Abstract
In one example, a method is described that includes a processor detecting a voltage of a photoconductor layer (103) of a printing device, comparing the voltage of the photoconductor layer (103) to a threshold voltage, and applying a corrective voltage to a charging unit (110) or to a transfer member (104) when the voltage of the photoconductor layer (103) exceeds the threshold voltage.

A method, comprising:
- detecting a voltage of a photoconductor layer of a printing device, wherein the voltage is detected between an erase operation and a charging operation;
- comparing the voltage of the photoconductor layer to a threshold voltage;
- and
- applying a corrective voltage to a charging unit when the voltage of the photoconductor layer exceeds the threshold voltage.
