What is true of this model and changes how you fix it

Official specifications
30 ppm black and color (Brother MAXIDRIVE), 4800x1200 dpi. Prints up to 11x17in (ledger/A3) — the widest format in this catalog's inkjet lineup. INKvestment cartridges rated for up to 1 year of ink in-box. 250-sheet tray + 100-sheet multipurpose tray, 50-sheet ADF.
Type — business INKJET all-in-one (up to 11x17)
A business INKJET AIO that prints up to 11x17 (ledger/A3). Being inkjet, the printhead can CLOG if unused — faded/streaked output is usually a clog; run the printer's print-head cleaning. It uses Brother ink cartridges (INKvestment/high-yield on many J-series for lower cost).
Cartridges & clogs
A missing color is a clog or an empty/unseated cartridge; run a print-quality check and cleaning. Don't leave it idle for long periods.
Connectivity
Wi-Fi/Ethernet/USB; 'offline' is usually a Wi-Fi drop or wrong queue.
Tabloid
It prints up to 11 x 17 in (ledger) and does automatic duplex, but borderless is not available with duplex.
Paper
A 250-sheet standard tray and a 100-sheet multipurpose tray.
Ink yields
Standard cartridges give 3,000 black and 1,500 color pages, and XL cartridges 6,000 black and 5,000 color pages.
Connectivity and size
Ethernet, dual-band wireless, Wi-Fi Direct and USB 2.0, at 21.5 x 17.2 x 12.0 in and 39 lb.
Label and serial
The MFC-J5855DW is a Brother business inkjet that prints on up to A3 sizes. Its serial number is on a label at the back. Brother's support uses it for warranty checks.
Ink
It uses high-yield cartridges. When one is empty, Brother's printer may refuse to print in color, so keep a spare. Install cartridges in the right slots, and do not touch the contacts.
Paper handling
The printer has trays for several sizes. Slide the guides to the paper and do not mix sizes. A3 sheets need the manual feed or the right tray.
Maintenance and cleaning
Brother's business inkjets run a cleaning when you ask. Use it only when you see faint lines, since it uses ink. Print a test page first to see which color is missing. Keep the printer on, since it protects the heads when idle.
Network and administration
The printer has an administrator page on its address. Set a password and check the firmware. Use Brother's mobile app to print and scan from a phone.

Questions that only have an answer for the Brother MFC-J5855DW

My Brother MFC-J5855DW is missing a color or printing streaky.+

That is an inkjet printhead clog — unlike Brother's lasers, the J-series is inkjet, so it clogs if idle. From the printer menu run the Print Quality Check and then Print Head Cleaning (repeat if needed), printing a check pattern to see improvement. Confirm the cartridge for the missing color has ink, is genuine/seated, and had its tape removed if new. Print regularly to prevent clogs. Stubborn clogs may need several cleans or a deeper clean cycle.
