This is an update to:
HP LaserJet P4015 – Not Picking Up Paper
HP now recognise this as a manufacturing fault and have released a service note for it and will send you a new fuser free of charge. The description of the fault is:
When a print job is sent to the printer, the printer will display processing job on the control panel, and will continually ramp up and down attempting to print the job. After several minutes the printer will return to ready without posting any error messages. Occasionally, after several minutes the print job will print.
The fix for the fault is:
The fuser needs to be replaced and firmware needs to be upgraded to version 04.060.7 or higher.
The customer will need to download the latest firmware from hp.com, version 4.060.7 or higher. The firmware can be downloaded from hp at www.hp.com/go/support . Select Download drivers and software (and firmware) in step 1 and in step 2 type in the printer name, LJ P4014, LJ P4015 or LJ P4515
It’s probably best to update the firmware before you phone HP to report the fault, or at least tell them you have. If you do update the firmware, you will notice some extra numbers and letters on the display when the printer initialises. This is normal, it’s probably used by HP staff for diagnosis.
The fuser is a customer replaceable part, and does not require a service technician to install. If the customer requests a service technician to install the fuser the customer will be responsible for the labor. The fuser can be sent directly to the customer with instructions to upgrade their firmware.
What this means is that HP will send you a new fuser to fit yourself.
The models covered by this service note are:
HP LaserJet P4014 Printer series, HP LaserJet P4015 Printer series, HP LaserJet P4510 Printer series.
EFFECTIVE DATES
Start: 2010-01-01
Expiration: 2010-12-31
What this means, is that HP will send you a new fuser for this fault until the end of 2010, although they do sometimes extend the active time period for service notes.
Very faint print, or blank pages, on a HP LaserJet 4200/4300/4250/4350 can be caused by the toner cartridge earth contact on the left hand side of the printer frame coming out of place. You might also notice that the toner cartridge doesn’t seem to sit properly in the printer.
If you look at the left hand side of the toner cartridge, you should see a metal shaft about 10mm in diameter and 5mm long. As you push the toner cartridge into the printer, this metal shaft slides under a spring loaded metal contact.
The earth contact is L shaped and measures about 40mm x 20mm with a kink in it’s short side. If this contact is resting against the white plastic block on the side frame, it has come out of place.
To replace the contact, use a metal hook, or something similar, and pull it away from the white plastic block. Swing it upwards so that it is upright and fit it into the slot. It should then slide down the slot until it reaches the end. When in it’s correct position, it sits at an angle of about 45 degrees.
If it’s fitted correctly, the metal shaft on the toner cartridge should slide under it. The print quality should now be normal.
If your Hewlett Packard LaserJet P3005 suffers from the worn fuser bush problem described in this post HP LaserJet P3005 – Noisy, Grinding, Clicking, Rumbling , HP will send out an engineer and repair it free of charge if the printer has printed less than 150,000 pages.
The symptoms are a loud clicking or ratchet type noise when the printer is running. Remove the fuser and inspect the green plastic bush on the gear end of the fuser.
Push upwards on the gear on the end of the pressure roller. Pushing against the pressure of the spring, there should be no, or very little movement. Movement shows that this bush is worn.
Contact HP and go through the warranty process. They will ask you the model number and serial number. They will probably tell you the printer is out of warranty. Insist that the printer has a known fault that is covered by a HP service note.
As part of the diagnosis procedure, they will ask you if the printer still makes the noise with the rear door open. The answer is “yes”. HP will then send an engineer out with a fuser kit (fuser and 20 tooth gear) and fit it free of charge.
This error occurred on a long print run after 100-200 pages. The printer stopped mid print with the Attention light, Ready light, and Go lights all on indicating a service error.
If the printer has a service error (Attention light, Ready light, and Go light are on), press and hold (GO) and (CANCEL JOB) simultaneously to see the secondary error message.
Doing this, the Attention and Ready lights were on. This secondary fault code wasn’t in the service manual. Although the Hewlett Packard Color LaserJet 2550 sevice manual lists this as a carousel error.
Turning the printer off and back on resulted in it trying to initialise with a lot of clunking noises coming from the carousel and the error coming up again. With the top off and the lid switch defeated, the carousel was seen to judder forwards and backwards.
After the printer was left switched off for a while, it was possible to print a config page by pressing the Go and Cancel buttons. The error log on the config page showed a 54.07.00 error. Again, this error isn’t listed in the service manual.
This fault was caused by the rotary motor assembly, part number RG5-6958-000CN. This is the motor on the rotary drive assembly that turns the carousel around.
