System and method for applying primer to different sizes of media in inkjet printers

A primer applicator for an inkjet printer comprising:

• a supply of primer;
• a stationary roller fluidly connected to the supply of primer;
• a second roller positioned parallel to the stationary roller;
• and
• an actuator operatively connected to one end of the second roller, the actuator being configured to move the second roller bidirectionally in a cross-process direction parallel to the stationary roller over a media transport path.

A method for operating an inkjet printer comprising:

• operating a media transport to move a plurality of media sheets through a print zone opposite at least one printhead in a process direction;
• supplying primer to a stationary roller positioned opposite the media transport and before the media sheets pass the at least one printhead;
• and
• moving a second roller bidirectionally in a cross-process direction over the media transport, the second roller being positioned opposite the media transport and before the media sheets pass the at least one printhead.
