Canon BJC-3000 - Manual (Page 182)

182 Troubleshooting - Printout is Unsatisfactory
Colour document printed in monochrome
Check 3 Correct printer driver selected?
If the wrong printer driver that only supports monochrome printing is
selected, all the documents are printed in monochrome.
Start the print job again and check that "Canon BJC-3000" is displayed in
the Name entry box of the Print dialogue box.
If the name of another printer is displayed, click the down-arrow and select
"Canon BJC-3000" from the pull-down list.
To avoid this problem, you may find it convenient to set the BJC-3000 as
the default printer.
