7.4.7 ATR Control
0013-3721
imagePRESS C1 P / imagePRESS C1
The ATR control is executed to supply the toner to the developing assembly by calculating the supply amount from the toner consumption.
1. Description
a. Toner Supply Calculation
The amount of toner supplied to each developing assembly is determined.
This equipment calculates the necessary volume of toner supply based on data collected in three different ways.
- Video Count (counts each document output when printing)
Estimates the amount of toner consumption from video counts data, and thus calculates the amount actually consumed.
- Data from the Patch Image Scan Sensor (PS3) (performed sheet-to-sheet)
The patch image scan sensor measures toner image formed in the drum, and based on the data collected the amount of toner supply is adjusted so that the
over all density will get close to the target density.
- Data from the ATR Sensor (PS7) (detects every 8 document output of color print on A4 paper)
The ATR sensor detects the patch image density and the developer (toner and carrier) in the developing assembly cylinder of each color. If the results fall
outside of the target density range, toner supply target will be either increased or decreased.
