HP P4515 Fuser Drive Gears (Swing Plate) ; Change for Improved Yield

Swing Plate Assembly

Hewlett Packard LaserJet Models P4014, P4015, P4515 P/N RC2-2432 M600, M601, M603 P/N RC2-2432-M601

When installing new drive gears, I’m recommending using Swing Plate RC2-2432-M601 (M601) instead of the RC2-2432 (P4515) In P4515, P4015 Series Printers. The main gear on the M601 that butts up against the fuser drive gear is” Helical” but on the P4515 the Fuser drive is a standard “Spur” Gear.

Don’t be worried because it will mesh fine with the P4515 Fuser Gear. The Swing Plates RC2-2432 (P4515) I was installing had a very short life. I have some of these printers that print 40K per Month and I was changing them constantly it seemed.

Directions on replacing the fuser drive gears (Swing Plate) on the HP Laser Jet P4515 Printer


The drive gear noise once installed is quiet and smooth. We know that the P4515 printer series generates a lot of noise. I am getting more than 3 times the life out of them now using the M601 style. I just changed one in a P4515 and it had 350K on it. The reason why I changed that one was because it was noisy and that’s the only reason. Very little wear. When I used the Standard swing plate it would strip at approximately 40 -50K and it would go down or be very noisy. I now have this type installed in all of my high volume areas and it has improved call back and call generation quite a bit.

Helical gears offer a refinement over spur gears. The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle.
