Introdução

If the HP Deskjet fails to produce quality scans or copies, and you have already checked that the scanner glass is clean and that there are no other problems, you may need to replace the Scanner Bar/Light inside the printer. This part is the sensor that illuminates and captures an image of the document you are trying to scan or copy. The steps for removing this part are included in the following guide.
