This is my last hope to find this issue, the fuser is making a banging sound for like a couple of seconds when booting or when you start to print something initial at the beginning so when you pause printing and go back to printing a little later it makes the banging sound again then stops, ive tried a different fuser unit same issue, ive checked all the gears and motors nothing is broken, the print results are fine aswell, maybe could be a home position sensor but idk please help.

Are you sure its the fuser? Sometimes a banging or gear mesh noise (loud) could be from a binding transfer belt cleaning unit because the waste transfer bottle hasn't open the shutter properly and waste toner backs up and binds up the transfer cleaning mechanism.

Yeah ideally we need to hear the noise. Easy to record it and upload somewhere in web. Plus some more BASIC information won't hurt you.A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.

A cust sent a video of the loud noise and in sounded like the ru-513 was slipping or something but it wasn't the noise was intermittent and would happen at the start of jobs sometimes. A hunch led me to the belt cleaning unit although the loud noise almost sounds like it comes from the fuser area at first.

If it makes the noise a job start and finish. Take a screwdriver and put the tip of it on the lower right of the fuser drive where the cam gear goes through the frame and give it a couple of hits with the palm of you hand. It will move the gear that cams the fuser a couple of MM closer and stop your noise. Most of the machines I've heard a knocking noise on also gives a fuser cam error.Comment

Is this a new install or have you recently changed the fuser?
It's been a long time since we've had this, but some of the earlier machine we received would make a loud banging noise when powering on, and just before feeding paper when they were new out of the box. It was caused by the fuser pressure drive gears slipping. The gear that sticks out through the rear frame that meshes with the gear on the fuser itself. We were never able to determine if it was a manufacturing problem or if the machines got roughed up a bit too much in transport. This might be what you have going on. Pull off the back panel on the machine and watch to see if that seems to be what is going on.
How we fixed it was to tweak the metal plate on the fuser drive unit so that the shaft that goes through the frame meshed better with the gear on the fuser. This was accomplished by taking a philips screwdriver and placing it on the metal plate of the drive unit in 2 different places and tapping the handle of the screwdriver with a wrench or something similar to slightly flex the plate. The few machines we've had with this issue have never had the problem return, and some of them have been out in the field for 3+ years.
Below is a picture with red dots in the area where we would tap the metal plate to tweak it. Start out with light taps, it if still slips, go a bit more. You don't want to bend it too much, just a little bit otherwise the gears might be too tight together or you may end up wearing out the bushings on each end of the shaft.

I re-read your post, and yes, that is exactly what you said. I guess I wasn't paying attention when I read it the first time around.
I think we might have had a total of 5 or 6 machines like this out of the hundreds of i-models we've installed over the years. I want to say that 2 of the machines developed the problem after install, and the other 3 or 4 were like that right out of the box. I'm also pretty sure that it was only the slower models (36 ppm and under) that we ever had the issue with. I don't remember any of the 45+ ppm machines with the problem, but old age might be messing with my memory also.A Ricoh Service Tech for 7 year. A Konica Minolta Service Tech for 7 years.
