I am sometimes getting complete Blank Images whenever I try to scan on the Lexmark MX310dn scanner from one particular PC. There are two PCs in the office. Could it be that I would need to clean the scanner? The documents are being scanned from the Automatic Document Feeder (ADF) scanner. I have cleaned the scanner and since there are two computers in the office, I also tried on the other one and it seems to work fine. I have then tried on the one which was scanning Blank Images and it seemed to work afterwards. By any chance, does anyone know why this is happening please?
