(2) Alarm processing when DC power is low.

This cause the secondary coil (40V) of the transformer to be short-circuited, causing an overcurrent to flow through the primary coil and making the AC fuse (transformer assy) open. If the drive time of any drive circuit exceeds the specified time, the drive fault alarm circuit sends an ALARM-N signal to turn on the SCR (SO). This circuit monitors the drive time using the HDALM signal interlocked with the overdrive signal of each drive circuit. The program here sets the mode of the LSI including the MPU, checks the memories (ROMs and RAMs), then carries out carriage homing, and determines the LF motor phase.įinally, the program establishes the interface signals (P-I/F: ACK-P signal sending, and S-I/F: BUSY-N signal off) and lights the SELECT lamp to inform the ready state for receiving to the host side and ends the initialize operation. Reset operation by I-PRIME starts program to initialize, but does not reset the MPU. When resetting ends, the program starts and the LSIs are reset by MPU via LSIRST-N. This printer is initialized when the power is turned on or when the I-PRIME-N signal is input from the host side via the parallel interface.įor the initialize operation, the RST-N signal is first output from the reset circuit to reset the MPUs and LSIs.

The function of this microprocessor is to provide a central mechanism for the entire printer by executing the control program through the LSI and driver circuits.

8-bit parallel port × 3 (bitwise I/O specification available).

The following characteristics are also provided: It is capable of accessing up to 1M word program memory and 1M bytes of data memory. The processor has a 20 bit address bus and a 16 bit data bus. This processor is a CMOS single-chip computer with integrated peripheral device functions and a 16 bit MPU core, all OKI original architecture. The power to other electrical parts is also distributed through the connectors within the control board.Ģ.1.2 Microprocessor and the Peripheral Circuit The power to the control board is supplied by the power board through the connector cord. The control board is made up of the microprocessors, peripheral circuits, drive circuits, sensors and interface connectors. 2-1 shows the block diagram of the printer.
