Brother DCP-8155DN: single-pass Legal scanning over a wired network review

Two useful Legal scanning routes in a wired machine

The Brother DCP-8155DN is an earlier monochrome laser printer and copier whose strongest document-handling argument is its scanner. It captures color, accepts Legal originals on the glass and has a 50-page ADF that scans both sides simultaneously in one pass. For a compatible office digitizing two-sided contracts, that combination avoids choosing between a short flatbed and a feeder with no automatic reverse-side capture.

Its standard computer connections are USB and Ethernet. Plan the network cable, suitable desktop scanner software and physical access before choosing it. Brother marks the model discontinued; its original operating capabilities do not establish present stock or guarantee support for every current operating system. The exact configuration is print, copy and scan, despite stray fax fields in the current generic product table.

What the 8155 suffix adds to the scanning routine

The USA family manual makes the model distinction explicit. The DCP-8155DN column supports automatic duplex scanning, while the neighboring 8110DN and 8150DN columns do not. The exact US product description additionally identifies simultaneous single-pass capture. Those two readings establish the feature without borrowing it from another printer or assuming that automatic two-sided printing implies a two-sided scanner.

Suitable duplex originals can measure 5.8–8.5 in. wide and 5.8–14 in. long. The glass accepts up to 8.5 × 14 in., so a Legal sheet unsuitable for feeder travel has a documented flatbed alternative. Keep the ADF empty when using the glass, fan a suitable loose stack and avoid stapled, damaged or pasted originals. The original Windows scan-to-file procedure exposes separate long-edge and short-edge duplex settings; choose the setting that matches the original document.

Included paper handling and a US duplex restriction

The 250-sheet main cassette and 50-sheet multipurpose tray provide 300 sheets of included print input on the specified 20 lb plain-paper basis. Both routes accept the dimensions needed for Letter, Legal and A4. The optional 500-sheet LT-5400 is a separately purchased expansion. A capacity requirement for the normal printer should therefore use 300, even though an expanded machine can hold more.

The US automatic print-duplex list is narrower than the simplex paper list: it names Letter, Legal and Folio. A4 support in the main tray and A4 two-sided scanning do not prove automatic A4 output. Brother rates the US machine at up to 40 one-sided Letter ppm, with a separate duplex rating of 18 sides or 9 sheets per minute on Letter. Neither number is a scanning rate or a result measured for this article.

AirPrint through Ethernet is a real arrangement

The linked AirPrint guide explicitly shows a printer connected by network cable to a wireless access point/router, with the mobile device on the shared wireless network. That makes AirPrint a supported possibility for this wired model without inventing a built-in radio. It does not make a USB desktop connection an AirPrint connection, or establish Wi-Fi Direct.

Desktop scanning over Ethernet has its own positive support in the USA guide, including driver installation and TCP/IP configuration. The original Server rows are network printing only, so server printing support should not be used as evidence of scanner software. The control-panel Secure Print key releases compatible stored print data using a four-digit password. This is distinct from the scan-destination PIN and administrator user restrictions.

Supplies, body fit and the regional paperwork

The USA 8155 inbox toner declaration is approximately 3000 pages. TN-720 and TN-750 replacement declarations are 3000 and 8000 pages under ISO/IEC 19752; DR-720 is a separate drum with an approximate 30000-page declaration at one page per job. These manufacturer figures are not remaining life for an individual machine or a current cost estimate.

Use the actual USA power and dimensions:110–120 V AC, a 19.3 × 16.3 × 17.6 in. body and 36.4 lb with consumables. Allow room for tray extension, document loading and service access. A preserved Australian brochure uses different toner identities and monthly-volume guidance; its printed 6.5 kg weight also conflicts with the US16.5 kg figure. Those regional values are not substituted here. If built-in wireless or color output matters more than Legal scanning, choose a configuration that explicitly supplies those functions.
