Motor driver IC provide the additional current and voltage capability. The driver IC (IC1 and IC2) located near the respective motor connector on the printer PWB also connect back to the ASIC. Two additional drivers IC drive 56 nozzles on the cartridge. These driver ICs , located between the two flex-circuit connector (CN3 and CN4) on the printer PWB , also

Home Position Sensor LEFT RIGHT B C A CARRIAGE HOLDER The home position of carriage is detected as a result of change of output of photointurrupter A which is caused due to shutting-off of optical path of photointerrupter A by the slit B . While the photointerrupter is shut off by the slit B, the output (pin 1 of CN3) of photointerrupter gets H level (+5V). If it is not shut off, the output gets L level (0V). In the home position the output is L. In case
