Brother MFC-7840W

Quick view

The Brother MFC-7840W is a multifunction monochrome laser printer designed for small office and home office use, integrating printing, copying, scanning, and faxing functions. It utilizes a 600 x 600 dpi laser print engine capable of delivering sharp and clear monochrome documents at speeds up to 24 pages per minute (ppm). The device incorporates wireless 802.11b/g connectivity alongside USB 2.0, allowing versatile connection options for networked environments. The scanning module employs a CIS sensor with optical resolution up to 600 x 2400 dpi, facilitating high-quality scan jobs. Additionally, the built-in fax capability supports Super G3 transmission for faster data transfer, enhancing communication efficiency. This model features a paper input capacity of up to 250 sheets and an automatic document feeder (ADF) that supports up to 35 sheets, enabling efficient batch processing.

The MFC-7840W offers wireless network capability, providing flexible installation without the need for physical network cables. It combines four essential office functions in a single compact device, conserving space and reducing overall costs. The laser printing technology delivers high speed and sharp output, suitable for professional document needs. Energy-efficient design helps reduce power consumption during operation and standby modes. The automatic duplex printing feature increases productivity while saving paper. With its reliable fax modem and robust build quality, it suits busy office workflows and ensures durability over time.

As a monochrome printer, the MFC-7840W is limited to black and white output, restricting color document needs. The print resolution of 600 x 600 dpi, while sufficient for text, may not meet requirements for high-resolution graphic printing. Wireless protocols supported are limited to 802.11b/g without newer standards like 802.11n/ac, affecting potential performance in modern networks. The scanner's optical resolution and color depth are moderate compared to dedicated scanners, limiting advanced imaging tasks. The paper capacity and speed may not be adequate for very high volume printing environments. Additionally, no support for mobile device printing protocols such as Apple AirPrint or Google Cloud Print is provided due to its older technology base.
