Got it 👍 You’re using a Canon LBP612C/613C color laser printer, and you’re seeing magenta (pink) dots or specks on your printed pages — like in the first image.
This is a very common issue in color laser printers and is usually caused by toner leakage, a damaged drum unit, or a dirty transfer belt. Here’s a complete guide to fix it 👇
🔍 Likely Causes[edit | edit source]
- Toner Cartridge Leak (Magenta) - The magenta toner cartridge may be leaking or have loose toner inside. - Over time, toner dust escapes and sticks to rollers or the transfer belt.
- Dirty or Contaminated Transfer Belt - The transfer belt moves toner from the cartridges to the paper. - If magenta toner dust is stuck on it, you’ll get scattered pink/magenta dots.
- Imaging Drum Damage - Each color has a drum inside (either built-in or separate). - A scratched or contaminated magenta drum can cause repeated spots or streaks.
- Fuser Unit Issue - If toner isn’t properly fused (heated), small specks can appear — but this is less common for magenta-only issues.
🧼 Step-by-Step Fix[edit | edit source]
1️⃣ Clean Inside the Printer[edit | edit source]
- Turn off and unplug the printer.
- Open the toner access panel and carefully remove all toner cartridges.
- Use a soft, lint-free cloth or a slightly damp microfiber cloth to gently wipe any visible toner residue.
- If you have a small handheld vacuum (for electronics), you can use that to remove loose toner dust.
- Avoid blowing air inside — that spreads toner everywhere.
2️⃣ Inspect Toner Cartridges[edit | edit source]
- Check the magenta cartridge carefully. - Look for cracks, leaks, or toner build-up around the drum surface or roller.
- If the cartridge looks dusty or leaking, replace it. - (You can also gently tap it over a bin to see if toner leaks out — if yes, it’s faulty.)
- Reinsert the cartridges and close the panel.
3️⃣ Print a Test Page[edit | edit source]
- Go to printer settings → maintenance → print quality page.
- Check if magenta dots still appear. - If they do, it’s not just a surface leak — move to the next step.
4️⃣ Clean the Transfer Belt (if accessible)[edit | edit source]
Some Canon LBP printers have a maintenance menu or allow a “cleaning” cycle:
- On the printer’s control panel or web interface (type 192.168.4.27 in your browser), go to: > Settings → Maintenance → Clean Fixing Assembly / Clean Transfer Belt
- Run the cleaning cycle 1–2 times.
5️⃣ If the Problem Persists[edit | edit source]
- Try replacing the magenta toner first (most common fix).
- If it still happens, the drum or transfer belt may be contaminated or near end-of-life. - These parts have page life cycles (usually 20k–50k prints). - You may need to replace the magenta drum or transfer unit.
⚙️ Extra Tip[edit | edit source]
You can check Print Quality Report in Canon’s web interface:
- Open: http://192.168.4.27
- Login (if prompted, default user: admin, password: blank or admin).
- Go to Reports → Print Quality / Supplies Info.
- See which cartridge or part shows abnormal wear.
💡 Summary[edit | edit source]
| Cause | Fix | | --------------------- | ------------------------------------ | | Magenta toner leaking | Replace the magenta toner cartridge | | Dirty transfer belt | Run cleaning cycle or manually clean | | Drum unit damaged | Replace the drum (if separate) | | Loose toner inside | Clean interior carefully |
If you tell me whether your printer uses combined toner + drum cartridges or separate drums, I can give the exact Canon part number for replacement (e.g. “Cartridge 054” or “054H”).
Would you like me to check that for your Canon LBP612C/613C?
