I have tried printing a document sent to me by e-mail. This came out blank. Ihave also tried printing a document placed on the printer scanner glass and this also came out blank. With the scanner glass uncovered I could see the printer scanner light progressing across the glass as normal. I have not tried cleaning the machine as I don't know where to start.
On printing this page the message came up that my black and white ink needed replacing and on replacing this the printer works correctly. Problem seems to have been solved.
Thanks for your help.
