A printer includes multiple gear trains, each gear train to pick paper. The printer also includes a print media sensor to detect the presence of print media along a paper path, a user input control, and control logic coupled to the print media sensor and the user input control. Based upon receiving multiple signals from the user input control to resume printing, each such signal following an indication from the print media sensor that paper has not been picked, the control logic to cause a change-over to occur from one gear train to another gear train.
