Got it š Youāre using a Canon LBP612C/613C color laser printer, and youāre seeing magenta (pink) dots or specks on your printed pages ā 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. Hereās a complete guide to fix it š
š Likely Causes edit
- 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, youāll 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 isnāt properly fused (heated), small specks can appear ā but this is less common for magenta-only issues.
š§¼ Step-by-Step Fix edit
1ļøā£ Clean Inside the Printer edit
- 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 ā that spreads toner everywhere.
2ļøā£ Inspect Toner Cartridges edit
- 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 ā if yes, itās faulty.)
- Reinsert the cartridges and close the panel.
3ļøā£ Print a Test Page edit
- Go to printer settings ā maintenance ā print quality page.
- Check if magenta dots still appear. - If they do, itās not just a surface leak ā move to the next step.
4ļøā£ Clean the Transfer Belt (if accessible) edit
Some Canon LBP printers have a maintenance menu or allow a ācleaningā cycle:
- On the printerās control panel or web interface (type 192.168.4.27 in your browser), go to: > Settings ā Maintenance ā Clean Fixing Assembly / Clean Transfer Belt
- Run the cleaning cycle 1ā2 times.
5ļøā£ If the Problem Persists edit
- 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 20kā50k prints). - You may need to replace the magenta drum or transfer unit.
āļø Extra Tip edit
You can check Print Quality Report in Canonās web interface:
- Open: http://192.168.4.27
- Login (if prompted, default user: admin, password: blank or admin).
- Go to Reports ā Print Quality / Supplies Info.
- See which cartridge or part shows abnormal wear.
š” Summary edit
| 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. āCartridge 054ā or ā054Hā).
Would you like me to check that for your Canon LBP612C/613C?
