Product: HP ENVY 7645 e-All-in-One Printer

I am using a 7645 printer to scan.  When I use the auto feed tray, both PDF and JPG documents come out with triple lines vertical lines down the pageIt is as if it were printing side by side pages.  This does not happen when using the glass.  Thus it is caused by the auto tray roller feed mechanism.  Is there a cleaning solution for this problem?
