Why not try it like you did with the inkjet? –  random Jan 20 '10 at 6:29

That was about 8 years ago and the cartridge was around 30$. so i could take the risk but idon't want to risk this 130$ cartridge for that but yes after 3-4 refills i will give it a go. You won't beleive it i put the PEN ink bottle (2$) in my HP cartridge and it worked . I printed around 15000 pages using those inks –  Mirage Jan 20 '10 at 6:35

It would be really great if it didn't print green, but some other color. –  Daniel Beck Nov 12 '10 at 0:20

Yes it will print green. The machine doesn't really "sense" what exact color of ink is inside the cartridge, but some can read the sensor and see if it is the right catridge, however that means nothing if you put a different color in it yourself. It counts on the user to fill them and insert them correctly. It can sense the amount of ink left, however :)

Aren't the cartridges key-coded, to prevent inserting the wrong color in the wrong slot?

For some printers, it's done electronically: the ink cartridge has a small electronic part that tells the printer which color it is, how full it is, whether it's a genuine cartridge or a third-party one ...

Not because they wouldn't work, but to prevent inattentive users putting cartridges in the wrong place and getting confusing results. –  pavium Jan 20 '10 at 6:36

The printer will use the toner you put into the cartridge, but the quality of output and what it does to your OPC drum and fuser will depend on whether the toner has the same characteristics as the regular black stuff for that printer. There is a risk of clogging up these parts and reducing their life if the toner is not fully compatible.

The printer's electronics don't care about the color of the toner. The printer will simply produce printouts with the color of the toner. However, different types of toner may not behave as the printer expects, and this is very likely to cause the printer to malfunction. In particular, the OPC drum, transfer belt, rollers, and fuser may not like getting a different type or color of toner than it expects while printing.

Furthermore, as Simon notes, because of contamination by residual toner in the cartridge, the first [xxx] pages may be colored as a mixture of the two toner colors.

Most of the fairies inside your printer that make it work are colour blind and so will quite happily use the green toner. There are however a small proportion of fairies who aren't colour blind and if you catch one of these on a bad day it will climb out of your printer and crush your testicles between a sperm whale and a bowl of petunias.

I can't help wondering what, other than your print outs being green, do you think could happen?

No it won't be green!

It will be a muddy gross black and green smudgy mess...

At least for the first few (no idea how many) pages
