Our take
The WorkCentre 3345/DNI combines monochrome print, copy, scan, and fax. Xerox rates it up to 42 ppm Letter and 21 ppm duplex, with a 50-sheet reversing ADF, USB, Gigabit Ethernet, and Wi-Fi. Its standard paper input totals 300 sheets, and recommended average monthly volume is up to 6,000 pages.
A wired or wireless office needing fax and two-sided handling for both output and scanned originals..
Skip it if you need color output or if a two-ended recommended monthly range is essential to your choice.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Automatic duplex is documented for print output, and a reversing ADF supports two-sided originals.
- Fax, copy, scan, Wi-Fi, and Ethernet are included in the model family.
- Xerox publishes a maximum recommended average monthly volume of 6,000 pages.
What to weigh up
- The monthly volume source gives an upper recommendation without a lower endpoint.
- The 3345 is an older model, and the specific unit's condition and software fit are unknown.
- Optional trays are not standard; the standard input is 300 sheets.

What the features mean for you
A mono MFP for shared paper tasks
Xerox describes the WorkCentre 3345 as a monochrome multifunction printer with print, copy, scan, and fax functions. The DNI configuration is a U.S. networked model, and the manufacturer's family specification covers the 3345 feature set. This makes it suitable for a small office that handles paper originals as well as everyday print jobs. The black-only output is a real boundary: choose a color device when charts, marked-up pages, or handouts need color. Confirm the exact /DNI suffix and U.S. product label on the unit rather than assuming every WorkCentre 3345 listing has the same ports and accessories.
Speed and volume guide a different kind of decision
Xerox rates the 3345 at up to 42 pages per minute Letter, 40 ppm A4, and 21 ppm Letter duplex. Its recommended average monthly print volume is up to 6,000 pages, with no lower endpoint in the reviewed data. These are separate measures: rated speed does not establish a lower workload fit, and the maximum duty-cycle value is not a monthly recommendation. Use the upper recommendation as a ceiling signal, while treating lower-volume guidance as unknown. A team can compare its routine against these values without turning them into a guarantee for every page or used machine.
Automatic duplex includes originals as well as output
The 3345 supports automatic two-sided printing and has a 50-sheet reversing automatic document feeder. The print feature turns outgoing sheets; the reversing feeder processes both sides of originals for scan, copy, and fax routines. That can be valuable in an office where paper arrives in packets instead of single sheets. Xerox's source also describes the feeder's supported document sizes and weights, so unusually thick cards or fragile originals should not be fed without checking those limits. Test duplex output and feeder reversal on the exact unit before relying on it for a recurring workflow.
Wireless and Ethernet allow flexible placement
The WorkCentre 3345 specifications list USB 2.0, 10/100/1000Base-T Ethernet, and Wi-Fi. This gives an office both wired and wireless paths, rather than requiring an optional Wi-Fi card for the standard configuration. Xerox also documents a 250-sheet tray, 50-sheet bypass, and standard capacity of 300 sheets; the 550-sheet additional tray is optional. That distinction matters when comparing seller bundles. Confirm wireless setup, security compatibility, installed tray count, and driver support on the machine. Network capabilities in the manual do not prove a specific used device has working radios or a configured connection.
Older office hardware needs an exact-unit check
The saved Xerox user guide and specifications establish the designed WorkCentre 3345 workflow, but they do not describe the condition of an individual device. Check the /DNI nameplate, power cord, duplex path, reversing feeder, fax interface, Wi-Fi and Ethernet, toner and maintenance history, and optional tray hardware. Xerox's system sheet lists an up-to-6,000-page recommendation, not current supplies or a promise of remaining life. Also verify computer drivers and scan destinations in the intended network. If the unit cannot be tested, treat its working condition as unresolved even when the model itself is well documented.
What else to compare
Compare a smaller mono MFP if the 300-sheet standard input and 6,000-page upper guidance exceed the office routine.
Before you buy
Does the 3345/DNI fax?
Yes. Xerox's 3335/3345 specification includes fax functions for the 3345.
What is the recommended monthly volume?
Xerox states up to 6,000 pages on average per month; it does not give a lower endpoint.
Is duplex scanning confirmed?
Xerox lists a 50-sheet reversing ADF for the 3345, distinct from its automatic duplex print feature.
