so i just purchased a canon pixma mg5220 all in one injet. reason i purchased it was due to its "optional" 2400 x 4800 optical scan res. i dont know what that means but it was the most dpi i could get at that price point. after playing around with it, i was unable to locate this optional res but did scan a few images. i noticed at 1200 dpi a grayscal image was 17mb and a color one was like 40mb.

so my questions are:
does anyone use a canon pixma and know how to access the option high res.

does it matter. do i really need to have 2400 x 4800 dpi if i dont plan on blowing up and printing a 4x6 to say an 8x10,

also any info that would help me better understand scanners would be appreciated.

If you take 5 minutes to do a search on this forum, you will find several thread dealing with all you want to know.

Two comments:

• It is highly unlikely that your scanner will produce a true 2400 dpi (the lower number is the only one that counts). Actual performance is probably closer to half that.
• For scanning prints (your scanner will not do negatives), 1200 dpi will allow for 4x enlargement of your original (printed at 300 dpi)

That being said, I have a friend who has the Pixma MG5220 and it performs the general household/small office tasks of scanning/printing in a credible manner. It is a decent all-in-one. Sort of large, but works well for general use.

As for accessing the "high-res" mode, perhaps your user manual might be a good place to look?

thanks for the explanation. just wanted to know that i can have a decent print after enlarging a 4x6 scan to 8x10. i did read the manual and even searched usa.canon.com and google and nothing mentions how to access this option. it mentions it as a feature but not how to access it.

You need to consider for scanning the format of the original. For scanning from film 2400 dpi is the lower threshold. My scanner , a minolta Dimage II is 2880 dpi but this produces approximately a 10MP scan of a negative or slide

Scanning prints, if theyare totally optically produced and scanned from gloss needs only about 600 dpi. Scanning 4" x 6" prints from a digitally processed production needs in the order of 100 dpi because that is all that was used by the processor to print it
