The MICROLINE (ML) 600 Series from OKI Printing Solutions: high-volume versatility in forms and correspondence.

Whether your output is continuous multi-part forms or fine business correspondence—or combinations of both—you’ll find your solution in the Dual 9-pin ML620/621 or the 24-pin ML690/691 dot matrix printers.

They handle the printing needs of the most demanding environments—including point-ofsale, automation and utility applications such as wholesale or retail sales counters, financial departments, manufacturing and warehousing.

Yet they also produce letter-quality type and high-resolution graphics for the office and executive suite.


Unequaled performance – ML600 Series printers have features that give them a strong edge over the competition:
• Print speeds of up to 700 cps1
• An MTBF rating of 25,000 hours
• Ribbon life of up to 13 million characters2


And they offer other features that will improve your working conditions, including:
• A convenient front paper path (tractor feed and friction feed)
• Printing on forms up to 7 parts3
• Versatile connectivity and paper handling


Fast, with finesse – ML600 Series printers run the gamut of paper types and envelopes at lightning speed. Their rugged printheads have a 400 million-character average life expectancy, with powerful samarium magnets and stored-energy pins that deliver precise, sharp characters through to the last page of a 7-part form3.
