The Printer picks up multiple paper from the manual feed tray?

The reason is as follows:-- The pad that is responsible for separating the paper has likely worn out and needs to be replaced. The pad is located in the printer where the end of the paper reaches in the tray.You can order and install a new pad without sending the printer out for repair. It is also possible that the paper is wet due to humidity. Make sure the paper is properly stored and that it is “fanned” before putting it into the printer. this will help.good luck.
