PIXMA MG5751 Color cartridges run out without any use

[Gokturk]

Hi, 

I have a Pixma 5751 printer which I almost only use for B&W document printing. Even though I use grayscale printing almost all the time, the color cartridges run out at the same time with the black ones (no exaggeration) So everytime the blacks run out, I also have to change the color cartridges too as their level also appears as empty. Is there any diagnostic test etc. I can perform myself before sending the printer to technical service? and also is there a kind of log that shows the ink usage of the  printer for the number of prints it has used in a certain period of time?

Thanks..

Hi Gokturk,

The PIXMA MG5751 will use color ink tanks to print colored text. Even if the grayscale option is checked in the printer driver, if the original text is in a color other than black, the PIXMA MG5751 will combine the cyan, magenta and yellow ink tanks together to make a composite black. This is why your color ink cartridges are still being used.

To use only the black ink tank, the original text must be black and the paper setting must be set to Plain Paper.

Thanks  a lot for the explanation Patrick,

Is there anything I can do to save on the color cartridges? I wouldnt mind having a low quality black in my b&w document  prints.

Best regards.

Hi Gokturk,

There is a common misconception that "grayscale" is the same as "black-and-white."  While grayscale looks black, it uses color ink to simulate black.  Disabling grayscale will allow the printer to use black ink for text. 

Also, if you are printing less than once a week, I recommend turning the printer off.  The printer will perform a purge to refresh the printhead every 60 hours or so of disuse.  This process does consume ink that can then not be used for printing.

Am running into similar issues on Pixma 870, as well as an HP Envy printer. 
Virtually all printing is on grayscale mode - very rarely print color.

Do most Canon models use color ink to print black and gray ??

TIA

Greetings ,

You are resurrecting an 8-year-old topic, for a product that is different than your own. 

You've also started multiple individual threads for your printer model.  It would be a lot easier for us to assist you if you kept all of your questions in regards to your printer in one thread. 

Thanks in advance.  

Here is a listing of your topics. 😉
