Canon iP870 - Colors printing dark + muddy

[mm0615]

I own 2 Canon iP8720 printers and own a stationery business. This means that I am constantly printing the same designs over and over again so I know when something is printing different and I know how the colors should look.

My one printer is printing dark + muddy. When I print them on my 2nd printer the colors are printing perfectly fine as they should be. 

I can't figure out why one printer is printing the colors so awful. I have used the same settings as the 2nd printer that works and it still prints differently. 

Any help or advice would be greatly appreciated, thanks so much in advance!

Hello.

There may be an issue with the nozzles on that one printer.  Visit THIS LINK for details on how to print a nozzle check pattern.  If the colors come out incorrectly, try performing 1-2 cleanings or deep cleanings to see if this improves the output.

If the issue persists, please provide us with a picture/scan of your latest nozzle check print from the erroneous printer.
