Published specification
What is true of this model and changes how you fix it
- Official specifications36 ppm, 1200x1200 dpi, scan speeds up to 23.6/7.9 ipm (black/color). 50-page ADF, 250-sheet tray, dual-band Wi-Fi + Ethernet. Has scan and copy but Brother's own DCP-line naming confirms NO fax hardware — same 36 ppm engine as the print-only HL-L2460DW.
- Type — MONOCHROME LASER all-in-one (no fax)A black-and-white laser AIO with print/scan/copy but NO fax (the DCP line drops fax versus MFC). Black-only by design.
- Toner & drum are separateSeparate toner cartridge and drum unit; a drum message/reset is separate from toner. Faded print is low/unseated toner; streaks are the drum.
- ConnectivityWi-Fi/USB; 'offline' is usually a network/queue issue.
- What owners run intoPrinters that show offline after an address change, faded or streaked pages from low toner or a dirty drum wire, and maintenance messages that need a counter reset.
- How to approach a faultCheck the printer's Wi-Fi status, run a WLAN report, give the printer a fixed address and clean the corona wire with the green tab before replacing parts.
- ConsumablesToner and drum have different lives. Replace toner when it is low and the drum when its message appears, and reset the counter after replacing the drum.
- SupportBrother's support site lists drivers, the iPrint and Scan app and the user guides for this model.
- Scanning and copyingThe scanner glass and the document feeder need to be clean for good copies, and streaks on copies but not prints point at the glass, not the toner. Use Brother's iPrint and Scan app or Windows Scan to scan to a computer, and set the scanner to use the printer's IP address so that it keeps working after a router restart. Keep paper dry in a sealed packet, and fan it before loading to avoid jams, since damp paper is a leading cause of poor print quality on laser printers.

Exact questions
Questions that only have an answer for the Brother DCP-L2640DW
How do I send a fax from my Brother DCP-L2640DW?+
You can't — the DCP line does not include fax (that is the MFC line). The DCP-L2640DW does print, scan and copy, but has no fax feature, so there is nothing to set up or troubleshoot for faxing. If you need fax, a Brother MFC-series model has it. For everyday black-and-white printing, scanning and copying, the DCP is a reliable, low-cost laser, with separate toner and drum parts.
Does it print double-sided?+
Yes, automatically.
How do I clean the corona wire?+
Slide the green tab on the drum unit back and forth.
Why does it go offline?+
The address or the network changed.
Do I reset the drum counter?+
Yes, after a replacement.
