Auto duplex units add automatic two-sided printing to a printer that does not have it built in: add-on hardware that flips a page mid-print pass so a printer can produce double-sided output without a user manually reinserting each sheet. Where paper cost or volume makes double-sided printing worthwhile, a duplex unit is what automates it on a printer that otherwise only prints single-sided.
Duplex units are printer-model-specific - order by the exact printer, since installation and paper-handling mechanics are matched to a particular model's paper path. Confirm the printer's expansion bay or connection point supports the duplex unit before ordering, since not every printer in a given line has the same expansion option. For high-volume printing environments, an auto duplex unit reduces both paper cost and the manual handling time a two-sided job otherwise requires. COLAMCO supplies auto duplex units for the printer fleets business, government, and education organizations run.
