Scan from ADF missed content

[cooolll]

Hello.  After formating my pc , i download the software for my hp deskjet 3835 all in one and i install it. 

When i am scanning from flatbed the scanning is ok. When i am scanning from ADF the scanning is wrong everytime. Sometimes i have the half of page, other times i have only the center content of page. I made factory restore on my printer and i update the firmware of printer . I have the same problem. Do you have any suggestion of my issue? 

Thank you

@cooolll Here's what I suggest you do, to resolve this issue:

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, then try to scan. Make sure the original document or photo is in good condition and free of tears, creases, folds, staples, or tape.

   If the issue persists, continue to the next step.

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 the issue persists, continue to the next step.

Hello.  I try first to disconnect every cord from the printer as was on.  After I connect only power cord and made factory reset two times and everything works properly. Thank you from your support
