A positioning device to control the position of a print agent applicator comprises a mount to support a print agent applicator at a load point on the mount; an actuator coupled to the mount to apply a driving force at an actuation point on the mount; and a guide mechanism to guide the mount and supported print agent applicator, under the driving force, to translate along a predetermined path towards a printing drum to form an engaging contact between the print agent applicator and the printing drum.

Print agent applicator positioning devices

A printer includes a photoconductor, a charge roller, and a positioner. The photoconductor includes an outer surface defining a seam region and a non-seam region while the charge roller is configured to rollingly engage the outer surface of the non-seam region. The positioner is operably coupled to the charge roller and includes a discrete step drive configured to maintain a minimum spacing between the charge roller and the seam region of the outer surface when the seam region passes underneath the charge roller.
