Page 3: Circuit Description
UX-2200CMU/CMC FO-2150CMU/CMC [4] Circuit description 1. General description The compact design of printer PWB is obtained by using 8 bit microprocessor(CPU) and ASIC in the printer control section. 2. Electrical System The PWB provides mechanical control for Ink Jet Printer. Figure 1 shows the interconnection of PWB and other electrical component in the print mechanism. - Page 4 UX-2200CMU/CMC FO-2150CMU/CMC 3. Electricai Overview The information in this section appears in a sequence relative to the system diagram in the following figure. 8bit Host Interface TO FAX PWB 4. Power Supply Connector The mechanism requires two voltages (+5V and +24V). These two voltages supplied from CNPRT connector.
- Page 5 7. Driver IC The paper motor and carriage motor require current that cannot be driven directly from ASIC chip. 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.

- Page 7 UX-2200CMU/CMC FO-2150CMU/CMC 12. Home Position Sensor LEFT RIGHT 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).
