Hello colleagues. MX-M754N. There are several such devices in service. Everyone has a similar problem: strong noise when the stove is rotating and rapid wear of the stove drive gears. The drive gears NGERH2359FCZZ, NGERH2206FCZZ, PCLR-0630FCA1, NGERH2059FCZ1 have been repeatedly changed. The noise did not decrease. The gears fail after a while. More than one set of gears has already been replaced. The fuser unit was also restored with the original service kit. Can you tell me what the problem might be?
