Scanning resolution of multi function laser printers??

HI All

My old faithful Samsung laser printer finally wore out. Im looking to replace it with a multi function laser printer. I want to spend under 200 dollars. At this price will the scan resolution be the same among the different brands?

Just a few days ago I used a friends canon mg3222 printer/scanner to send can a few papers. I copied it to my hard drive and it didn't look that crisp. The specification for that scanner is 1200 x 2400dpi and interpolated its 19,200 x 19,200. By the way this canon was a inkjet multifunction printer. What would be the best resolution I could get in a less than 200 buck multifunction laser printer?

thanks

are you looking for color or b&w printing?

The resolution between scanners does vary some, but the bit depth and sensor type probably vary more.

In practice, you're almost never going to need to or benefit from scanning at over 600dpi, 300 dpi is often enough. Interpolation combines multiple images of the same thing to boost resolution. I'd argue that in practice the sensor's native resolution (resolution it can capture in 1 pass) is more significant as it has a big impact on scan times. Unfortunately, you can rarely find this spec.

HI Jkee

Im just looking for a black and white scanner. Actually, I needed to send some important forms to the Department of Defense. I actually tried using the scanner at the library but the DOD refused them because they said the pages were blurry. I then had a friend bring his canon inkjet multifunction printer over and scanned these pages to my computer. When I examined them they weren't exactly perfect.
That's the reason for my inquiry. Is there such thing as a perfectly scanned copy? One that looks as sharp as the original? The Canon seem good enough, but if I purchase one id like it to look as crisp as the original.

thanks

For that crisp look I keep an HP 7400C around. 2400 by 2400dpi with 48 bit color. Has a USB connector.

It sounds like what your seeing is more the settings then the scanner I would think. I deal with this type of thing at work frequently. I would agree you probably don't want to interpolate, you want native resolution. Settings are hard to do without sitting down and reading through them and trying multiple times.

Also remember what you are seeing on the screen by default is almost always a scaled version. Zoom to 100 % to really judge clarity.

How are you submitting this form/document? Email, website, etc.?
I suspect the method for submitting the form imposes a size limit on what you can submit, scanning at super high resolution isn't the answer.

If the form is available as a PDF or word document you could actually fill it out on your computer using acrobat reader or foxit. This would beat any scanned option. There are ways you can still put a signature on a document like this.

If you could post a small piece of the scan of the form that doesn't contain any personal information (eg. just text found on the blank form), it would be easier to offer suggestions about settings to try.

I think it is something you are doing scans at 600 dpi are more than enough and usually 300 for the DOD
are you doing a SF86 or form from Equip?

They usually want the forms as a PDF so that could be your issue.

Ok lets get down to the nitty and the gritty. I purchased a Samsung 2070 laser multi printer today. I scanned the same document. Supposedly this printer was capable of 1200 x 1200 dpi. But, in the printer software all I could get was 600 dpi. The scanned document of the Samsung was a lot better better than the Canon but not anything close to the original.

My final question. Can a letter scanned at 600 dpi look as good as the original??

yes no reason you cannot I do it all the time, I have scanned more sf86s than you can count along with eqip. I also do mystery shopping so I scan receipt. At work I scan documents for I9s so ssn cards drivers license as well as birth certificates etc.

You might want to look at the quality of what you are printing out to scan.

I will post some examples later today.

600 DPI should have them looking crisp. What kind of format are you saving it in? What's the size of the file? My guess if you're saving it in some super compressed format.
