Title: Toner concentration control method for image forming device
Inventor: SAWAI YUJI
IPC: G03G15/08
Filed: 1988-03-16
Abstract: PURPOSE:To appropriately evade an excessive state of a toner replenishment and to surely prevent ground contamination and toner scattering by maximizing the toner replenishment rate and setting a reference pattern detection mode shorter than usual, when an output of an image density sensor exceeds a control reference value. CONSTITUTION:After a main switch of an image forming device is turned ON, a reference pattern detection mode is executed once each per an exposure of 10 times, and a toner replenishment control by an image density sensor is executed. In such a case, when a sensor output VSP exceeds a second control reference value K2, it is under the toner concentration which can obtain correct density, therefore, the replenishing operation is executed by raising the toner replenishment rate to a state corresponding to 60% the maximum black solid part area rate. In such a case, after the toner replenishing operation is executed five times, the next reference pattern detection mode is executed, and the detection interval is shortened. In such a way, an excessive state of the toner replenishment is evaded appropriately, and ground contamination and toner scattering can be prevented surely.

Filed: 1987-03-17
Abstract: PURPOSE:To integrate the constitution of respective control units and to effectively obtain the synchronization of the entirety of a system by connecting the detecting signal output part of a timing detecting circuit to the input part of the operating clock of the control unit of a lower order side by one step than the control unit thereof. CONSTITUTION:When bucket data is transmitted from the high order control unit 2a, the transmitting timing is detected in the timing detecting circuit 10 and a timing detecting signal is outputted. This timing detecting signal is inputted to the control unit 2b of the lower order by one step as the operating clock. Accordingly, since the lower order control unit executes a data transmission operation to the transmitting timing of the control unit of the higher order, the higher and lower control units are mutually synchronized. Thereby, the higher order control unit can effectively fetch the transmission data from the lower order control unit and a proper circuit is not required for every hierarchy, so that the control units are integrated.
