In the drawing, there is shown a proposed system for implementing digital control over a copier scan servo. Referring thereto, an apertured timing disc 5 is attached to and rotatable with the copier photoreceptor (PR). The clock signals generated by a detector 6 on rotation of disc 5 are fed to a suitable frequency multiplier 7 which steps up the signal frequency, i.e., to 100 KHz. This permits control on a high resolution basis.
