Minor Experiments in Electronics |
Today's Experiment |
I used to own an Epson 1280. What a great printer it was. So many after-market upgrades are available for it that I'm sure that this printer's usefulness in the marketplace will continue for a long time. I recently acquired a Canon i9100. It beats the 1280 in nearly every specification, except one: banding! After reading about the banding problems about this printer on many web sites, including people wanting to "see" this banding, I decided to create this short page in an attempt to demonstrate. I couldn't believe that my new $500.00 printer was suffering from such a basic problem, but, it sure seems to be. No adjustment in settings seems to make a difference. Before I realized this was a widespread issue, I bothered Canon and they happily replaced my printhead and sent me a pack of Photo Paper Pro to replace what we spent in testing while on the phone to tech support. To their credit, they are always helpful and quick to honor the warranty.
NOTE: All the images are pics of prints. I know that that's sub-optimal, but my scanner's busted for the time being.
It was proposed by Mr. David Franzen that perhaps it was a moire issue, and that I try the same comparison with greyscale images instead of full color. The results follow: As you can see, banding still remains and is MUCH more evident in the i9100 print as opposed to the S9000 print, even using greyscale output only.
Here are the original digital photos as imaged by a Sony
F717 (click to enlarge): These prints were generated the day my i9100 returned home from its THIRD trip to the local Canon service center. Seems they don't want to admit a design flaw exists in the i9100. Please let me know if you have solved this issue on your i9100. Thank you! |
