Lexmark E250d: local monochrome duplex printing review

A local printer with real automatic duplex

The Lexmark E250d is a monochrome laser printer for a computer desk where black-and-white output and automatic two-sided printing matter more than shared-network features. US part 33S0100 includes USB Type-B and parallel interfaces, a 250-sheet drawer and an integrated duplex mechanism. Its recommended workload is 250–2,200 printed pages per month.

The d configuration is important: it does not include the Ethernet interface of the E250dn. External network and wireless print servers appear as options, not supplied connections. It is also a print-only device. The paper drawer and manual slot cannot scan originals, make standalone copies or send a fax.

Set the driver for the document

The original guide explicitly permits automatic duplex on Letter, Legal, A4 and Folio paper. That is stronger evidence than simply finding Legal in a list of printable sizes. In compatible computer software, choose two-sided printing and the required long-edge or short-edge binding, then select the appropriate paper source and size.

Check a short document with text on both faces before committing a larger stack. Letterhead orientation changes with the printing arrangement, and an incorrect binding choice can turn the back of a page upside down. Other specialty media should follow their separate instructions rather than being sent through automatic duplex just because the printer can accept them in simplex.

Lexmark declares up to 30 one-sided Letter pages per minute, compared with 28 on A4. Automatic Letter duplex is separately rated at up to 14 sides per minute. These are different operating modes, and neither is a measured promise for a particular application, large graphic file or complete office job.

Use the drawer for stacks and the manual slot for exceptions

The supplied drawer holds 250 ordinary sheets at the stated 20-pound or 75-gsm basis. Letter, Legal and A4 each fit that capacity. For Legal paper, release the rear latch, extend the drawer and provide room behind the machine for the extension and dust cover. Adjust the guides and match the driver settings to the actual load.

The front manual feeder accepts one item at a time. It is useful for a sheet of different stock or an occasional suitable envelope without unloading the main drawer. Set the correct size and type, position the item as instructed and allow the feed mechanism to engage without forcing it. Envelopes use a one-sided routine and must meet the laser-media requirements.

The rear exit offers a straighter path for certain specialty media. Opening it changes where sheets emerge, so leave clear space behind the printer. The 800-sheet maximum input requires the optional 550-sheet drawer; it does not describe the supplied 250-sheet configuration. The separate output bin holds up to 150 ordinary sheets.

Understand the lights before something needs attention

The E250d uses five lights and two buttons rather than a text display. Light combinations communicate paper, toner, photoconductor and other conditions. Keep the original quick-reference information accessible, and use the computer's Local Printer Settings Utility where an adjustment is unavailable in the normal driver.

The exact d model lists PCL 5e and PCL 6 emulations. Do not assume it supplies the E250dn's additional PostScript support. Check the actual computer's printer software and application output before purchasing an earlier machine. AirPrint, Mopria and protected-job PIN release are not established features in this assessment.

Inspect supplies and condition together

The original US package includes a 1,500-page Return Program starter toner cartridge. Compatible US and Canadian E250A11A or E250A21A replacements declare 3,500 pages under ISO/IEC 19752. The separate E250X22G photoconductor is rated at 30,000 pages on an approximately 5% coverage basis. These figures refer to different components and measurement conditions.

One useful maintenance detail is that the normal Toner Low light sequence does not appear with the 1,500-page starter cartridge. Inspect print output and installed supplies rather than relying only on that warning. A mismatched cartridge region is another documented error condition.

Lexmark marks this 25-pound printer discontinued. Check the electrical label, appropriate supplies, software support and physical condition, and allow operating access beyond the closed-body dimensions. Choose an E250dn when included wired sharing is necessary, or a newer explicitly documented model when wireless or mobile printing is essential.
