from your kitchen waste-basket when it gets full, and replacing the full waste-basket with an empty waste-basket, it's time to get your printer serviced -- replace the "full" ink-absorber with an "empty" ink-absorber.

Note that CANON printers do not actually "measure" the fullness -- they electronically estimate the fullness, given information about how much you print, and how often you print, and the "density" of the pages that you do print (text is much less dense than colour-photos).

The waste ink absorber can sometimes be removed and cleaned out and put back into place. Although it is not always easy to get at. Usually once this happens it is time for a new printer. You can also contact Canon and see if they have a replacement part for this.

If you peel apples, the apple-peel becomes "waste", and you put the waste into a bin. When the bin is full, you have to do something, i.e., empty the bin into a composter, or send the bin to the land-fill, or you get another bin.

Similarly, when your printer "wastes" ink, the ink is retained inside the printer, until the waste-absorber unit becomes full.

Take the printer to a qualified technician, to either "empty" the bin, or to "replace" the bin.

You can't empty that one, you need a shop to replace the pads which are under the printer, and they can reset the waste ink counter at the same time.

The POWER Lamp Flashes Orange Eight flashes: Waste ink tank almost full
The printer has a built-in waste ink tank for the ink used during print head cleaning. Eight flashes indicates that the waste ink tank is nearly full. Press the RESUME/CANCEL button to cancel the error so you can continue printing. Before the waste ink tank becomes completely full, contact a Canon service representative.

Note
Canon recommends that you call for service as soon as this error occurs. Once the waste ink tank becomes completely full, printing will no longer be possible.

you can not empty it without going to service centre?

Inkjet printers have a fibrous pad inside them that collects the waste ink from cleaning the print head. Over time, this pad fills up with ink and can no longer hold any more. When this occurs, the printer indicates a "waste ink full" error.

The waste ink absorption pads cannot be emptied, only replaced.

Replacing the waste ink absorption pads is something an authorized canon service facility can take care of for you. Once they are replaced, it'll be functional again.

Waste absorber is full. Where is the waste ink absorber and how do I empty it?
