Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- 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 colour 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.

Questions that only have an answer for the Brother MFC-J5855DW
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
My Brother MFC-J5855DW is missing a colour 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 colour 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.
