If you don’t have the front panel opened, the Pro-100 will not operate, and you’ll see an error message on your computer screen. You’ll need to fold down the lower front panel to extend the output tray to receive the prints, as shown in the above image. There’s a second interior upper lid on the Canon Pro-100, giving you access to the ink tanks and the print head. You’ll lift the top lid to load paper into one of two paper guides. The only buttons are on the far right, and we’ll discuss those buttons in more detail. There’s no LCD screen, no glasstop scanning bed, no memory card slot, and no control panel filled with buttons. The front of the PIXMA Pro-100 is as basic as you’ll ever see for a photo printer.
