Fuser Drive Gears (Swing Plate) P4515 series; Change for Improved Yield and Sustainability

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.

Testing Paper Feed Solenoids.

Many people who repair their own HP printers change the feed rollers and continue getting jams and decide to call it quits at that point.  They cant understand why it’s still jamming.   The problem more than likely is the Paper Feed Solenoids.  Look in the event log.  You will see 13.98, 13.02, 13.03 errors if the solenoids are having issues.

It’s a hassle to have to pull all the covers off just to see if the paper feed solenoid needs to be replaced.  Here’s a way to test them so you don’t have to.  This test applies to  Hewlett Packard Laser Jets 4200, 4300, 4240, 4250, 4350, P4014,  P4015,  P4515 and many others.

Go into “Diagnostics” and “Paper Path” Test Mode.
Set it for 10 prints, single sided and select the tray that you would like to test.
Pay close attention  to the sound, speed and rhythm of the machines operation.
If the solenoid is good you will hear the same rhythm and operation through out the test.  But,  if there is an issue with the solenoid you will notice a pause.   It will “hiccup” and pause just for a moment, then continue.  If it is really bad, it may end up jamming or become obvious that the foam is totally destroyed.
You will become acquainted with this and be able to quickly tell if there is a problem.  If you don’t do it that often you may have to pull the solenoids off to test them.  It’s very subtle but if you do it enough you’ll be able to spot it right off.

Look at the following Video below. I am testing tray 2 and tray 3 on a Hewlett Packard Laser Jet 4250.  First is tray 2 with no problem ( Just Changed it) and next is tray 3 with an obvious problem with the solenoid.

Remove the Solenoid and do a visual inspection.

See Video Below

Replaced the bad solenoid with a “New Solenoid  RK2-0269”.
