In CARPS, the following takes place so as to generate output as fast and as easily as possible:- Instead of converting the print data coming from the application into the printer's page description language (PDL), it turns it into resource data which is GDI-IC FunctionIC1 CPU (ASIC)DRAM controller, image processing block, USB controller, LAN controller, reader unit controlIC2 FLASH ROMprogram control, data retentionIC3 FLASH ROMprogram control, data retentionIC301 LAN controlIC501 DDR memoryIC502 DDR memoryIC601 ADF motor driverIC651 book mode motor driverIC701 control panel controllerIC801 fax modemIC1001 image processing controllerIC1002 flash ROM for image processing data storageIC1101 ASIC for recording signal controlIC1201 clock IC communication block, recording signal processing block, image signal processing blockJackÅ@No. FunctionJLBP1 DCNT board connectorJUSB1 USB terminalJLAN1 LAN cable terminalJETM1 not usedJBAT1 capacitor terminalJPSU1 power board connectionJFAN1 fan connectionJAMTR1 CCD motor connectionJBMTR1 ADF, motor connectionJSPK1 speaker connectionJSNS1 power sensor/post-separation sensorJOP701 control panel connectionJOP702 control panel connectionJNCU1 NCU board connectionIC1101IC801IC1001IC1002JUSB1USB CCDLANJLAN1JETM1JBAT1IC1201IC2IC3JLBP1CCDDCNTBoradIC301IC502IC601JAMTR1JFAN1FAN BookMotor ADFMotor SpeakerSuperC UnitJBMTR1 JSPK1 JSNS1JNCU1JPSU1NCU BoradIC651 IC701 JNCU2IC501 IC1Sensor control panel controllerNCU BoradBATTERYJOP701JOP702+24V+3.3V+5V+13.5V
