Question about HP Officejet Pro L7780 All-In-One InkJet Printer
I have been scanning papers for months and never had any problems. I scanned a batch this morning. Halfway thru the batch the scannings turned out black. How do I fix it?
I think your batch's thickness is high. so that when you are keeping your batch on the scanner then your cover will be not covering properly. so that the external light will be passing through the gap between scanner and cover. so that your scanning is showing black. if you want to scan your batch, then you have to cover by plane paper around your batch on the scanner. otherwise you try to protect out side light on the scanner glass. now you can get proper scaning.
