BR-C1 Training What is Process Control? Background In the electrostatic copying process, many conditions such as changes in temperature, length of time the machine has remained idle, print mode selection (amount of toner on a page), etc., affect image quality. The machine must frequently sample the machine's development ability (condition or status) at prescribed intervals, and then make adjustments based on these...
Page 287
BR-C1 Training What is Process Control? Process control can be divided into two separate phases: 1. Potential control. Performs adjustments for development that affect basic image quality such as gradation levels, line width. 2. Toner supply control. Standardizes the image density by controlling toner supply. These two methods have been already adopted the color products.

BR-C1 Training Toner Supply Control Overview Two methods of toner supply are used with this machine. Fixed supply PID control SP3400-001 determines which method is used "0" (Fixed Supply) or "1 (PID). With the “PID” setting, the machine makes a pattern on the ITB at set intervals (see the next slide) and reads it with the ID sensor.
Page 297
BR-C1 Training Toner Supply Control Pattern Toner supply control is performed by projecting a pattern onto the ITB during the intervals between sheets of paper during printing. Default: 1 pattern per 20 A4 LEF sheets. The ID sensor reads the reflectivity of the pattern (affected by how much toner is present), and then the machine uses the reading to adjust toner supply.
