I think your batch's thickness is high. so that when you are keeping your batch on the scanner then your cover will be not covering properly. so that the external light will be passing through the gap between scanner and cover. so that your scanning is showing black. if you want to scan your batch, then you have to cover by plane paper around your batch on the scanner. otherwise you try to protect out side light on the scanner glass. now you can get proper scaning.

I am scanning A4 size pages but the when I open the scanned PDF they open in legal size so it is smaller in size. Please help...


Hi Smitha



Look its due to settings only. Hence check to make sure the default paper size choosen by you is A4 and not legal. Because that ever the size you provide it scans to it. If still problem persist the try to email me the correct model number on the printer.

How to have white background on small documents


All areas outside of the document will be black only. I don't know how you were getting white background.
If you want white background around your scanned image, a) stick the check (in this example) onto a white paper and scan the whole sheet. Ensure double detection is off. b) You can also do this in software, by cropping a larger area outside the scanned image.

There are many options to view the scanned image like Actual size or Fit or Fit vertically or Fit width. The same image will appear different in each case.

Scanned images are scaled


the feed rollers likely have paper dust accumulation and are slipping .. you can clean them with special cleaning fluid or just water .. dont use alcohol since that can remove elastomers that give it traction ... since you have so many pages thru the machine then the rollers may be warn or hardened and need replacment ..

Faulty scanned images


Pls check your color Scan settings. Generally there will be some color difference between the original and scanned Image because, the original is 'reflected light' whereas, the scanned image is a 'source light' on the monitor. The monitor setting can also affect the color output. S. Mohan

Lines when scanned


The common solution on this sight to this problem on any copier seemed to be simply clean the glass. I first cleaned the glass on the bed...no help. Then I lifted the feeder and discovered a portion of the glass under that as well. Once it was cleaned the lines disappeared!

I saved $$ on a useless service call for a simple, easy to fix problem thanks to this site!

Scanned documents are very light


I have found that when scanning b/w documents, its helpful to start with a black and white copy, not a grayscale, pen written, or printed form a printer in grayscale mode copy, but a true black and white on the copier or fax copy. The scanner doesnt read shades of black so well and when scanning multiple page documents, my pixma tends to scan in lightly. I havent found a piece of software to do just this, batch darken what has been scanned (at least not for free). Copying before scanning is the work around. Hope this helps everyone who's had this problem. It also doesnt hurt to darken what your scanning down a notch when copying
