How do I know when my Canon copy/fax machine is completely out of ink?

Question

2 days ago it started marking on the machine about cartridge, but I thought "okay I'll order some in like 2 days" cause it still has some. Well yesterday a fax was trying to come in for quite a while so I opened the machine, to where the cartridge is at, and I just moved it around(still in the machine) and I closed it back, and the fax came out, ever since that, it has not been marking that it needs ink.

However, I ordered some online today, should I switch it as soon as I get it(I will get it tomorrow) or wait till it marks again?

Answer 1

A friend of mine told me one time to take the cartridge and shake it. If it's low, you may be able to get a couple more days out of it. Sounds like you should probably change it when you get the new one. Good luck.

Answer 2

Just wait till it markes it needs ink again, then change it.
