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.

SRAM 8bit MPU ASIC TO FAX PWB Host Interface Driver Head Driver Carriage Motor Driver Feed Motor Sensor •Home Position •Paper-IN Figure 2 System of printer Block diagram 4. Power Supply Connector The mechanism requires two voltages (+5V and +24V). These two voltages supplied from CNPRT connector. 5.
UX-2200CMU/CMC FO-2150CMU/CMC 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. Two additional drivers IC drive 56 nozzles on the cartridge.
UX-2200CMU/CMC FO-2150CMU/CMC (2) Print transfer The planetary gear turns clockwise and is disconnected from the PU gear,so that the paper is not fed automati cally. In case of hand paper feed the paper is fed directly to the transfer roller. HAND FEED PAPER PLANET GEAR MOTOR GEAR AUTOMATIC FEED PAPER PU GEAR When the mechanism stops, the automatic paper feed is not performed PRINTER FEED GEAR 9.
UX-2200CMU/CMC FO-2150CMU/CMC 12. 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.

UX-2200CMU/CMC FO-2150CMU/CMC [8] Service Checks 1. Carrier Transport Service Check 1 FRU Action System Board Check the motor for binds,or loose motor pulley. Turn the printer off and disconnect CN2 from the system board.Check for motor pins shorted to the motor housing.If you find a pin shorted to the housing,replace the motor. If the failure remains,replace the system board.
UX-2200CMU/CMC FO-2150CMU/CMC 2. Envelope Feed Service Check 1 FRU Action Envelope Guide Be sure the envelope guide has been turned to the envelope load position. Be sure the envelope guide is against the envelopes. Perform the ‘Paper Feed Service Check’on page 4. 3. Maintenance Station Service Check The maintenance station has two functions: • • Cleans the printhead nozzles during the print operation. Seals the printhead when it is not being used to prevent the nozzles from drying.
UX-2200CMU/CMC FO-2150CMU/CMC 4. Paper Feed Service Check If your machine does not have paper jam problems, continue with the service check. If your machine does have a paper jam problem,examine it for the following before you begin the service check: • • • • Check the entire paper path for obstructions. Be sure there is not too much paper in the sheet feeder. Be sure the correct type of paper is being used. Check for static in the paper.
UX-2200CMU/CMC FO-2150CMU/CMC 5. Paper Path Service Check Examine the machine for the following before you being this service check: • • • Check the entire paper path for obstructions Be sure the correct type of paper is being used. Be sure the printer is installed on a flat surface. FRU Action 1 Large and Small Feed Rollers Check for wear and binds. 2 Small Feed Roller Springs Check for damage. 3 Auto Sheet Feeder Check the pick rollers for wear.
