Service Manual 2) Initial Reset Circuit IC6 (M51943BSL) is an IC to produce reset signals. When Vcc rises to about +4.25V or above with the power ON, The output of IC6 changes from “L” to “H”, RST of IC1 (CBM-606PC-**) is released from reset, and normal operation will start.
Service Manual 3. Printer Control Circuits 1) SOL1 to SOL9 are solenoid drive circuits of the printer. The transistor array of IC4 (HA13408) is driven by each signal, PA0 to PA7 and PB0, of IC1. This drives nine solenoids of the print head, files the print wire, and forms dot matrix characters through ribbon on the record paper.
Service Manual 4. Operation Panel Circuit This is composed of switches and LED. 1) Switches S1 (LF switch) and S2 (LINE switch) are provided. S1 is controlled by R18, C6, and IC7 (74LS04), and S2 by R17, C5, and IC7 (74LS04).
Service Manual 5. Drawer and Winder Control Circuit This circuit is composed of two circuits. AW (Winder) and DR1 are common for one circuit and each function is selectable. Another is the control for DR2 only. 1) AW / DR1 Control Circuit This is composed of R24, Tr4, tr5, and D1, and connected to PB6 of IC1 through IC8 to control AW and DR1.
Service Manual 6. Dip Switch Circuit 1) Dip Switch Circuit DS1 (Dip switch) is composed of eight switches, and reads with AN0 to AN7 of IC1. ONLINE / OFFLINE, character, CR control, AW / DR1 and so on can be set by setting of the Dip Switch.
Service Manual 7. Cutter Control Circuit (Option) This is composed of an input circuit to control cutter position and a drive circuit to operate the cutter. 1) Input Circuit The input circuit to control cutter position is input to PF2 of IC1 through R101, C101, and IC8 (74LS04) to control the cutter.
Service Manual 8. Serial Interface Circuit (3535R-type only) 1) Transmitting and Receiving Circuits (RS-232C) Data receiving (RD), BUSY (DTR), and FAULT signals are transmitted and received by a RS-232C transmitter of IC9 (MAX232C). RD signals are controlled by PC1 of IC1, FAULT signals by PC0 of IC!, and DTR signals by PC2 of IC1 respectively.
Service Manual 9. Parallel Interface Circuit (3535P-type only) 1) Input Signals to 3535P (a) D0-D7 These are circuits to input 8-bit parallel data signals from the host, and are input to PD0 to PD7 of IC1 through IC9 (74LS373).
