The Model 300/600 MICR Printer
I. GENERAL INFORMATION
The throughput of the printers are rated up to 600 documents per minute. The
print format is 8 characters per inch and 120 columns per line. Line density is
either six or eight lines per inch. Print drums with either E13B or CMC7 MICR
(Magnetic Ink Character Recognition) font are available. Special total-
transfer ribbons with ferrous particles mixed in the ink are used to generate the
characters.
The printer is connected to either a Centronics, Dataproducts or Serial interface.
ASCII or Dataproducts character codes can be used for character selection. Print
images are transmitted a line at a time, and stored in a non-volatile memory on the
Microprocessor board. Timing marks on the drum are used to generate image
scans which the Microprocessor uses to match characters from the print image.
Vertical format is maintained with control codes which follow every line of data.
These codes determine if the printer will advance paper from zero to 15 lines or
the remainder of the form after printing the current image. Multiple line movement
is processed by a vertical format unit which monitors paper positioning and vertical
tab (channel) stops. Paper is transported by four pin-feed tractors under the
control of a closed loop servo system.
