Draining a Canon cartridge

[ghwellsjr]

It's very easy to drain all the ink out of a Canon cartridge.

Start with a sheet of paper towel (kitchen paper, I believe it is called in the UK):


Fold it in half:


Fold it in half the other way:


Fold it in half again:


And once more the other way:


Now it has sixteen layers of thickness. Fold over the corner of the last fold:


Apply this corner to the inside of the outlet port:


Wrap the two diagonal sides of the paper towel along the sides of the cartridge and secure with a rubber band:

Place it on a surface that can tolerate ink and let it sit for a few hours or overnight. The paper towel will become saturated with ink. You may have to repeat the process to get all the ink out.

You can also use this technique to dry cartridges that you have purged with running water.

An easier way is to blow from the top, the air goes through the sponge out of the outlet and pulls ink out in drips then a foamy stream which in turn pulls ink from the reservoir.

ghwellsjr: Thanks! Your photo step-by-step makes draining cartridges actually look easy.
I just got into the "German" method with my canon printer and this looks like a great way to renew cartridges
when necessary. Appreciate your contributions! -Nick

Isn't capillary action great!!

I inadvertently did this for the first time in my relatively young refilling career the other day. I forgot to cap off the outlet port of my yellow cartridge while cleaning the syringe from the previous color. When I got back to the table, a big yellow spot had formed on the newspaper. Oops. Thank goodness I use enough pages so it didn't make it to the table.

As i have explained in the past, the method of blowing in the top does work BUT remember to check your face before going out as I omitted to do after blowing a red cartridge. Some bemused looks from passers - by probably wondering what I had been up to. I had to hide away for a couple of days until the ink became less visible. Dreadful stuff to remove!!!

Rather than use newspaper or such I literally inherited a foil oven liner (intended to catch drips in the oven of a kitchen stove) which I use to catch ink drips, etc. when refilling. When done any that got on it easily rinses off.

Very useful guide!

I usually change the paper towel one time after 1-2 hours.

How many hours in total you let the cartridges sit with the paper towel?

Should I place the cartridges over the heating radiator?

ps: I am using this method to remove as much as possible distilled water from flushed cartridges.

Thanks

This method is excellent for drying your cartridges very quickly, but be careful because you don’t want to over dry them.

Once you have your paper towel properly in place then 30 minutes is more than enough time to drain most of the water out of your cartridge which will make it ready to be refilled again, but don’t forget to reset the chip before filling.

Here is another view of the same quick drying method..

I made a mistake.

I wrote distilled water without think that before dry the cartridges I insert into the cartridges the pharmacist formula.

So I use this method to remove the pharmacist formula and not distilled water.

Dunno if this change something.

No, no change or use of distilled water necessary. Pharmacist's solution does not need to be flushed with distilled water and you may just use ghwellsjr's paper towel wicking method to remove excess water from the sponge before refilling.
