==== 🧼 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.