To remove the rotary drive assembly:
- Remove the left and right side covers by removing one screw at the bottom of each, pulling the bottom out, and lifting off at the top and front.
- Release two tabs on the interface cover on the back and remove.
- Release two tabs on the rear cover and remove.
- Open the top door, remove the gear on the right hand side, and remove the top door rack. Refit the gear.
- Remove three screws and lift the top cover off.
- Lift off the top output bin cover.
- Remove five screws from the formatter assembly and lift it up and off. Disconnect two cables as you lift it away from the printer.
- Disconnect the three cables from the rotary drive assembly at the DC controller.
- Disconnect the flat ribbon cable from the laser scanner assembly to the DC controller.
- Remove four screws from the top of the rotary drive assembly.
- Looking from the side of the printer, remove the left hand screw from the left hand motor on the rotary drive assembly.
- Lift the rotary drive assembly out of the printer.
The motor you need to replace is the longer one towards the rear of the rotary drive assembly. Remove the two screws, and the motor can be pulled out.
Reassembly is the reverse of this procedure. Take note of the following:
- Fit the the back of the rotary drive assembly into place first.
- Make sure the formatter assembly is hooked into place at the top. If it’s sticking out at the top, the surface mount LEDs and resistors at the top of the formatter board can get knocked off when the right side cover is fitted.
- When you fit the top output bin cover, make sure the two plastic flaps fit over it and are not trapped behind it.
- Make sure the top cover is located properly in the top output bin cover.
- When fitting the side covers, hook them in at the front and top, and then push the bottom in.
- When you fit the right side cover, it might be best to remove the control panel first. When you fit the control panel into the cover, ease the top of the cover away from the printer. This can prevent damaging the surface mount LEDs and resistors at the top of the formatter board.
If you have a Dell 5100cn or 5110cn colour laser printer that is noisy when printing and prints faint black or no black at all, check the black developer and the developer drive assembly.
The noise is not really like a grinding noise, it is just a louder than normal engine noise. If you print a black only page, the noise will become louder and higher pitched because the engine turns faster.
The cause of this problem is the black developer becoming stiff which then wears the gear on the developer drive assembly that drives the black developer.
To remove the developer unit:
- Remove the image drum assembly
- Remove the toner cartridge cover
- Remove the four toner cartridges, being careful not to drop toner into the toner hoppers causing contamination to the different colours
- Remove two screws at the front and release two clips at the back and remove the top cover
- You can now fit the toner cartridges back in place if you want to seal the hoppers and prevent any stray toner getting into them
- Remove the two side covers by removing the screw at the back and releasing the clip at the front of each cover
- Pull out the two hinge pins and remove the imaging drum cover
- Remove the high voltage power supply board by removing five screws and releasing the plastic clips on the right hand side. Disconnect the two cables at the top of the board. As you pull the board toward you, disconnect the cable plug on the other side of it. When you fit the board back in to the printer, don’t forget to reconnect this plug. Also, make sure the plastic clips are clipped over the board
- Disconnect the four tubes from the back of the developer units by pressing the latches in and pulling them out. These tubes have sealing mechanisms on them but it’s probably a good idea to try and tape them, facing up, to the top of the printer because they will drop toner
- Disconnect one connector at the top of the developer frame and then grab the handle and pull it up and out of the printer. You will need to keep the developer frame level or toner will drop out of the back of the developer units
Once the developer frame is on the bench, you can remove the black developer unit by pulling the two white plastic clips up and the developer can be pulled out. If you tilt the developer up, toner will pour out of the back of it.
Grasp the gear on the right hand side of the developer and see how much force is required to turn it. Compare it to the other developers. You might find it is tighter.
To remove the developer drive assembly:
- Remove the four cable clamps and remove the cables from the cable guide
- Remove two screws and remove the cable guide from the printer
- Disconnect the one connector on the developer drive motor
- Remove three screws and pull the developer drive assembly out of the printer. As you remove it, note the position of the door switch at the top which will probably drop out
With the developer drive assembly on the bench, find the gear that turns the black developer. Run your finger nail up it and you will probably feel a ridge where the teeth are worn. You might also see some white dust from the gear on both sides of the main frame where the drive unit mounts to.
Now would be a good time to remove all the loose toner that’s lying in the printer using a laser vac.
The part number for the black developer is M6091. I’ve had some new developer units that are completely empty and after numerous developer cleaning cycles and printing many pages either won’t put any toner on the paper or dump toner all over the paper.
