  • Page 29: Line Matrix Printing

    Line Matrix Printing The 9212 creates characters and graphics by a printing technique called line matrix printing. Line matrix printing consists of printing patterns of ink dots on paper, an entire line at a time. Each text character is stored in memory as a pattern of dots on a logical grid called the dot matrix.

  • Page 31: The Hammer Bank

    The Hammer Bank The P9212 uses a hammer bank to print dots. The hammer bank consists of 88 hammer springs mounted on a shuttle that moves horizontally a short distance back and forth. The hammer bank prints one horizontal line of dots during each horizontal sweep of the shuttle.

  • Page 34: Normal Operation

    Normal Operation In normal operation, the user presses a switch on the control panel to put the printer on–line. Data from the host computer are then read into the input buffer as ASCII data. (Printers with CT or CTHI options for twinax/coax/IPDS operation convert IBM EBCDIC code to ASCII before processing the data.) The data in the input buffer are compared to tables stored in memory to determine the matrix and location of each character.

  • Page 36: P9212 Architectures

    P9212 Architectures The physical configuration of the P9212 is determined by the type of processor board and interface it uses. Printers that use the Common Controller Board (CCB) are PROM–based machines. Printers that use the LMI print engine are floppy–based machines. CT and CTHI models use translation interfaces that enable them to emulate IBM printers.

    Controller Boards The printer is controlled by either the Common Controller Board (CCB) or the Line Matrix Impact (LMI) print engine. These boards control the printer in very similar ways. The main difference between them is the way operating system and font information is stored: the CCB gets this information from PROMs, the LMI loads the information into RAM from floppy disk.

  • Page 44: Controller Communication With The Host And Operator

    Controller Communication With the Host Computer and Operator The controller board processes three kinds of computer input: Centronics parallel, DataProducts parallel, and RS–232 serial data. The RTPU operates all three interfaces. The parallel interfaces are similar, and the RTPU contains direct–memory–access (DMA) hardware which loads parallel data directly into shared memory.

  • Page 45: Hammer Driver Interface Functions

    Hammer Driver Interface Functions In order to print a dot image, two things must happen. First, the dots must get to the hammers one dot row at a time and in the correct sequence. Second, the hammers must be fired at the appropriate time in the stroke of the shuttle. The RTPU microprocessor controls both of these functions, but each is actually performed by an application–specific integrated circuit (ASIC) containing hardware dedicated to the function.

  • Page 46: Mechanical Interface Functions

    are all considered by the RTPU processor as it programs the dot plucker and the FTIC for each dot row. Transfer of dots to the Synchronizing Dot Plucking and Hammer Firing hammer driver must be synchronized with hammer firing. Dots are transferred to the hammer driver in bursts, serial streams of dots that tell which hammers will print when their phase is next fired.

  • Page 47: Fault Monitoring

    The DPU determines when paper must be moved and how far Paper Motion to move it. It communicates this to the RTPU through the shared memory. The RTPU processor performs some paper handling operations (such as holdback on slews), but most RTPU paper handling is done by a dedicated microcontroller called the paper feed controller (PFC).

  • Page 48: Ccb Hardware Summary

    CCB Hardware Summary This section summarizes CCB hardware functions. (LMI hardware is summarized on page 2–26.) A Motorola 68010 microprocessor performs the DPU functions, a 64180 microprocessor handles the RTPU functions, and an 8032 microcontroller serves as the paper feed controller (PFC), which is part of the RTPU. Actual implementation of this hardware blurs the distinctions between the DPU and RTPU, since the 68010 has access to the parallel port and the real–time functions of the dot plucker, which are RTPU resources, while the 64180 has...

  • Page 50: Communicating With The Host Computer

    Communicating With the Host Computer The 64180 processor runs both the parallel and serial interfaces. Parallel input data is nine bits wide, and is transferred in one Parallel Input cycle from the parallel port to shared memory over the shared sixteen bit bus. Using the internal DMA controller of the 64180 to transfer parallel data requires some manipulation.

    results in immediate movement. Other paper commands and status signals are also passed through this port. The 64180 interfaces through its second UART Ribbon and Shuttle Motion to the ribbon / shuttle processor (RSP) on the mechanism driver board. The 64180 begins all transactions on the serial interface.

Other paper commands and status signals are also passed between processors through this port.

    Mechanism Driver Board The mechanism driver board, acting on timing and control signals from the CCB or LMI, controls real–time operation of the electromechanical printer systems.

  • Page 59: Ribbon Drive System

    Ribbon Drive System The ribbon drive system is controlled by the 8032 microcontroller. The controller board sends commands to the 8032 to start and stop the ribbon, set the ribbon speed, and apply slack or tension to the ribbon. The real–time control functions are done by the 8032, acting in accordance with firmware control algorithms and look–up tables.

  • Page 60: Start / Stop Ribbon

    Start / Stop Ribbon The ribbon motors are started and stopped by a digital signal from the controller board. After a stop signal is received, the ribbon is locked to maintain tension. If the controller board sends a slack signal, the PWM amplifiers are tri–stated.

    Hammer Driver Board The hammer driver board consists of three functional elements: hammer driver logic and control circuits, blower drive and monitoring circuits, and filter capacitors for the +48 V and +12.5 V power supplies.

  • Page 63: Hammer Bank Cooling

    Hammer Bank Cooling The hammer driver board also powers a blower that cools the hammer bank. A fixed 60/40 signal (PWM) is provided to the hammer driver board to run the blower. The hammer driver board demodulates this signal to a binary logic (on/off) signal, then drives a MOSFET that powers the blower.

  • Page 64: Power Supply

    Power Supply The power supply board, ac input connector, power switch/circuit breaker, and a cooling fan are contained in a removable steel module at the rear of the printer. The power supply senses and adjusts to any commercial electrical system that provides ac mains potential in 50 or 60 Hertz systems. AC input power is converted to +48 volt and +12.5 volt dc power and sent to the hammer driver board for filtering.

  • Page 65: Print Mechanisms

    Print Mechanisms Hammer Bank, Shuttle, and MPU Printing is synchronized with shuttle movement by signals from the magnetic pickup unit (MPU). The MPU, located next to the flywheel timing disk, is so oriented that timing signals relate precisely to the shuttle position. Variations in magnetic reluctance are sensed by the MPU from apertures on the timing disk as it rotates, generating SYNC pulses.

  • Page 67: Ribbon Deck

    Ribbon Deck The printer ribbon winds and unwinds continuously on a pair of spools latched to hubs driven by the ribbon motors. The ribbon motors operate only while the hammer bank assembly is running. Ribbon motion reverses when the metal strip at either end of the ribbon crosses the left or right ribbon guide, completing a circuit that causes both motors to reverse direction.

  • Page 68: Paper Feed Control

    Paper Feed Control The paper transport system accepts continuous, fan–folded, edge–perforated paper from three to 16 inches wide and from one to six sheets thick. Horizontal positioning is provided by the horizontal adjustment knob and two tractors. The tractors are laterally adjustable along the splined and support shafts.

  • Page 287: Print Rates

    Print Rates The printing speed of text characters is a function of the selected font and dot density, and is measured in lines per minute (LPM). Print speed is independent of the number of characters configured in the character set. Text attributes such as bold or emphasized printing, superscripts, subscripts, or elongated characters cause print rates to decrease to not less than half the rates of the font without such attributes.
