Like most printers, the Canon i9100 printer has a waste ink collection system which allows excess ink to be gathered up. This is used when the printer does things like clean its heads – which really means it just squirts and wastes lots of ink out of the nozzles to try to clean them. I suppose they don’t want to waste paper by printing ink onto paper. Or maybe they don’t want us end users to realize just how much ink they waste during their cleaning activity, and by “hiding” it inside the machine in those waste receptacles we don’t know about the problem until they get full.
For the Canon i9100 printer, you’re alerted that the waste tank is full by the printer flashing 7 yellow lights and then one green.
Here is how to handle it. There is a video at the end as well.
Canon i9100 Printer – Cleaning the Waste Tank
While the term used by the printer industry is waste tank, with the Canon i9100 all it is is a single foam strip which runs the length of the printer. It lies directly beneath the path of the printer head. You can see it if you simply lift the cover of the printer.
You don’t have to take apart your printer. You just gently pull that foam strip out. Wash it thoroughly with water. Squeeze it dry.
There are also a few foam pads beneath where you just removed the strip. Dab those with a paper towel. Slide the ink to the left to get the one that is beneath the ink cartridge “home rest” position.
Now put the long foam strip back into place. You can tuck it beneath the ink cartridge fairly easy if it’s in that home position.
Now you have to do this sequence to reset the printer’s memory about the ink status.
- Turn off printer
- Hold down Resume button and press Power button.
- Keep holding down Power button and let Resume button go.
- Press Resume button 2 times then let BOTH buttons go.
- Green lights will flash and then stop blinking.
- When green lights are solid, press the Resume button 4 times.
- Press the Power button and the printer should turn off, if not, press the Power button once more.
- Your printer should respond as normal.
Here is what the Canon i9100 nozzle test pattern should look like:
If you’re not seeing all of those colors, it’s time to clean the print head itself. I’ll write that process up separately.
