In one example, a method for calibrating a position of a charge roller is described. The method may include a processor positioning a first end of a charge roller to a first plurality of index positions, determining a capacitance between the charge roller and a photoconductor imaging plate at each of the first plurality of index positions, determining a first index position of the first plurality of index positions with a greatest change in capacitance, and calibrating a position of the charge roller based upon the first index position.

Charge roller positioning

In one example, a device includes a flexible roller and an actuator to flex the roller while it is rotating to change the gap between the roller and a surface opposite the roller.
