The scan image you have above could be caused by a few different issues but the number one is a power issue. Make sure that the printer is plugged in directly to the wall and not into a surge protector or a power strip. The printer does not share power well and pulls it in large amounts - when it can't get it it throws little power fits and sometimes will not turn on at all. Try another wall outlet and see if you can get it to power on and do a copy. Does the image look any better?

If this does not solve the issue then it may be that your scanner bulb is going and therefore not illuminating the image properly. Call hp and see if they have any upgrade units available - usually refurbished but they come with a 1 yr warranty and are significantly cheaper than buying a new unit from the store. They will also take your unit and pay to have it returned to go to an environmental recycling facility.

I read the whole paragraph and could not find a question, so I will try a few suggestions.
When you scan, select the option to open the scanner interface. It will give you more control on what you scan.

From the flatbed
When the scanner interface appears choose to Preview the scanned area. On the preview image click neat its border and you will see a dotted/ interrupted frame. Play with the borders of the frame to select the area. Intelligent software like Adobe Acrobat rotate the image to right it.

From the ADF
Check the alignment of the paper on the document feeder. Test the first page and see if it is correct. If it is, and all the subsequent pages have the same margins use the ADF If not, maybe you should use the flatbed.

Tip

LPI, PPI,DPI conversions


Here is a conversion chart for DPI (Dots per inch) to LPI (Lines per inch) or PPI (Pixels per inch)

180 DPI................31 lines/inch or 68 PPI
360 DPI................63 lines/inch or 138 PPI
720 DPI................127 lines/inch or 280 PPI
1440 DPI..............255 lines/inch or 561 PPI
2880 DPI..................510 lines/inch or 1122 PPI

If you plan to enlarge your image, it is better to enlarge it when you're scanning rather than in your application. Each time you modify
an image, you lose some quality. Keep in mind when you enlarge a small photo, such as a 35 mm slide or wallet-size photo, you'll need
to scan at a high enough resolution to retain your image quality, but not so high that your file size is too large to be efficient. You must
manually adjust the resolution (dpi) to maintain the same image quality when you resize your image. For example, if you have a 300
dpi 2 x 2-inch image that you want to enlarge to 4 x 4 (a factor of 200%), increase the Scale setting to 200% or change the resolution to 600 dpi.

How can I scan a document then print it with larger print?


You can scan a document or photo or negative film etc.. using a scanner, there a many types of scanners which you can choose as per your requirement. There are dedicated scanners, all in one integrated scanners, or two in one like that.. but if you need it for your professional use or daily use, it's better to get a dedicated scanner not "all in one" since with all in one if the copier fails or fax fails, the scanner will also fail because they are related and built-in integrated.
The process of scanning a document is as follows;
  • > Place the document on the scanner's flatbed.
  • > Press scan button or scan using the integrated software from the computer.
  • > Customize the scan settings/quality.
  • > Save the scanned documents.
Printing a document to a larger size is different, you can use photo editors like photoshop, paint.net etc..where you can changed the resolution as well as the size of the image. It's best to change the size or resolution before you give the print command. Or you can also change the print size with the paper size or print size.
If you still need more help, please let me know with more details. I am ready to assist you.

Good luck.

Thanks for using FixYa.

Xerox Documate 152 - Scan quality is now V.BAD!


I would go to Xerox.com and look up their knowledge base. Here is a copy of data from their site related to this problem:

Symptom: Scanned images have poor image quality, are fuzzy, unclear, or hard to read.
Cause: There are several things that can lead to poor image quality including the scan settings, dirt on the scanner, and driver problems. Solution: Note: If you scan as a PDF file and your scans look fuzzy when viewed in PaperPort, try right clicking on the file and selecting "Open" to open them in Adobe Reader. If they display fine in Adobe Reader then there is nothing wrong with the scans, it is simply that they are not being displayed well in PaperPort.

The following solutions can help resolve poor scan quality.

Solution 1 - Adjust the scan settings

Try increasing the resolution of your scan. 300 dpi to 400 dpi should be clear for most images
  • If you are scanning in Black and White, try Grayscale or Color. Some images will not display correctly in Black and White
  • You can also try adjusting the brightness and contrast
  • Note: For information on adjusting your scan settings, refer to the user guide for your scanner
Solution 2 - Clean and Calibrate the scanner

Note: Calibration only applies to sheetfed scanners.

Use the link below for instructions on cleaning and calibrating (if applicable) your scanner:
Solution 3 - Reinstall the scanner driver Select a link below for instructions on reinstalling your scanner driver:

HP4400c Yielding Poor Image quality


I was having the same problem- dpi didn't have any effect.
Changing the SHARPEN to "High" and Descreen worked for me. My research showed the alternative fix was a new scanner, or at the very least a new bulb/power supply (which would probably cost more than a new scanner)

Scanning problems


The following came from HP's site. I have also included a direct link for troubleshooting to your model if the following does not help at the very end of this post.
Hope this helps!! :)
Scanned image quality is poor
  • A dirty scanner glass (fingerprints or smudges) will slow down performance and will affect scan quality because the unit is scanning the smudges on the glass. Turn off the unit and clean the glass with a soft cloth or sponge slightly moistened with a non-abrasive glass cleaner.
  • Reinitialize the scanner by shutting down the HP all-in-one and then unplugging the power cord. Make sure that all originals are removed and that the scanner glass is clean. When the power is reconnected and the HP all-in-one is turned on, the scanner will recalibrate.
  • The video driver and video settings on the computer may slightly change the image appearance. The HP all-in-one scans in 24-bit color. Setting the video display settings to less than 24 bit or 24 million colors will result in a loss of color information when displayed on the computer monitor. The video driver itself may change the appearance of colors when viewed on the monitor.
  • Changing the image size will affect how the scan appears. Resizing the scan may make the image fuzzy. Resize the image in the destination or make the original smaller.
  • When scanning an image, save it to a different file format. For instance, save it as a JPEG or TIFF file. When saving a scan as a JPEG, there is often an adjustable quality or compression setting. If the scan is to be used in Windows (such as in a screen saver or for wallpaper), the scan must be saved as a Windows bitmap (.BMP).
  • The destination can represent colors differently than they appear in the original. If the destination is the image editor, modify the colors in the image editor.
  • Make a copy with the same quality settings. If the copy looks better than the scan, the imaging software may be affecting the scan quality. For example, Adobe PhotoDeluxe supports printing at 300 x 300 dpi only, even though the all-in-one product is capable of 600 x 600 dpi. Some versions of Adobe Acrobat change images to either 75 or 150 dpi, depending on the version.
  • Some image editors also convert the file into their own format or use a different default format resulting in loss of quality during the conversion process.
