Our take
Lexmark maps part 40C9100 to the CS720de, a color laser printer designed for workgroup output. It prints up to 40 ppm in black and color, has integrated duplex, Gigabit Ethernet and 650 sheets of standard input. Lexmark recommends 1,500–15,000 pages monthly and lists optional expansion to 2,300 sheets. This is a print-only device, not an MFP, and its 80-pound weight makes it a fixed installation. Choose it for a wired color queue rather than a home desk or wireless-only placement.
A wired color workgroup needing fast print-only output, automatic duplex and a published medium-to-heavy monthly range..
Skip it if you need an MFP, Wi-Fi, compact placement or a residential-use device.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The 40 ppm black-and-color rating supports larger shared queues.
- Integrated duplex and a 650-sheet standard supply reduce routine handling.
- Gigabit Ethernet and a 1,500–15,000-page recommendation suit a wired workgroup.
What to weigh up
- It does not copy, scan or fax.
- The checked standard ports do not list built-in Wi-Fi.
- At 80 pounds, it needs a stable installation location.

Full review: how the features affect your choice
What the features mean for you
Color printing at workgroup speed
Lexmark identifies the CS720de as a color laser printer and rates black and color output up to 40 ppm. Part 40C9100 is the candidate's U.S. model clue. The product is built around printing rather than copy, scan or fax workflows, so an office should keep a separate scanner or MFP if paper intake is common. Lexmark's [U.S. CS720de specifications](https://www.lexmark.com/en_us/printers/printer/10170/Lexmark-CS720de) document the print engine and connection ports for the exact model family.
Automatic duplex with room to expand
The CS720de has integrated duplex and a standard 550-sheet tray plus a 100-sheet multipurpose feeder. That gives it 650 sheets before optional expansion, with optional trays raising the total to 2,300. Duplex reduces manual page turning; the larger tray set reduces reloading. Optional capacity should only be credited when the offered machine includes those trays. This arrangement is more at home in a fixed workgroup than on a small personal desk, especially given the device's 80-pound weight.
Ethernet for a shared color queue
Lexmark lists Gigabit Ethernet and USB ports. Ethernet supports a wired shared queue, while USB allows a direct host connection. The standard port list does not include built-in Wi-Fi, so wireless networking should not be assumed. A wireless add-on may be a separate option, but this profile describes the base model. For offices with a wired network, the connection suits a stationary printer; for wireless-only placement, choose a device with confirmed standard Wi-Fi instead.
Use the recommended workload interval
Lexmark recommends 1,500–15,000 pages monthly. The page separately lists a 120,000-page monthly duty-cycle maximum, which is a ceiling rather than a routine target. The recommended range is the fit measure relevant to sustained use. Speed, standard capacity and optional trays each describe different aspects of output and should not replace that range. A workgroup near the upper end can compare supplies and tray expansion; a lighter office may not need a printer of this size.
Plan a fixed installation
The CS720de is about 80 pounds and measures 16.4 by 18.7 by 19.65 inches. Those dimensions and weight affect placement, delivery and access for paper changes more than they would for a compact desktop model. Lexmark classifies it as a workgroup-level printer and notes that it is an FCC Class A device not intended for residential or domestic environments. Confirm that the setup, power and operating location suit a commercial office before building it into a home workflow.
Compare for your needs
For a home office choose a smaller model; for scan and fax add an MFP rather than expecting printer-only features.
