Hi, I'm having trouble fixing a constant toner leak on a MP3351. I put in a new hopper and a type 1027 PCU. Not to mention that I made sure that the hopper and PCU are in constant contact with each. I played with toner settings and nothing is working. The machine has 200k. I've been dueling with this for about six months and every 3-4 weeks I have to go vacuum up this mess. I have to pull out the laser each time I'm there. Any advice is appriciated, Thanks.
