Page 18: Microprocessor And The Peripheral Circuit
Page: 8 Service Guide for PM4410 Chapter 2 Operation 2.1.2 Microprocessor and the peripheral circuit (1) Microprocessor (IC24: 80C186-16) This processor is a CMOS single-chip computer with integrated peripheral device functions and a 16 bit MPU core. The processor has a 20 bit address bus and a 16 bit data bus. It is capable of accessing up to 4M bit program memory and 4M bit of data memory.
Page 19 (2) PG ROM (IC46) This is a 256 x16 bits (4M bit) EPROM with the control program for the printer stored. The MPU executes instructions under this program. The program ROM is assigned to the program memory area of the MPU and is fetched by the RD signal of the MPU. The following shows the operation of the memory access.
Page 20 (3) DRAM(IC28) The RAM is CMOS dynamic RAM with (256K x 16 bit) configuration, and used as buffers (such as receiving buffer, printing buffer, DLL buffer and working buffer). The following shows the examples of the memory access operation.
Page 21 (4) CG ROM (IC48) This is a 256K x 16 bits (4M bits) EPROM with the font data for the characters stored. CG ROM is assigned to the program memory area of the MPU and is fetched by the RD signal of the MPU. The following shows the memory access operation.
Page 22 (5) EEPROM(IC40) The EEPROM is a CMOS serial I/O type memory which is capable of electrically erasing and writing 1,024 bits. The EEPROM contains menu data. The following shows the memory access operation.
Page 23 (6) Main LSI (IC38: MSM91U036) MSM91U036 is control LSI for head data, DC motor and modification of print data, which has the following functions. (a) Head data control It distributes print data stored in the DRAM over wire arrangements of the print head and outputs it as dot data in synchronism with print timing.
Page 24 (d) I/O port This printer has 8-bit output port which is used for controlling the SRAM. (e) Head position count It counts the outputs from slit sensors (SPPHASE A, B) located on the space motor to keep monitoring the current position of the print head.
Page 25 This LSI is the serial I/F LSI which controls the input/output of serial I/F controlling signals with command inputs from the MPU. Copyright 1998, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material. (http://bpx.okidata.com)
Page 26: Initialization
Page: 9 Service Guide for PM4410 Chapter 2 Operation 2.1.3 Initialization 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. For the initialize operation, the RESET-N signal is first output from the reset circuit to reset the MPU and LSIs. When resetting ends, the program starts and the LSIs are reset by NHDC LSI via LRESET-N.
Page 28: Interface Control
The selected interface is stored to the EEPROM and can maintain even after powering the printer off. Copyright 1998, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material. (http://bpx.okidata.com)
Page 29: Parallel Interface Control
When reception is impossible because the buffer is full, the BUSY signal is sent to request stopping of data transmission. Copyright 1998, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material. (http://bpx.okidata.com)

Page 31: Printing Operation
During the line feed operation, the MPU causes the carriage to decelerate. Upon termination of line feed operation, the spacing operation is performed. Copyright 1998, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material. (http://bpx.okidata.com)
Page 32: Printhead Control
Page: 14 Service Guide for PM4410 Chapter 2 Operation 2.1.8 Printhead control The printhead is controlled by the Main LSI and NHDC LSI. Printing is synchronized with the ITOUT signal from the NHDC LSI. The NHDC LSI outputs the dot timing1 signals (DT1:1~18) and the dot timing2 signals (DT2:1~18), and the driver IC drives each dot magnet.
Page 34: Print Compensation Control
According to the thickness of the printing medium, the print mode is compensated as shown in the table below: Copyright 1998, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material. (http://bpx.okidata.com)
Page 35: Space Motor Control
Page: 16 Service Guide for PM4410 Chapter 2 Operation 2.1.10 Space motor control (1) The Main LSI generates the SPDV-P signal upon receiving the spacing command from the MPU. This is a fixed cycle pulse signal. The Main LSI varies the pulse duty according to the speed data from the MPU to control the motor speed. The SPFOW-P or SPREV-P signal from the Main LSI changes the current direction in the DC motor to run the motor in the forward or reverse direction.
Page 37: Line Feed
It is driven by +44V application by the LFOVDV-P signal for line feed operation. Copyright 1998, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material. (http://bpx.okidata.com)
Page 38: Bail, Tractor, Switching, Ag, Ribbon Motor Control
Bail, tractor switching, AG and ribbon motor control is as shown below. The AG motor is locked with AGHOLD-P. Copyright 1998, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material. (http://bpx.okidata.com)
Page 39: Operation Panel
Page: 19 Service Guide for PM4410 Chapter 2 Operation 2.1.13 Operation Panel The clock synchronization OPCLK of NHDC LSI is used to input the switch data and output the LED data and LCD data through the operation panel control LSI (IC1: BU6152S). A 2-byte (15 bits + 1 even parity bit) command (OPDATAOUT-P) is transmitted to the LSI (BU6152S) in synchronization with the OPSCLK-N signal.
Page 40 This is because the bit 0 to bit 3 of OPDATAIN-P are fixed so that the response can be returned before decoding the command. Copyright 1998, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material. (http://bpx.okidata.com)
Page 41: Alarm Circuit
Page: 20 Service Guide for PM4410 Chapter 2 Operation 2.1.14 Alarm circuit (1) Driver circuit abnormality detection alarm. This protective circuit prevents secondary troubles by stopping the power supply upon detection of an abnormality in the print head, SP motor driver circuit or other motor driver circuits. This circuit monitors the driving time by means of the signals (DT1COM1, SPV, LF COM, AG-MCOM, RBN-MCOM, TR-MCOM, BEIL-MCOM and RENCOM) connected to the overdrive signals for each driver circuit.
Page 42 With no rotation for 16 sec. or longer, the MPU stops the printing operation, informs the host of the ribbon jam, and lights the alarm lamp.

Page 55: Paper Feed Mechanism
Page: 27 Service Guide for PM4410 Chapter 2 Operation 2.2.5 Paper Feed Mechanism The line feed on the print paper is driven by the LF motor (pulse motor) and done by rotating the sheet feeder and feed roller. (1) Front tractor The rotation of the LF motor rotates the drive shaft through the LF gear, change gear and front tractor drive gear, driving the pin belt of the front tractor Assy.
Page 56 (3) Tractor changing motion The front tractor and rear tractor are switched by exclusive tractor change motor (pulse motor). Operating keys on the operating panel and receiving a command rotates the tractor change motor, moving the tractor change lever back and forth through gears so that the change gear moves transversely. If the change gear is shifted to right, the rotational force is transmitted to the front tractor gear, driving the front tractor.

Page 59: Bail Feed Mechanism
Page: 28 Service Guide for PM4410 Chapter 2 Operation 2.2.6 Bail Feed Mechanism This mechanism automatically opens the bail for pulling a paper into, and closes it after the paper passes through the bail. This function is operated by exclusive bail motor (pulse motor). The bail motor rotates depending on the position of a paper, moving the bail lift lever (L) back and forth through gears.
