HP officejet Pro 8620

[Ben112]

I have cleaned the scanner glass as suggested but I still have a distinct black, vertical line .

[Bob_Headrick]

The spec that can cause the line can be small.  Please clean the thin glass area to the left of the main bed once again.  It may help to get a strong flashlight and hold it against the front of the unit (about the first "e" in Officejet on the front label) nearly parallel with the glass.  

Clean the scanner glass and underside of the scanner lid with a soft, lint-free cloth sprayed with glass cleaner.

1. Turn the printer off, then disconnect the power cord.
2. Lift the scanner lid.
3. Spray a soft, lint-free cloth with glass cleaner, then wipe the scanner glass, glass strip (if present), the white backing under the scanner lid, and the white strip under the lid (if present) until clean, dry, and streak-free.

     CAUTION:

   To protect the interior printer parts, do not spray the cleaner directly on the glass or on the underside of the lid.

   Figure : Clean the scanner glass and under the lid, and any glass or white strips (if present)

   

   1. White scanner lid backing
   2. White ADF scanner lid strip (if present)
   3. Glass ADF scanner strip (if present)
   4. Main scanner glass
4. Reconnect the power cord, turn on the printer, then close the scanner lid completely.
5. Load the original document or photo, then try to copy. 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.
