Our take
Lexmark's U.S. page identifies the MC3426i as part 40N9650 and describes a color laser all-in-one for printing, copying, and scanning. It adds automatic print duplex and a 50-sheet automatic document feeder that scans both sides in one pass, plus standard Wi-Fi and Gigabit Ethernet. Lexmark rates Letter printing up to 26 pages per minute and recommends 750 to 5,000 pages per month. Fax is optional cloud service; Lexmark says analog phone-line fax is not supported. That distinction matters before treating it as a general fax MFP.
A shared color MFP for copy, scan, and two-sided document handling when cloud fax, if needed, meets the user's fax workflow..
Choose another model if analog fax is required, if a print-only device is enough, or if you need a non-discontinued product line.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Print, copy, and color scan are documented for the exact U.S. MC3426i configuration.
- Automatic print duplex and a 50-sheet single-pass duplex ADF handle two-sided output and input.
- Standard Wi-Fi and Gigabit Ethernet give a shared office wired and wireless connection options.
What to weigh up
- Fax requires an optional etherFAX cloud subscription; analog phone-line fax is not supported.
- The recommended 750–5,000-page range is a manufacturer guideline, not a guarantee of a particular workload result.
- Lexmark marks the exact product discontinued, and any offer's condition and toner region need separate checking.

What the features mean for you
A true color MFP, with a specific fax caveat
Lexmark lists color printing, copying, and scanning for the MC3426i. Those functions let a shared device handle both new pages and paper originals, unlike the print-only C3426dw in the same family. Fax needs careful wording: the exact U.S. page describes optional cloud fax through etherFAX and says analog phone-line fax is not supported. A buyer who needs to send through a conventional telephone line should not treat this as an equivalent substitute. The finder marks the documented cloud-fax capability, while the review makes the subscription and phone-line limitation explicit.
Two-sided work covers output and document intake
Automatic print duplex turns sheets inside the printer for two-sided reports. Lexmark also lists a 50-sheet automatic document feeder with single-pass two-sided scanning, so both sides of a source page can be captured without manually flipping each sheet. These are different functions: a duplex printer does not necessarily have a duplex ADF, and this model documents both. For a small office processing contracts or multipage packets, that can shorten the paper-handling steps. Confirm that an actual unit's feeder is present and feeds correctly before relying on a used offer.
Connect over Wi-Fi or Gigabit Ethernet
Lexmark lists standard 802.11b/g/n wireless, Ethernet 10/100/1000Base-TX, and USB. That gives a workplace several ways to share the machine; choose the path that fits the network rather than assuming a cable is included. The product page notes that an Ethernet or USB cable is not included in the box, and mobile printing still depends on the network and device setup. These ports distinguish the MC3426i from wired-only MFPs while retaining a USB connection for a local workstation.
Use the recommended range, not the maximum duty cycle
Lexmark recommends 750 to 5,000 pages per month for the MC3426i and separately lists a maximum duty cycle up to 75,000 pages. The recommended range is the more appropriate basis for matching a routine; the maximum is not a suggested monthly target. The 26-ppm Letter rating and standard 250-sheet input support a small-to-medium workgroup, while optional trays can expand paper capacity. If normal output is near or beyond the recommended upper end, compare a device with a more suitable recommendation rather than stretching the maximum duty number into a promise.
Check lifecycle, supplies, and the exact U.S. part
Lexmark marks MC3426i discontinued. Its U.S. part number is 40N9650; the UK listing uses 40N9753, so do not carry the UK part into a U.S. product record. Lexmark also notes that replacement cartridges are region-specific. Before selecting any particular used or renewed unit, confirm the part label, inspect the ADF and duplex path, and verify supplies for the unit's region. Discontinued status does not establish that a listing is unavailable, nor does it establish price or condition; those details belong to the specific offer.
What else to compare
Choose a conventional fax MFP if phone-line fax is mandatory, or the C3426dw if the workflow only needs color printing.
Before you buy
Does the MC3426i have built-in Wi-Fi and Ethernet?
Yes. Lexmark lists standard 802.11b/g/n wireless and Gigabit Ethernet for U.S. part 40N9650.
Does it include regular analog fax?
No. Fax is an optional cloud service, and Lexmark says analog phone-line fax is not supported.
What monthly output does Lexmark recommend?
Lexmark recommends 750 to 5,000 pages per month and lists a separate 75,000-page maximum duty cycle.

The decision
The MC3426i combines color copy and scan, automatic two-sided output and intake, and standard Wi-Fi and Ethernet. Optional cloud fax and discontinued status are meaningful trade-offs.
