1 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. A variable-speed shuttle and half-step paper control enables the printer to print a wide variety of high-volume jobs with minimum maintenance and maximum reliability. Although technologically advanced, the printer is easy to use. The operator can select every printer function at the control panel or by sending printer control codes in the data stream from the host computer. This is also an excellent graphics printer, with optional features that simplify the creation of dot images. The IGP** and Code V** Printronix** emulations are simple but versatile graphics programming languages that load into flash memory. The IBM 6400 Series Printer Family The IBM 6400 Line Matrix Printer family consists of pedestal mount and floor cabinet models that print at different speeds, as shown in Table 1. The print speeds listed in Table 1 are the maximum speeds attainable under certain conditions. Actual print speed is determined by the interaction of many variables. For more information, refer to the discussion of Printing Rates in Appendix B, page 342. Maintenance Overview 13
