The Canon ImageFormula DR-C225was somewhat average in our scan quality testing, picking up a score of 6 out of 10. In terms of printed text and handwritten text it was quite good, with the resulting PDFs looking nearly as good as the originals. It tended to make receipts look a bit smudged and washed out, but it never made any part of any receipt look illegible. It mostly lost points due to its color scans, which came out looking overly saturated and dark, often making graphs and figures looks a bit blacked out. The Canon ImageFormula DR-C225's main competitor, the Epson WorkForce ES-400, scored an 8 out of 10 in this metric. It was significantly better in scan quality with near perfect digitization of handwritten text, printed text, and receipts. It also did a significantly better job handling full color documents, with all the shades looking much more natural and true.
