Question about HP Officejet Pro L7780 All-In-One InkJet Printer
What could casue a white line about 2 inches in from the right border that goes down each page?
Thanks for your help.
TheaDG I have the same problem only my line is blue. I tried cleaning the glass to no avail. Any other suggestions?
I chatted with HP and they told me to clean the ADF frame which had some dust particles on it. Problem solved.
