Your scanner's lance (shown as tube light) is weak, change it.

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.

Get a black strip when I try to copy or fax a paper. Able to receive a fax without problems. Replaced drum and cartridge and cleaned what I could see, but strip is still there.


sorry but the drum has nothing to do with the SCAN problem, only for PRINTING problems, if you have a BLACK STRIP when you scan, you must check the SCANNING lamp for obstruction (liquid paper contaminant) on the scanning window or for other debrie that prevent the scanner to scan properly is it a dual feed??? (flat bed or top load)???

Black line in paper


On what operation are you receiving the black line in your paper?

This problem usually appears when you try to scan or copy using your ADF (automatic document feeder).
To remove this black line in your paper, clean the ADF platen glass in your printer and do as well in the flatbed scanner glass. This ADF platen glass can be found right below where the documents in the ADF goes through. Its a glass about 1 inch in with and beside the flatbed scanner glass (the one where your documents is lay down for copying and scanning. Dried ink or paper residue sticked in the glass can cause this line in the paper. Clean it with a a clothe and spray some windex on it.

Good luck!

HP L7780 Scanned images are all black


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.

Try and scan a white paper. If the output is black, then may be the LEDs are not glowing, likely the wire is loose. Actually it is not easily reacheable! Try duplex scanning to check if both scan modules are fine.
