I have a Samsung CLP-620ND printer that has suddenly started making loud grinding noises every time it prints. It also blurs parts of the printouts most of the time as though something is smearing the toner prior to the paper reaching the fuser.
The service manual for this model of printer does not seem to cover noise, and the print quality troubleshooting in this manual does not seem to describe the problem. One review of the printer (that I can no longer find) suggested that the problem might be the paper transfer belt. Before I spend $130+ on a new paper transfer belt, I'd like to know if anyone agrees with this assessment.
What are the likely causes of this problem? How can I fix it? Are there parts I will need to replace?
3Pull it apart and look :-) Clear out the paper dust (which is slipery) check the rollers gears and belts, and the paper transfer conveyor belt. I would not spend a penny more on it, until I could attempt to discover the actual problem, a rip in the conveyor or something. Get a point light flashlight and start looking into the nooks and crannies for small torn papers or anything. Dont touch the heads, but the rubber rollers can be cleaned with a microfiber rag (no lint) and a mix using consumer ammonia. Spend extra time making sure things are seated and mate well too. – Psycogeek – 2012-04-24T15:14:05.727
