Page 20 (7) NHDC LSI(IC27: TC190G08CF-7036) This LSI controls timer, interruption, memories, printing, external interface, motor drive interface. (a) Timer control It controls the watchdog timer for detecting any out-of-control program, baud rate generator for setting the baud rate of the serial interface, and pulse generation timer for AG plus count.
Page 21: Initialization
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.
Page 22: Interface Control
2.1.4 Interface control The PM4410 is provided with the centronics parallel interface and RS-232C serial interface as standard features.Also, it can be connected to the optional Network I/F Card. The interface cable can be connected simultaneously with these interfaces. These interfaces can be switched with the menu switch on the operation panel, in addition, you can designate auto-select for them.
Page 23: Serial Interface
2.1.6 Serial Interface The MPU sets the baud rate which is selected with the menu switch for the NHDC LSI and have the serial I/F LSI to output the clock frequency of the baud rate. Input signals from the serial I/F (DSR, CTS, CD and RD) are converted into TTL level ones by the Line driver/receiver and input to the serial I/F LSI and NHDC LSI.

Page 32: Alarm Circuits
2.1.14 Alarm circuits (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 33 (6) Head thermistor short/open alarm circuit The head thermistor voltage is monitored physically. When short or open circuit occurs, the HDTHALM-N signal is input to the sub LSI (IC18) and read by the MPU. The MPU stops the printing operation, informs the host of the short/open alarm, and lights the alarm lamp. When the head is unloaded, the head thermistor becomes open, resulting in this alarm.

Page 35: Mechanical Operation
Mechanical Operation 2.2.1 Printhead mechanism and operation (See Figure 2-13) The printhead is a spring charged 18-pin (dual 9-pin) driving head using a permanent magnet. It is attached to the carriage, which moves in parallel with the platen. Electrically, this unit is connected to the control circuits through the control board.
Page 36 (2) Motion of Printhead (Fig.2-14) The armature usually looses the armature sprint with a permanent magnet, making it to be attracted by the core. In this time, the print wire integrated with the armature is also in reset state, When the magnet coil is energized by a print command sent from the device controller, a magnetic flux will generate in the opposite direction against that of the permanent magnet and a restoring force of the armature in the opposite direction against the core, and then the print wire impinge on the platen.
Page 37: Spacing Operation
2.2.2 Spacing operation (See Figure.2-15) Spacing is effected by driving the carriage assembly installed to the main shaft and slide beam set in parallel with the platen by the DC servo motor. (a) DC motor with motor (b) Carriage frame (c) Carriage shaft (d) Space belt (e) Sensor...
Page 38: Head Gap Adjusting
2.2.3 Head gap adjusting The auto gap adjusting mechanism automatically adjusts the space between the platen and print head according to the thickness of papers. This mechanism does this driving the platen back and forth with the AG motor (pulse motor), and effects the auto gap motion after the reverse motion of the platen.

Page 41: Ribbon Drive
2.2.4 Ribbon drive (See Figure) The ribbon feed mechanism feeds the ink ribbon and functions by driving the ribbon motor (pulse motor). (1) Ribbon cartridge This has a mechanism of capable of printing clear characters at all times by using a one-way- feed endless ribbon.
Page 42: Paper Feed Mechanism
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 43 (2) Rear tractor The rotation of the LF motor rotates 2 drive shafts through the LF gear, change gear and rear tractor drive gear A/B, driving the pin wheel and pin belt of the tractor Assy. This feeds a continuous paper set on the pin belt. Simultaneously, this drives the feed roller F/R through the mini-pitch belt following LF gear to carry the paper in synchronization with the tractor.
Page 44 (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.

Page 46: Bail Feed Mechanism
2.2.6 Bail Feed Mechanism (See Figure ) 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.
