Brother MFC-J1012DW
is not printing black.
Brother MFC-J1012DW 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 inkjet model, check Brother Mobile Connect, LC401 cartridges, flatbed scanning, and duplex feed 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 blank while color still prints
- A nozzle check has missing black segments
- Black areas look gray, streaked, or uneven
- Brother MFC-J1012DW behavior points back to Brother Mobile Connect, LC401 cartridges, flatbed scanning, and duplex feed.
- 01
Run a quality or nozzle check
Print the built-in quality page before cleaning. It shows whether the failure is isolated to black and gives a baseline for the next check. On the Brother MFC-J1012DW, use Brother Mobile Connect for this check.
Expected result: The check shows black missing while other colors fire normally.
- 02
Reseat or replace the black cartridge
Remove and reinstall the black cartridge until it clicks, and confirm it is not empty. Replace it if the ink level reads empty.
Expected result: The cartridge indicator clears or the ink level reads above empty.
- 03
Run one standard cleaning
Use one normal printhead cleaning cycle, wait for it to finish, and print the quality check again before trying a deeper routine.
Expected result: A follow-up quality check shows the black nozzles firing.
Match your symptom, jump to the right fix.
If: Color prints but black is blank
Then: The black path is isolated. Reseat the black cartridge and run a nozzle check.
If: The black cartridge is empty
Then: Replace it, then run a single cleaning cycle to clear the air.
If: Black prints but looks gray or faint
Then: Check paper type and draft settings before cleaning the printhead.
Usually one of these.
- Brother Mobile Connect, LC401 cartridges, flatbed scanning, and duplex feed is the model-specific checkpoint to verify first.
- The black nozzle or printhead has dried ink buildup.
- The black cartridge is empty or not seated correctly.
- The driver is using a draft, composite-black, or incorrect paper setting.
Move to the deeper fix.
Check the paper and driver settings
Choose the correct paper type, turn off draft mode, and confirm the document is not set to color-only or composite-black behavior.
Expected result: Black text prints with the intended density.
Use the official deep-clean routine
Follow the manufacturer sequence for deep cleaning or printhead alignment once. Stop if the guide warns that repeated cycles can damage supplies. Use the official Brother support page for the exact Brother MFC-J1012DW package before changing firmware or resetting the device.
Expected result: Black output is restored after one deeper cleaning cycle.
- Do not keep running cleaning cycles. Start with one and only escalate if there is no change.
- Do not rub the printhead contacts with anything abrasive; use the maintenance routine instead.
Before you reset everything.
Why do colors print but black does not?
Black uses a separate nozzle, cartridge, or tank channel. A color page can look normal even when that black path is blocked or empty. On this model, start with Brother Mobile Connect and the official support instructions.
Should I keep running cleaning cycles?
No. Start with one standard cycle and a quality check. If there is no change, use the model-specific deep-clean or service instructions once.
Can a bad paper type setting cause faint black?
Yes. A glossy or heavy paper setting changes how much ink is laid down and can make black look gray.
Does a draft mode make black look faded?
Yes. Draft mode uses less ink. Switch to normal quality and reprint the same page.
