HP ENVY 7855 Scanning too dark

[driganati]

I see this has been addressed before, however, I just purchased the HP 7855 all in one.  I am having difficulty with the scanned documents coming out very grey and dark.   I've gone to HP help and this forum, and the directions are there to resolve this issue, however, It says to click on the printer icon that is on your desktop.....I do not have one on my desktop, and I have been looking and looking for the correct one to make the changes.  Help.....need good quality scanning.

Welcome to the HP Support Community.

Does this happen while copying too?

Resetting the printer can force some types of scanners to calibrate, which might fix the problem.

1. Remove any items from the scanner glass and automatic document feeder (ADF), then close the scanner lid.

2. With the printer turned on, disconnect the power cord from the printer and from the wall outlet or power strip.

3. Wait at least 60 seconds.

4. Plug the power cord back into a wall outlet.

   NOTE: 

   HP recommends connecting the printer power cord directly to a wall outlet.

5. Reconnect the power cord to the printer.

6. If you have an HP DeskJet 3700 series printer, calibrate the scanner after resetting the printer.

7. Load the original document or photo, then try to scan.

If you can't locate the Printer icon on the desktop, uninstall and reinstall the Printer software.

Let me know if this helps.

Hi, I am having the same issue.   I tried unplugging the printer but it still scans the document too dark.  I am scanning it to an email when this happens using the automatic feeder.  However, when I make a single copy of the document, not using the automatic loader, the copy comes out looking as it should (white).  Please help.

Welcome to the HP Support Community.

Which Printer do you have?

Thanks 🙂

No, when I copy the same document, it comes out as it should look.

Are you able to copy well from the Feeder?

Clean the plastic and glass strips inside the document feeder with a soft, lint-free cloth sprayed with glass cleaner.

NOTE: 

Some printers ship with a document feeder cleaning cloth. If you have the cloth, load it into the document feeder and start a scan job to clean the scanner mechanism.

1. Turn the printer off, disconnect the power cord, and remove the battery if your printer has one.

2. Depending on your printer model, open any top cover, document feeder tray, and scan document feeder cover.

3. Remove any debris such as bits of paper or paper clips from inside the document feeder.

4. Spray a soft, lint-free cloth with glass cleaner, then wipe the scanner glass and the white strip on the underside of the document feeder until clean, dry, and streak-free.

      CAUTION: 

   To protect the interior printer parts, do not spray the cleaner directly on or into the printer.

5. Completely close any covers and trays that you opened.

6. Reconnect the power cord, reinstall the battery if necessary, then turn on the printer.

7. Load the original document or photo. Make sure the original document or photo is in good condition and free of tears, creases, folds, staples, or tape.

8. To avoid skewing, adjust the guides on the document feeder to remove any gaps next to the edges of the paper and the guide. The paper stack should slide easily into tray and not bind against the guides.

   Try to scan. If the issue persists, continue to the next step.

Clean the automatic document feeder (ADF) rollers:

1. Gather the following materials:

   • A clean, lint-free cloth, or any cloth that does not come apart or leave fibers

   • Distilled, filtered, or bottled water (tap water might damage the printer)

2. Remove the original document from the ADF.

3. Turn off the printer.

4. Disconnect the power cord from the rear of the printer.

5. Open the ADF cover.

6. Find the paper pick rollers and the separator pad inside the ADF.

7. Lightly dampen a clean, lint-free cloth with filtered or distilled water, then squeeze any excess liquid from the cloth.

8. Use the damp cloth to wipe any residue off the paper pick rollers and the separator pad.

9. Leave the ADF cover open for two minutes to allow the paper pick rollers and separator pad to dry.

10. Close the ADF cover.

11. Reload the original document print side up in the document feeder tray. Gently slide the document into the printer as far as it can go.

12. Slide in the paper width guides until they are snug against the paper.

    Do not push the paper width guides in so far that they bend the paper.

13. Reconnect the power cord to the rear of the printer.

14. Turn on the printer, then try to scan.

Yes, the feeder scanner copies perfectly.  Your advice on cleaning the printer did not fix the problem.  Can I talk to someone over the phone?
