    2.1.3 Initialization This printer is initialized when the power is tumed 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

    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 option OKI HSP or Opt. 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.

This protective circuite 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 35: Mechanical Operation

    Mechanical Operation 2.2.1 Printhead mechanism and operation (See Figure 2-13) Teh printhead is a spring charged 18-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 (See Figure.2-15)

  • 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.

  • 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 hte 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.

    (4) Stored historical page number data This function counts a page each 11inch and stores it to EEPROM. The storage capacity for the counter is 3byte, which equals to pages for 70 years at 20000 pages/ month. As the printer has no function which is capable of resetting this counter, line feed frequency can be known since the printer's shipment.

This manual is also suitable for:

Microline 4410
