This document describes the features and characteristics of TDK programmable toner sensors, which are used in plain paper copiers and laser printers to maintain the correct mix ratio between toner and carrier.
This document provides technical specifications and application notes for the TDK TS series of Toner Density/Quantity Sensors. These sensors utilize a high-performance ferrite core differential transformer to monitor the mix ratio between toner and carrier in plain paper copiers and laser printers. The series includes models for one-sided (TS-A, TS-K) and double-sided (TS-L) substrates.

| Output filter time constant | 1max. |
They are developed to constantly maintain the correct mix ratio between toner and carrier in copiers and laser printers.
Yes, one sensor can accommodate the working point differences of each color toner with easily adjustable control voltage.
The detection sensitivity will drop when the quantity of developer around the sensor face is low (below 5mm).
