Hi gsahoo0621,
The PIXMA TS6320 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 TS6320 will combine the cyan, magenta and yellow ink tanks together to make a composite black.
To use only the black ink tank, the original text must be black and the paper setting must be set to Plain Paper.
