%2.1.04 Print Control2.1.04 Print ControlThe print data is transmitted as serial data from the LSI to the control circuit and the driver contained inthe printhead.After the data is printed, the sensor analog circuit controlling each pin returns the pin stroke data to theMPU. The MPU will make an automatic head gap adjustment. This feedback system sets the optimumdrive time for each pin in order to maintain high print quality.In the case of envelopes, where the medium thickness varies as the printhead moves along the platen,the strike force of the pins changes to compensate for the differences in thickness.ML520/521 ( 96-02-04 )
