Making black and white copies with the tri- color ink

[Rajeeeram]

I would like to know if using tri-color ink to print blank and white copies, drain the color ink too much when compared to using a black ink?

Hello @Rajeeeram,

Welcome to the HP Support Forums!

I understand that you would like information regarding ink usage when copying and printing to your HP ENVY 5643 e-All-in-One Printer. I would like to offer my assistance with this today.

When you copy from your printer, the unit will only use the cartridge that matches the Black or Colour copy that you're performing. If you're performing a Black copy from your HP Envy, only the black cartridge will be used. If you're performing a Colour copy from your HP Envy, only the colour cartridge will be used. Therefore, you cannot perform Black copies with the Tri-Colour cartridge.

When you print from your computer, the computer may send the print job to the printer as an image file. Therefore, even if you are printing a black only document, colour ink may be used to enrich the document. Should this happen, you would be using colour ink without even realizing it.

On your computer you can set your printer to Black Ink Only if you do not want colour to be used in black and white documents. However, in order for me to walk you through adjusting this setting, I will need to know what Operating System you're using on your computer.

What's my OS?

I hope this helps clear up any confusion 🙂
