The lid hinges back slightly to accommodate thick originals but doesn't detach entirely. The scanner lid conceals a flatbed scanner that can hold up to 8.5x11.7-inch originals (approximately A4 size). Despite the smaller real estate, the MP510's control panel offers the same array of buttons as the MP500: three buttons to toggle between Copy, Scan, and Memory Card tasks a four-way rocker switch and Menu, Back, and OK buttons to navigate the various menus a Settings button a Photo Index Sheet button a Feed Switch button to toggle between the input sources and, of course, start buttons (one each for color and black) and a cancel button. The small 1.9-inch LCD is embedded in the underside of the lid, and you can pivot the lid forward and back to optimize the viewing angle (the MP500's LCD measured a much more generous 2.5 inches). The control panel on the Pixma MP510 is more discreet: it sits to the side of the scanner under a flip-up lid that measures about 3.25 inches wide and 4.5 inches deep. On the Pixma MP500, the control panel sat front and center on a shelf. The most notable design change is the location of the control panel. Its boxy body is swathed in white and light silver plastic. It sits 17.6 inches wide, 14.5 inches deep, and 6.8 inches tall and weighs slightly less than 16 pounds.

It's slightly smaller and lighter than its predecessor, the MP500. It lacks fax capability, a feature that's more commonly found on office-oriented all-in-ones. The Canon Pixma MP510 is a photo-centric all-in-one printer that combines print, scan, and copy functionality.

Comparisons to the MP500 aside, the MP510 lacks some elements that are quite common on photo printers, such as the ability to use the PictBridge port as a USB port for external storage devices and the ability to push photo content back and forth between the printer's memory card slots and the attached PC with a touch of a button. It also left out the MP500's built-in duplexer, and the ink system shrunk from five tanks to four (the dye-based black ink was left out on this round). For one, it reduced the LCD from 2.5 inches to 1.9 inches. Canon pulled back on some elements of the MP500.

For one thing, at $150 the Pixma MP510 is about $30 cheaper than the Pixma MP500. Generally, we see quality and technology improvements with each iteration of a product, but that's not exactly what happened with the MP510. Canon's new Pixma MP510 all-in-one is the 2006 refresh of the Pixma MP500, which performed quite well in CNET Labs.
