**Fast test:** Try copying a document directly from the printer. If copying works but printing does not, the printer hardware is likely fine. The issue is probably connection, driver, or device settings.

**Why it matters:** A quick power reset clears temporary printer memory, stuck jobs, and sleep-mode connection problems.

# Fix 2 — ☎️(+1) ↪ 866 490 0338 ↪ Check Ink Tanks, Paper, and Printer Lights

..# If It Prints Blank Pages

# Fix 7 — ☎️(+1) ↪ 866 490 0338 ↪ Install or Reinstall the Correct Brother Driver
