Manufactured by parent company Olivetti (who acquired AT&T in 1983) the AT&T 6310 compact electronic typewriter is a re-branded variant (I think) of the Olivetti CT-605 …

According to ribbon listings the following Olivetti-derived AT&T models were available:

AT-30, 5300 (Portable), 6100, 6110, 6200, 6210, 6300, 6310, 6400, 6500, 6510, 6610, 6710, 7500, 7500S, 7510, 7510S

I don’t own any of the above, however I do have an instruction guide for the 6310 which is shared here.

Given the size of the guide, I’ve split it into two PDFs and moved the sections that describe how to change the print wheel, ribbon cartridge and correction tape, from the Appendices into Part One.

Part Two comprises chapters on the SpellSure Dictionary, Memory and DataBank operation, How-tos on the design of stationary, resumes and charts, a Glossary, and an Index of Screen Symbols.

Non-essential pages to do with warranties and FCC regulations, etc have been omitted. Enjoy!
