Hi! Joannakat Thanks for posting in the Canon Community Forum. I see that you have a PIXMA MG3600 series printer and you are unable to print in color from one of your Mac computers.
You mention that you can print in color from your other computer. That does prove (as you suggested) that the nozzles on the color cartridge are not clogged. I do see that you reinstalled the printer driver, and that did not help.
Next, I recommend that you delete the printer from your computer’s list of printers and add a new copy.
Please follow these instructions:
- Click on the Apple icon in the top left corner of the computer screen.
- In the menu that drops down, select SYSTEM PREFERENCES, and then click on PRINTERS & SCANNERS.
- Single-click on the Canon MG3600 series that appears on the left side of the window and make sure it is highlighted.
- Click on the Minus (-) button that is below or to the side of the list of printers, and then select the option to delete the printer.
- Once the printer is deleted, click on the (+) button and open the Add Printer window.
- When the Add Printer window appears, wait a few minutes for the printer to show up. It may show up more than once.
- If it appears twice on the list, click on the printer that appears next to Canon IJ Network. If it appears only once, click on it and make sure that you see “Canon MG3600 series” in the box marked “Use.”
- Click on the Add button.
- Wait for the printer to be added back to the list of printers, and then close the Printers & Scanners window.
When you are done, please try printing something with color again and make sure that Grayscale Print is not checked. If you are still having the same issue, I recommend that you reset the print system on your computer. To do that, please do the following:
NOTE: Resetting the print system will delete all printers from your Printers and Scanners window. If you do have other printers, you will be able to add them by clicking on the + button after the print system has finished resetting.
- Click on the Apple icon in the top left corner of the computer screen.
- In the menu that drops down, select SYSTEM PREFERENCES, and then click on PRINTERS & SCANNERS.
- Hold down the CTRL button on your keyboard. While holding that button down, click on the Canon MG3600 series in the Printers and Scanners window.
- Click on the RESET PRINT SYSTEM option that pops up and wait for the print system to finish resetting. You will see a message when it is finished.
- Click on the (+) button and open the Add Printer window.
- When the Add Printer window appears, wait a few minutes for the printer to show up. It may show up more than once.
- If it appears twice on the list, click on the printer that appears next to Canon IJ Network. If it appears only once, click on it and make sure that you see “Canon MG3600 series” in the box marked “Use.”
- Click on the Add button.
- Wait for the printer to be added back to the list of printers, and then close the Printers & Scanners window.
After the printer has been added back, please try printing again and make sure that Grayscale Print is not checked. If your prints are still not coming out in color and you are able to make color prints from other computers, I recommend contacting Apple for help.
I hope this information helps. Thanks again.
