This video shows how to resolve streaks or lines on the page when
scanning or copying through the Automatic Document Feeder,
or ADF, on HP PageWide Pro Multifunction printers.
When using the Automatic Document Feeder for copies or scans,
streaks or lines might appear on the copies.
These streaks or lines might be on the front of the page or
on the back of the page for two-sided copies.
The streaks appear on the copy from the top to the bottom of the page.
This area is used when documents are copied on the flatbed glass.
This area is used to scan the front side of the page
when the document is copied through the ADF.
This area is used to scan the back side of the page
when the document is copied through the ADF.
As the original passes across the bottom of the document feeder,
the front of the page is scanned by optics located here, below the small scanner glass.
The back of the page is scanned by optics located here, behind the glass on the ADF.
The original is fed down through the ADF, passes across the small glass
on the scanner and the glass in the ADF, and then moves back into the ADF.
HP data indicates that greater than 99% of the time,
if you have a streak when copying through the ADF,
it is caused by debris on the small glass on the scanner or the glass on the ADF.
Debris might be located on the small glass on the scanner
if the streak is visible on the front side of the copy.
Debris might be located on the glass on the ADF
if the streak is visible on the back side of the copy.
Debris can be caused by paper dust, markers,
Wite Out correction fluid or tape, adhesive from Post It notes or flags.
Clean the small glass on the scanner or the glass on the ADF with a
soft, lint-free cloth moistened with glass cleaner.
Spray only onto the cloth and not directly onto the glass or the device.
Wipe the glass again with a dry portion of the cloth to remove any residue or smudges.
The following are recommended for cleaning: glass cleaner,
lens cleaner with a soft, lint-free cloth or microfiber cloth.
Make another copy.
If the streaks still appear on your output, follow these steps.
On a blank sheet of paper, draw an X in the lower, left-hand corner on one side.
Turn the paper over and draw an O in the lower, left-hand corner on the other side.
Place the sheet of paper in the ADF input tray with the X facing up.
Make a copy of the test page.
If the line or streak is visible on the side of the copy with the X on it,
the debris is located on the small glass on the scanner.
Open the ADF.
Place the copy face-up on the flatbed glass, with the X.
Make sure the upper-left corner of the copy is aligned
with the upper-left corner of the flatbed glass.
The line or streak will point to the area on the glass where the debris is located.
Use your fingernail to loosen debris that might be stuck on the glass.
Use only your fingernail.
Other sharp objects might scratch the glass.
After loosening the debris, clean the glass,
and then wipe the entire area to remove any residue or smudges.
If the line or streak is visible on the back side of the copy,
make another copy of the test page.
Choose the Two-to-Two Sided option from the copy menu.
If the line or streak is visible on the side of the copy with the O on it,
the debris is located on the small glass on the ADF.
Hold the copy against the ADF white backing.
Make sure the upper-left corner of the copy is aligned
with the upper-left corner of the ADF white backing.
The line or streak will point to the area on the glass where the debris is located.
Use your fingernail to loosen debris that might be stuck on the glass.
Use only your fingernail.
Other sharp objects might scratch the glass.
After loosening the debris, clean the glass,
and then wipe the entire area to remove any residue or smudges.
Now, make another copy to verify the streaks are gone.
Cleaning the glass periodically will help prevent
streaks and lines and will ensure great copy quality.
Do not use abrasives, acetone, benzene, ammonia,
ethyl alcohol, or carbon tetrachloride on any part of the product.
These can damage the product.
