Teletype 2101AB Inktronic Printer - AN/UGR-14

• Back to Main Navy Teletype Page
• Please send me email with any info, manuals, etc. I only have some docs for the earlier 2101AA  model
• More photos coming later as I start getting into the machine

I need manuals and wiring diagrams for the 2101AB version of the Inktronic. Please send me email if you have any to copy/borrow/rent/buy.
The manuals I need are BSP No. 578-500-101, 578-500-113, 578-500-114, 578-500-115, 578-500-201, 578-500-301, 578-500-704, 578-500-705, and Wiring Diagram Package WDP 0256.

Note - the earlier documents call this the "INKTRONIC" printer and the later ones call it the "DATASPEED" printer.

Ink specification. Paper specification.

How does it work? Electrostatic control of a stream of ink droplets. Maximum printing rate is 120 characters/second (1200wpm) A nozzle charged to -1900v produces a stream of ink droplets that are pulled toward the paper by a +10,000v charge on the platen. Undesired droplets are blocked by a +500v gating electrode. Desired droplets are steered up/down & left/right by deflection electrodes. Droplets impact the paper to create 8x10 dot characters (8x14 in the ASCII version). There are 40 nozzles across a line, each of which is responsible for writing 2 characters. Nozzles are energized sequentially. For more info see this manual and this one
