Sometimes it can be difficult to isolate which cartridge needs to be replaced.  The easiest way check is to run a test print on your printer.  Most printers have a test print or diagnostic print option built into their software.  A test print prints out a diagnostic pattern of all of your cartridges.  If one of the colors is smeared, the wrong color, or faded, you've likely located the problem cartridge.

To run a print test on your machine, consult your printer manual for specific instructions.  Most print tests can be found under the “maintenance” or “tools” menu of your printer.  Alternatively, you can also run a test print within Windows:

1.  From Windows 10, go to “Printers and Scanners.”
2.  Right click your printer and select “manage.”
3.  Then select, “print a test page.”
