The Brother DCP-L1640W is a compact 3-in-1 monochrome laser multifunction device designed for use in home offices and small businesses. It combines printing, scanning, and copying functions in one device and is suitable for a monthly print volume of up to 2000 pages. The printing technology is based on laser, with output exclusively in black and white. The device is equipped with WLAN, Ethernet, and USB connectivity, enabling flexible integration into existing networks. Print speed is 20 pages per minute with a maximum resolution of 2400 x 600 DPI, ensuring clear and sharp output even for text documents. The first page is delivered within 10 seconds. Operation requires an internal memory of 128 MB to support print and scan job processing.

Applications
This device is suitable for small offices, home offices, or smaller departments requiring a compact, powerful, and network-capable solution for basic printing, copying, and scanning functions. The recommended monthly print volume of up to 2000 pages makes it an appropriate choice for moderate workloads. Integrated support for Apple AirPrint, Brother Mobile Connect, and Mopria Print Service also enables mobile printing from smartphones and tablets.

Functions and Features in Detail
The device offers a variety of printing functions, including N-in-1 printing (e.g., 2- or 4-page summary on one page), poster printing, booklet printing, and watermark printing. The toner save mode reduces consumption under lower demand. The copying function supports up to 99 copies per job, with a resolution of 600 x 600 DPI and zoom scaling from 25 to 400 %. The first copy is delivered within 16 seconds. The device features an automatic document feeder (ADF), enabling scanning and copying of multiple pages without manual input. The scanning function uses a flatbed scanner with an optical resolution of 600 x 1200 DPI and a maximum scan resolution of 19200 x 19200 DPI. The scanning technology is CIS, with an input color depth of 30 bit and output color depth of 24 bit. Scanning is possible into formats such as E-Mail, file, and image.

Technology Explained Simply
The printing technology is laser-based, where toner is transferred to the drum image via a laser beam. The maximum resolution of 2400 x 600 DPI ensures high sharpness, especially for text. A print speed of 20 pages per minute is sufficient for private and small office use. WLAN connectivity supports standards 802.11a, 802.11b, 802.11g, and 802.11n (Wi-Fi 4), ensuring stable wireless connections to routers and end devices. Wi-Fi Direct enables direct connections without a router. The Ethernet connection supports 10/100Base-T(X) with data rates of 10 and 100 Mbit/s. Power supply is via 220–240 V, with an average power consumption of 380 W during operation and 1 W in standby mode. The device features a 2-line LCD display for operation and status indication.

Compatibility and Accessories
The device is compatible with operating systems such as Windows, Mac OS, and Linux. The replacement consumable is toner TN1150. Paper handling supports formats including A4, A5, B5, 16K, Executive, Folio, Legal, and Letter. Paper weight ranges from 65 to 105 g/m². Total paper capacity is 150 sheets, with an output capacity of 50 sheets. Paper input is via a single tray. Integrated network functionality supports numerous protocols including DHCP, SNMP, IPP/IPPS, FTP, HTTP/HTTPS, TFTP, LPR/LPD, mDNS, Web Services (Print and Scan), as well as SMTP-Client and DNS Resolver. Security algorithms include 64-bit WEP, 128-bit WEP, WPA-PSK, WPA2-PSK, WPA3-SAE, SSL/TLS, and SMTP-AUTH.

Installation and Mounting
Installation is performed using the provided quick start guide. Connection is possible via USB, Ethernet, or WLAN. Network setup can be done via the integrated web interface or the Brother Mobile Connect app. Operation is via the LCD display, which shows basic functions such as printing, scanning, copying, and settings. Setup is possible for users without technical expertise.

Operational Advantages
The device features a compact design, low standby power consumption (1 W), and a low operating noise level of 52 dB (printing). Integrated support for mobile printing technologies such as Apple AirPrint and Mopria enables flexible use. Duplex printing is manually possible during printing, but not available for copying or scanning. The maximum paper size is A4, making it suitable for standard office and home use. The use of recycled paper is supported, enhancing sustainability. Integrated security via WPA3-SAE and SSL/TLS protects data transmission over the network.
