Our take
Lexmark identifies part 34T5012 as the X748de, a color laser multifunction printer with copy, scan and fax as well as printing. Its U.S. page lists integrated print duplex, up to 35 ppm Letter in black and color, a 50-sheet reversing duplex ADF, Gigabit Ethernet and a 3,000–10,000-page recommended monthly volume. Wireless is an optional network port, not standard built-in Wi-Fi. Lexmark marks the model discontinued and describes a 97.5 lb machine with 650 sheets of standard input. This is a wired workgroup MFP rather than a compact color printer.
A wired team needing color print/copy/scan/fax, two-sided document handling and a recommended workgroup workload..
Choose another product if standard Wi-Fi, a light personal footprint, print-only simplicity or continued current-model support is essential.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Lexmark maps 34T5012 to a color MFP with print, copy, scan and fax.
- The 50-sheet reversing duplex ADF handles both sides of originals, separate from print duplex.
- The 3,000–10,000-page monthly recommendation and standard Ethernet are documented.
What to weigh up
- Wireless requires an optional internal port rather than coming standard.
- The discontinued unit is large and heavy for a personal desk.
- The recommended range can exceed the needs of occasional color printing.

What the features mean for you
Color output with a complete document workflow
Lexmark documents color printing, copying, scanning and faxing for the X748de. That makes it a candidate for a team that needs to move paper originals through several tasks without walking to separate devices. Part 34T5012 identifies the exact U.S. configuration; check the nameplate because similarly named X748 models can include different feeder or tray options. A print-only desk would not benefit from every function and might prefer a smaller device. Consider the routine first: the X748de's strongest case is a shared, wired office that uses its MFP functions regularly.
Duplex printing and duplex scanning are both documented
Lexmark lists integrated duplex printing and a 50-sheet RADF, or reversing duplex automatic document feeder. Print duplex turns outgoing sheets; the reversing feeder handles two-sided originals for scanning. Keeping those functions separate helps a buyer check the right paths on a used machine rather than assuming one proves the other. The sheet reports duplex scan output speeds, but real throughput depends on job content and setup. If the office digitizes double-sided forms, feeder capacity and the reversing mechanism matter as much as the print engine. Test both workflows before relying on them.
A workgroup range and a consistent speed rating
Lexmark rates the X748de up to 35 ppm Letter in both black and color and recommends 3,000–10,000 pages per month. That band offers a clearer planning point than a maximum duty-cycle figure, and it places the model above a light personal routine. Compare the lower and upper recommendation with expected volume and spikes. The listed 100,000-page maximum monthly duty cycle is not a suitable substitute for the recommendation. A used printer's remaining life also cannot be inferred from the published range, so inspect its output and maintenance state separately.
Ethernet is standard; Wi-Fi is an add-on
Lexmark lists 10/100/1000 Ethernet as a standard port and wireless through an optional internal MarkNet adapter. That makes the standard model a wired network printer, while wireless placement depends on the exact accessory being present and supported. USB is also available for local connections. Verify the configured ports, office security policy and driver support on the actual device. A product title or the general X748 family should not be used to assume Wi-Fi. For a team with reliable Ethernet, the standard configuration gives a straightforward shared path without making a wireless claim.
Paper handling and footprint favor a team room
The X748de has 650 sheets of standard input: a 550-sheet tray and 100-sheet multipurpose feeder. Lexmark lists optional drawers and a high-capacity feeder that can expand the machine, but those accessories should be checked rather than assumed. At roughly 31 inches high and 97.5 pounds, the unit needs a stable location and access for servicing. The paper supply can reduce interruptions in a recurring office routine, while its bulk can be wasteful in a small room. The model's Class A commercial marking also points toward an office environment rather than a quiet residential desk.
Discontinued status raises the value of inspection
Lexmark marks the X748de discontinued. That does not settle the condition, price or availability of any specific unit. Inspect color output, toner levels, scan glass, ADF rollers, duplex paths, fax line connections and Ethernet before depending on it. Confirm all required accessories and supplies from current manufacturer information and check driver compatibility with the team's systems. The article uses the manufacturer's documented configuration and does not infer that any used listing includes toner, a warranty or service. If ongoing support simplicity is a priority, a current MFP can be a safer operational match even when its feature list is shorter.
What else to compare
Choose a wireless color MFP if Wi-Fi must be standard, or a smaller print-only model if paper capture and fax are unnecessary.
Before you buy
Does the X748de include fax?
Yes. Lexmark lists fax among the functions of the exact X748de color MFP.
Can its ADF scan both sides?
Yes. Lexmark specifies a 50-sheet reversing duplex ADF on the X748de.
What monthly page volume does Lexmark recommend?
Lexmark recommends 3,000 to 10,000 pages monthly for this model.
Is wireless networking standard?
No. Ethernet is standard, while the wireless network port is an optional accessory.
