The Brother DCP-L1660W is a compact 3-in-1 multifunction device of the category laser multifunction printer, designed for use in home environments and small offices. It combines the functions of printing, scanning, and copying in one device and operates with laser printing technology for monochrome output. The maximum print resolution is 2400 x 600 DPI, ensuring clear text and sharp graphics. The print speed is up to 20 pages per minute at normal quality, with the first page ready in approximately 10 seconds. The device supports manual duplex printing, enabling double-sided printing by manually flipping the page. Additional print functions include N-in-1 printing, booklet printing, poster printing, and watermark printing, increasing flexibility in document creation. The toner save mode reduces consumption and lowers operating costs.

Applications
This device is particularly suitable for small offices, home offices, or private users requiring a compact, powerful solution for everyday printing and scanning tasks. The recommended monthly print volume is between 0 and 2000 pages, sufficient for low to medium workloads. The integrated automatic document feeder (ADF) with a capacity of 10 sheets facilitates scanning and copying of multi-page documents. Paper handling supports formats such as A4, A5, B5, 16K, Executive, Folio, Legal, and Letter, with paper weight ranging from 65 to 105 g/m². The device features a paper tray with a capacity of 150 sheets and an output tray for 50 sheets.

Functions and Features in Detail
The device offers a color scan function with an optical resolution of 600 x 1200 DPI and a maximum scan resolution of 19200 x 19200 DPI. The scanner type is a flatbed & ADF scanner operating with CIS scanning technology. The scanning speed is 12 pages per minute in black and white and 6.4 pages per minute in color. The scan function allows scanning to email, file, or image. The copy function supports a maximum resolution of 600 x 600 DPI, zooming from 25 to 400 %, and a maximum copy count of 99. The first copy is ready in approximately 16 seconds. The N-in-1 copy function enables creating 2- or 4-page copies on a single sheet.

Technology Explained Simply
The printing technology is based on laser technology, which uses toner and a drum. Print quality is determined by the resolution of 2400 x 600 DPI, where the horizontal resolution (2400 DPI) ensures sharp text and the vertical resolution (600 DPI) provides sufficient detail reproduction. The integrated 128 MB memory capacity enables processing of more complex documents. The device features a 2-line LCD display showing basic information such as status, error messages, and menu options. The noise level is 52 dB during printing and 18 dB in standby mode.

Compatibility and Accessories
The device is equipped with WLAN (802.11a/b/g/n, Wi-Fi 4) and Ethernet/LAN (10/100Base-T(X)), allowing both wired and wireless network integration. It supports Wi-Fi Direct for direct connections without a router. Network functions include protocols such as IPP/IPPS, SNMP, LPR/LPD, FTP, HTTP/HTTPS, TFTP, mDNS, DNS Resolver, DHCP, APIPA (AutoIP), ICMP, SMTP Client, SNTP Client, Web Services (Print and Scan), as well as IPv4 and IPv6. Security is ensured by algorithms including 64-bit WEP, 128-bit WEP, WPA-PSK, WPA2-PSK, WPA3-SAE, SSL/TLS, SMTP-AUTH, and IP address filtering. For mobile use, Apple AirPrint, Brother Mobile Connect, and Mopria Print Service are available. Compatible operating systems include Windows, Mac OS, and Linux.

Installation and Mounting
Installation is performed via integrated interfaces: USB 2.0, WLAN, and Ethernet. Setup is possible via the LCD display and network options. The included quick start guide assists the user with configuration. Power supply is via mains voltage (220–240 V), with power consumption of 380 W during operation and 1 W in standby mode. The device features an energy-saving mode.

Operational Advantages
The device features a compact design (38.5 cm width, 34 cm depth, 28.3 cm height, weight 8.2 kg) and easy operation. The combination of ADF, WLAN, Ethernet, and USB enables flexible integration into existing work environments. Support for mobile printing and network functions increases productivity. Consumables consist of the toner TN1150 (approx. 1000 pages) and the drum DR1150 (approx. 10,000 pages). The included starter toner allows approximately 350 pages. The device is designed for use in private households and small offices and complies with the ear category 6 (small IT and telecommunications devices).

Scope of Delivery
The device is delivered with the Brother DCP-L1660W 3in1 multifunction printer, a starter toner (approx. 350 pages), a power cable, and a quick start guide.
