  • Page 13: Maintenance Overview

    Maintenance Overview About The Printer The entire system architecture of an IBM* 6400 line matrix printer is contained on one circuit board. The use of DRAM and flash memory on this board permits rapid access to stored printer emulations and fast processing of print data.

  • Page 29: Preventive Maintenance

    Preventive Maintenance Cleaning The Printer Aside from normal replenishment of paper and ribbons, the only preventive maintenance required for the printer is periodic cleaning. Because operating conditions vary widely, the user must determine how often to clean the printer. There is no guarantee that the user will clean the printer regularly, however, so you should clean the printer whenever you are called to service it.

  • Page 35: Principles Of Operation

    Principles Of Operation Line Matrix Printing The printer creates characters and graphics by printing patterns of ink dots on paper, an entire line at a time. This technique is called line matrix printing. Every text character is stored in printer memory as a pattern of dots on a logical grid called the dot matrix.
  • Page 36 Chapter Line Matrix Printing When the shuttle reaches the end of a sweep, it reverses direction, the paper is advanced one dot row, and the hammers print the next row of dots as the shuttle sweeps in the opposite direction. After a line of characters is printed, hammer action stops and the paper advances to the first dot row of the next print line.

  • Page 38: Printing Rates

    Chapter Printing Rates Printing Rates Because a line matrix printer prints entire lines sequentially, it is faster than a moving-printhead printer, which prints single characters sequentially. The printing speed of text is measured in lines per minute (lpm) rather than characters per minute (cpm).
