Our take
Xerox's detailed sheet distinguishes the WorkCentre 3655i/X from the 3655i/S. The X is a monochrome multifunction device rated up to 47 ppm on Letter, with print, copy, scan and fax functions, automatic duplex output, a 60-sheet duplex ADF and 700 sheets of standard input. It also includes an offline 20-sheet stapler, Gigabit Ethernet and a recommended average monthly print volume up to 15,000 pages. This is a substantial wired office device, not a small desk printer.
A wired office that needs mono fax, duplex originals and output, and the 3655i/X's workgroup paper handling..
Pass if you need color, a small footprint, built-in Wi-Fi, or a low-volume device without office-scale paper handling.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Xerox lists automatic duplex output and a 60-sheet duplex feeder for originals.
- Standard input totals 700 sheets and the X model includes a 20-sheet offline convenience stapler.
- The exact sheet states 47 ppm Letter speed and up to 15,000 recommended average monthly pages.
What to weigh up
- The X suffix must be verified because the S configuration does not include the same fax and stapler features.
- Wireless requires an optional USB adapter; standard connectivity is wired Ethernet and USB.
- The upper monthly recommendation does not establish the remaining service life of an older unit.

Full review: how the features affect your choice
What the features mean for you
Use the X suffix, not the family name alone
Xerox's configuration table lists both WorkCentre 3655i/S and WorkCentre 3655i/X. The X version includes walk-up fax and the offline convenience stapler; those should not be transferred to the S. The review and profile describe the exact 3655i/X only. Check the full suffix on the unit and verify its options and rating label, since marketplace titles often shorten a family name. The Xerox sheet supplies a baseline for original configuration, not proof that a seller's unit retains every component.
A mono workgroup document station
Xerox rates output up to 47 pages per minute on Letter and lists print, copy, scan and fax workflows. That combination fits a shared office where users need paper originals and faxing alongside routine black-and-white output. The printer does not offer color. A rated speed is not a guarantee for a large scanned job, complicated document or aged device, so compare it with the work pattern without treating the headline as a promise of real-world throughput.
Two-sided pages at both ends
The 3655i/X has automatic two-sided output and a 60-sheet duplex automatic document feeder. These are complementary features: one turns printed sheets, while the other captures two-sided originals. Xerox also lists simplex and duplex scan rates, and the feeder's supported sizes and paper weights are narrower than the bypass tray's media list. Check the original document mix and inspect both mechanisms on the offered unit. The specification capacity describes the design, not the condition of the rollers or duplex path today.
Standard capacity and finishing
Xerox lists a 550-sheet main tray plus a 150-sheet bypass, for 700 sheets of standard input. The X configuration also includes a single-position offline stapler that handles up to 20 sheets. These details matter in a shared room because they can reduce refill frequency and support a simple stapled handout without implying full inline finishing. Additional 550-sheet feeders are optional. Confirm what is physically included and plan space for the printer, trays and output before bringing this large device into the office.
Wired networking with optional wireless
The detailed sheet lists 10/100/1000Base-T Ethernet and high-speed USB as standard. Wi-Fi Direct requires an optional Xerox USB wireless adapter. Profile the exact standard model as wired and do not assume the accessory is present just because a seller calls the printer wireless-ready. For a managed office, confirm network authentication, address assignment, print drivers and scan destinations. A successful model specification does not establish that a used Ethernet port, touchscreen or optional adapter works on a particular unit.
Compare the range with service and space
Xerox recommends an average monthly print volume up to 15,000 pages. The source does not provide a lower endpoint, so only the upper recommendation is recorded. Do not substitute the separate 150,000-page duty cycle as a recommended target. This machine is heavy and offers high paper capacity; weigh that footprint and service burden against actual office demand. Request a test page, scan and fax demonstration, tray count, stapler, drum and toner state, and return terms. No current price or offer condition is asserted.
Compare for your needs
For a smaller setup compare a mono fax MFP with a lower documented range; for built-in wireless, select a model whose exact standard configuration includes Wi-Fi.
