She could not print yellow. All the other colors would print fine, which truly baffled me because the only true colors are cyan, magenta, and yellow. For instance, green is a combination of cyan and yellow, but green printed fine.
Every color of the rainbow printed fine except for yellow. I had the customer change ink cartridges. I had the customer delete and reinstall the drivers. Nothing worked. I asked my co-workers for help; they offered no new ideas.
After over two hours of troubleshooting, I was about to tell the customer to send the printer in to us for repair when she asked quietly, "Should I try printing on a piece of white paper instead of this "yellow" construction paper?"
