ABSTRACT:
A circuit and a method of estimating pulse frequencies of nozzles in an ink-jet head use a new mechanism of estimating pulse frequencies of nozzles instead of in a conventional counting mechanism. The circuit includes a DRAM, an adder and a method control mechanism. The method control mechanism controls the access method. The DRAM retrieves a plurality of pulse frequency parameters of nozzles after ink-jet cycle signals are received. The adder adds the parameters and weighted values to update pulse frequency parameters. The updated parameters are saved back to the DRAM.
