Reducing Noise on the HP P4515 Series Printer

The P4014, P4015 and the P4515 are an extremely loud piece of equipment.  The main location of the noise emanates from the fuser drive area.  The dB Level specifications for the Laser Jet P4515 (while printing)  is at 74 dB.  The predecessors noise level specs puts the  Laser Jet 4250’s  dB level at 69 dB.  Quite a bit of difference.  If you are using re-manufactured fusers or the fuser drive gears are worn I would put it much higher.   The most probable reason for the refurbished fuser creating so much more noise is the lack of lubrication and/or inferior high temperature grease used on the heat sleeve and heating element.

Inspecting the Fuser Drive Gears
The first thing to look at and the  easiest is to pull out the fuser unit and inspect the area below the drive gear.

 You will see a pile of white powder or dust from gear wear in the shape of a small pyramid or volcano.
You will see a pile of white powder or dust from gear wear in the shape of a small pyramid or volcano roughly in the location outlined.

To get a more accurate assessment of gear wear, you can use a small flat blade screwdriver and slide it along the gear teeth.  On the inside of the drive gear against the frame the the gears do not make much contact so it is like new on that side.  When you slide your driver across the gear it will stop your screwdriver because of the difference in height.

A Swing Plate or Not a Swing Plate, That is the Question
I call the P4515 fuser drive gears a swing plate.  Saaaaawwwwwrrrrrry!  Technically it is stationary,  unlike the Laser Jet 4250 series.   For me,  it just makes sense…right?   Question: If I’m on the phone describing it to you and I tell you it’s the  “Swing Plate” you know exactly what and where I’m talking about don’t you?

 

Quiet Mode
One final mention.  If speed isn’t an issue, they made a firmware enhancement.  With this revision of firmware 20080908 04.046.2 and all revisions after has, “Quiet Mode”.

You can go to “configure device” and in settings you can select this “Mode”.  It really does reduce the noise!  Only thing is… it also reduces the speed!

 

Three Possible Solutions to Reduce Printer Noise.

To reduce the noise on the P4515 series printer there are three items to look at and possibly repair or replace.

#1.) The fuser assembly,  part number RM1-4554.  You could also clean the heating element and re-apply high temperature grease.

#2.) The swing Plate,  part number RC2-2432.  See my post on
HP P4515 Fuser Drive Gears (Swing Plate) ; Change for Improved Yield

#3.) Choose “Quiet Mode”  What a sorry excuse for a printer tech!

59.40, 59.50 and 59.60 errors on the HP LaserJet P4515 printer

59.40, 59.50 and 59.60 Error “Theory”

This article is an attempt to understand the cause and theory behind the 59.40, 59.50 and 59.60 errors in the LaserJet P4010 and P4510 Series printers, and the other problems they cause.  Simply put, there is an issue of hesitation or drag in the rotation of the drum drive motor (M102).

The following information comes from the Hewlett Packard LaserJet P4010 and P4510 Series, Service Manual, Page 287 in “Control-panel messages

Control panel message                    Description                           

59.XY ERROR                              A temporary printing error occurred.

For help press? Alternates with 59.XY ERROR, to continue turn off then on.

Recommended action
 Inspect the DC controller PCA and verify that the following connectors are firmly seated.

◦ Drum motor (M102) to connector J87

◦ Feed motor (M101) to connector J91

◦ Fusing motor (M299) to connector J89

NOTE:
There is a cable between the drum motor and the DC controller. Both Ends of the cable need to be firmly seated.
If the error persists, from the DIAGNOSTICS menu, run the component tests for each motor to verify that they are  operating. If any of the motors is not operating, replace the motor.

What does the XY mean after the 59?
X is telling you which motor is having the problem.
Y tells you which color it is.  0 = Black
(M102) Drum Drive Motor is a 24 DC volt brushless motor P/N – RL1-1659


What is the problem?
More than likely you will encounter this error with a refurbished toner cartridge. The problem is that the drum blade that cleans the photoconductor is either…

  1. Defective
  2. Does not have the proper drum (photoconductor) lubrication.

CC364A Black, Standard Toner Cartridge               Yield 10,000 pages Approximate

Blade

The solution to all of this is just to replace the toner cartridge.  So why did I spend so  much time on this issue?  In addition to replacing the cartridge it can also damage the drive gears.  That would mean an expensive repair caused by a incorrectly refurbished toner cartridge.  When these gears strip you will hear a high pitched whinning sound and get paper jams under the toner cartridge because the drum assists the paper as it goes through the machine.

The Repair
You will need to replace the drum drive assembly P/N RC2‑2484 and also the drum drive motor P/N RL1-1659

Drum Blades
The drum blades are normally made of urethane.  A strong rubber type of material.  You can liken a drum blade to a windshield wiper.  And just like your wipers they start to streak when they are worn.  You will also get drum blade chatter if not properly lubricated.  If you do not have the proper lubrication it can also flip and damage the drum.  On this type of photoconductor the lubrication most widely used would be Kynar Powder.  Using toner also is acceptable but builders like the Kynar because its not as messy and the residual will remain longer, thus preventing drum blade problems.  This prevents the blade from dragging or locking up or even flipping.  I made some quick videos of manually turning the drum on a defective cartridge after a 59 error and one of a newly opened cartridge and the difference is amazing.  It was definitely much more difficult to turn compared to the new cartridge.

What the Drum Drive Motor does.
The drum drive motor drives the components inside of the toner cartridge.  The following are some of the components that are being driven by the drum drive motor.

*Photoconductor
*Developer or Magnetic roller
*Primary charge roller (PCR)
*Various drive gears

The idea behind purchasing refurbished toner cartridges is saving money, well maybe even the recycling aspect but when they start causing damage to the printer you may want to rethink using them in this model.

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.

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.
