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 ====
# 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 ====

===== 1️⃣ Clean Inside the Printer =====
# 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 =====
# 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 =====
* 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) =====

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 =====
* 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 ====

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 ====

| 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?
