Printronix P9000 Series manual Channel Assignment, End Load 6F Hex

Channel Assignment

The NVFU memory has the capacity for 256-line forms. The first line identification code (channel code) in the memory load program defines the first line on the form; the second line identification code defines the second line on the form, etc. Each line must have a line identifiF cation code. Filler channel codes are used for lines that will not be accessed by the print proF gram. The same filler channel code can be repeated as necessary for any number of lines. Table 5-7 illustrates the channel codes and load sequence.

Setting bit 5 of a channel assignment code will result in all channel assignment codes after this code being ignored until an end load code is received. The channel assignment code with bit 5 set is accepted as the last line of the form.

The top-of-form position is designated by channel 1. The first line of the form is automaticalF ly designated as a top-of-form. When the load sequence is received, the paper is assumed to be at the proper top-of-form position. After the memory is loaded, a Form Feed code (FF, 0C hex) will move the paper tothe next channel 1 (top-of-form).

End Load - 6F Hex

The end load code terminates the memory load program. The end load code is 6F hex with the PI line high.
