Brother HL-4150CDN Colour Laser Printer 24/25 ppm 384 MB 300 sheets

Purpose and audience

The Brother HL-4150CDN is a desktop colour laser printer built for small workgroups that need fast, automatic duplex output on plain paper. It prints up to 25 pages per minute in monochrome and 24 pages per minute in colour with a 2400 x 600 dpi resolution. Standard memory of 384 MB and a 400 MHz processor handle typical office documents without extra upgrades. An LCD panel enables PIN-protected printing for sensitive files.

Sustained workload behaviour

The engine is rated for a maximum duty cycle of 40000 pages per month, so it can maintain daily throughput well beyond occasional bursts. Standard input capacity is 300 sheets and can be expanded to 800 sheets, reducing reload frequency during long print runs. Automatic two-sided printing cuts paper consumption by up to 75 percent, supporting continuous double-sided jobs without manual intervention. Ethernet and USB interfaces keep the queue moving across multiple users.

Thermals noise and power

As a desktop laser unit, it operates at typical office noise levels while the fuser warms for each job; no specific acoustic or power figures are supplied. The 250-sheet standard tray and 300-sheet output bin keep the footprint compact for desk placement. Automatic duplexing reduces paper handling, which indirectly limits repeated warm-up cycles. Network sharing via built-in Ethernet avoids extra host computers that would add heat and noise.
