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.

A black line on the scaned page


If light going around the paper, and if upper white paper don't cover it, this part will be black. Try to cover with some part of white paper around. If you have black line in the middle of scan, you have hardware problem with scanner (or old buggy driver). Try to update scanner driver.

The scanner is reporting an E2 error code when it draws a document in. Any ideas? Re-cycling the power clears error but comes back when I scan. thankyou in advance


Hi,

This error message means ADF front side scanning optical alarm (lower optical unit ADF) which indicates ADF (front) lamp intensity check. Please follow the steps provided below:

1. Is the upper glass (white sheet guide)of the reading section dirty?

Open the ADF, and clean the sheet guide (white part) and the glass.
# When operating the scanner, the ADF’s inside glass becomes very hot. Take serious caution as the heat can cause burns. Before you clean the inside of the scanner, turn off its power and unplug the AC adapter from the outlet and wait (at least three minutes) until it gets cold.Be careful not to pinch your fingers when the ADF cover is being closed.
Note: Cleaning should be done approximately every 10,000 sheets scanned, though it may vary depending on types of
documents scanned. More frequent cleaning is necessary when the following types of documents are scanned:
- Smooth surface document such as coated paper
- Documents printed on almost entire surface
- Documents processed with chemical materials such as carbonless paper
- Paper with a high calcium content
- Pages with pencil lead
- Document where toner is not fused sufficiently.

If the above does not help, then the issue is caused by any of the followings for which you may have to contact the Fujitsu Expert/Engineer.

1. Lower Optical unit ADF may be dirty.
2. Lower lamp may not be functioning properly.
3. The connecting cables might be damaged.
4. The connectors are not connected properly.

Hope the above information is helpful.

Regards,

Black and white scanning, as our scanner scans in colour, I would like to know how to scan in Black in white so to have smaller files. Thanks Sonia


You must select TIFF format for B&W. TIFF G4 format is the smallest. JPG offers both grey and Color outputs.

Cannot get it to scan black and white pencil drawing


Pencil drawings are 'weak', you need to adjust the contrast to get good output. Try different options.

Bad contrast with scanner


Last things first: NO USER SERVICEABLE PARTS INSIDE.

That's the way HP does things. There are no rheostats or pots to adjust. It's all done electronically now, with chips and things.

You never said how it does with color or greyscale photos or drawings.

As for the RGB=(64,64,64), that's about right for the scan picture settings and the mixed (text and graphics) setting, and is particularly true for color picture settings. Have you tried using the setting for drawings (or line art), specifically greyscale drawings? Usually the greyscale lineart or drawing setting will render black text. You might also try scanning with the settings set for Text. If the greyscale drawing settings or greyscale text settings do not produce black text, try reinstalling your software and drivers.

If the contrast stays the same for all settings after reinstalling the software and drivers, and if it doesn't scan color and greyscale pictures correctly, then it sounds like your scanner is going bad.

As for the scans you've already done, you can darken the text by taking it into a photo editor, such as Paint Shop Pro or Photo Shop, and adjust the contrast and brightness to get the effect you desire.

Problem with my A3 flatbed scanner


The preview, if it is thumbnail picture, it is difficult ti decipher. Dont worry about that. Pencil drawings are very light and needs higher contrast. Try a few options and you can select the best one. If you scan a pencil drawing in grey, it may appear light and also file size will be bigger.

The scanner copies three photos as one


Assuming you're using the Epson Scan software, select Home or Professional mode and click Preview. When the preview image appears, draw a marquee around each of the three photos. (Note that as you draw each marquee the number beneath the little image of a marquee - the white square with the dotted line around it - increases.) After drawing your marquees, click the All button, then click Scan. The scanner should make three separate passes in succession, producing three separate images.

Grayblue Background on scans


A color scan will give real output as it is. If the background is grey, the output will also be grey. If you select 256 Color output, there may be small change in color, as compared to the original. If you select grey output, all colors will be converted to Grey. If these files are converted to PDF, it will be same, except in ODF format.

If you select B&W you can save the file in TIFF format. Unlike grey or color, each pixel can be either black or white only. To scan in black and white you must select right brightness. By doing os you can eliminate background (technically noise) and capture foreground(data)

Documents scanned as 256 grey scale/TIFF show up as black pages.


Grey as you know is different shades of black. Uncompressed TIF can store this information. Compressed TIFF is not designed for this. Compressed TIFF is for blck & white only. Try JPG option. JPG can compress Color & Grey. For pure black & white chose TIFF compression.
