Brother MFC-L2710DW
is not printing black.
Brother MFC-L2710DW is not printing black? Missing black usually points to a blocked nozzle, an empty or unseated black supply, or a setting that routes black text through the wrong path. On this laser model, check Brother iPrint&Scan, TN-730 or TN-760 toner seating, ADF feeding, and duplex path first.
Try these in order.
Stop as soon as the printer behaves. Each step removes one likely cause without changing settings you may need later.
- Black text is faint, gray, or missing while color prints
- A test page shows uneven or streaky black
- The toner indicator reports low or empty
- Brother MFC-L2710DW behavior points back to Brother iPrint&Scan, TN-730 or TN-760 toner seating, ADF feeding, and duplex path.
- 01
Print a supplies status page
Print the supplies or toner status page before replacing anything. It separates toner remaining from drum life. On the Brother MFC-L2710DW, use Brother Mobile Connect for this check.
Expected result: The page shows whether toner or drum is the exhausted part.
- 02
Reseat the black toner and drum
Remove and reinstall the black toner cartridge and drum unit until they click. Confirm any protective strips were removed.
Expected result: The toner or drum indicator clears and black output returns.
- 03
Turn off toner-save mode
In the driver or panel settings, disable toner-save, economy, or draft mode and reprint the page at normal density.
Expected result: Black text prints darker without replacing any part.
Match your symptom, jump to the right fix.
If: The supplies page shows black toner empty
Then: Replace the black toner cartridge first.
If: Toner is fine but black is streaky or faded
Then: Check toner-save mode, then suspect the drum unit.
If: Black prints but is gray and uniform
Then: Turn off toner-save or economy mode before replacing parts.
Usually one of these.
- Brother iPrint&Scan, TN-730 or TN-760 toner seating, ADF feeding, and duplex path is the model-specific checkpoint to verify first.
- The black toner cartridge is empty, low, or not seated correctly.
- The drum unit is at end of life and no longer transfers black toner.
- The driver is using a draft, economy, or toner-save setting.
Move to the deeper fix.
Replace the black toner
If the supplies page shows black toner empty or very low, replace it with the correct cartridge for this model and reprint the test page.
Expected result: Black text prints at full density after the new toner is seated.
Replace the drum unit
If black remains streaky or faded after a fresh toner, the drum is likely at end of life. Replace it using the model guide. Use the official Brother support page for the exact Brother MFC-L2710DW package before changing firmware or resetting the device.
Expected result: Even, dark black output returns after the drum is swapped.
- Do not shake a toner cartridge to get more pages; it can spill toner inside the printer.
- Do not expose the drum unit to direct light for long, or pages may develop a repeating defect.
Before you reset everything.
Why is black printing faint on a laser printer?
Faint black usually means low toner, a toner-save setting, or a drum at end of life. Print a supplies status page to see which. On this model, start with Brother Mobile Connect and the official support instructions.
Is it the toner or the drum?
Toner and drum fail differently. Empty toner makes pages uniformly light; a worn drum makes repeating streaks or marks. The supplies page reports both.
Does toner-save mode make text look gray?
Yes. Toner-save and economy modes reduce toner use and make text noticeably lighter. Turn them off for normal output.
Can I use a compatible toner cartridge?
Compatible cartridges can work, but a faulty one is a common cause of faint output. Try a genuine cartridge if problems persist.