A genuine developer unit from Dell will already have some toner in it and will have two sealing plugs in the back of it. Remove these two plugs before you fit it. You will find that these work first time without any problems.
The part number for the developer drive assembly is H6702.
After reassembling the printer with the new parts, the printer should be a lot quieter and the black will be printint normally again.
The Hewlett Packard LaserJet P3005 commonly suffers from noises from the back of the printer. These can range from a rhythmic rumbling noise to a loud grinding or clicking noise. It’s caused by either the fuser or the fuser drive gears.
UPDATE
If your LaserJet P3005 is suffering from the worn fuser bush problem, HP will now replace the fuser free of charge if the printer has printed less than 150,000 pages.
See this update:
HP LaserJet P3005 – Noisy, Grinding, Clicking – Update
Removing the fuser and drive gears for inspection is fairly easy:
- Open the rear door and pull it open past it’s stops
- Remove two screws
- Open, or remove, the paper tray
- Open the flap at the bottom of the rear cover, release the two clips at the bottom and pull the rear cover out
- Remove the I/O cover (rear left hand cover)
- Unplug the cable on the left hand side of the fuser from the power supply and remove it from the cable clip
- Unplug the two cables coming from the right hand side ofthe fuser and release one cable clip
- Release the two clips on the duplex inlet guide (black plastic guide) and slide it out of the back of the printer
- Remove four screws and pull the fuser out
- Look inside the left hand side of the printer and you will see four gears
- Unclip the top gear at the back of the printer and the gear below it will slide off
- Remove the plastic clip holding the upper gear further forward in place and slide off this gear and the one below it
Remember how these gears go back onto the printer. When you refit the back cover, fit the top into place first.
Inspect the teeth of the four gears for wear. Sometimes, it’s hard to see, but you might feel a ridge if you slide a small flat blade along the teeth of the gears. If your printer is getting progressively noisier with a rumbling type of sound, it’s probably one or more of these gears worn.
These are the part numbers for the gears, it’s probably best to replace them all in one go:
RU5-0956-000CN, RU5-0957-000CN, RU5-0958-000CN, and RU5-0959-000CN.
Don’t forget to put some grease on the new gears.
There are two things to check on the fuser.
First check the light brown coloured gear. Check the teeth for wear. Also, check the part of this gear that slides over the metal shaft. Turn this gear, it will be tight, and look for a split in the plastic.
Second, check the green plastic bush that the metal shaft rotates in. Push upwards firmly on the gear. If there is excessive movement, the bush is worn. You might also see green powder sitting on the bottom of the fuser. The worn bush will cause a loud clicking noise as the gears are being forced apart as they turn.
The part numbers for the fuser are:
RM1-3740-030CN For 110-127 VAC and RM1-3740-031CN For 220 VAC to 240 VAC.

The most common cause of a 10.92 cartridges not engaged error on a Hewlett Packard Color LaserJet 3000 / 3600 / 3800 is broken cartridge locks on the right hand side of the printer. Another possibilty is the slide lever that operates the cartridge locks is broken.
This is the diagnosis of this error form HP’s service manual:

● Replace the memory-controller PCA if
it is damaged.
● Check the gears on the print-cartridge
drive motors. Replace defective motors.
● Replace the DC controller.
If you follow this procedure, you will end up replacing the DC controller which won’t repair the fault.
What you need to do is slowly open and close the front door. Make sure that the flaps over the front of the print cartridges move. If you look carefully, you should also see the white plastic drives insert into the right hand side of the print cartridges. Also on the right hand side, you should see the levers lock the print cartridges in place.
If you don’t see any of these parts move, the slide lever might be broken. If these parts do move, remove the print cartridges and inspect the plastic levers that lock the cartridges in place on the right side of the printer.
If the cartridge locks are broken, HP will send out an engineer to replace them free of charge, even if the printer is out of warranty. Phone up the warranty support line and tell them the plastic levers that hold the toner cartridges in place are broken. If the printer is out of warranty and they start offering you the paid options, remind them that there’s a service note that covers this fault.
If you decide to do the repair yourself, the part numbers are Q5982-67925 which is a set of four cartridge locks and springs and should include instructions. The part number for the slide lever is RC1-6643-020CN.
Be warned, it isn’t easy to replace the cartridge locks or the slide lever. I’m not going to describe how to do it. Instead I’ve provided links below to download the replacement instructions and the service manual.
The service manual is over 17Mb in size and you will only need it to remove the covers, so only download it if you need it. The replacement instructions are only just over 1Mb and you definately need to download and read this.
Follow the instructions closely and pay particular attention to the location of the screws to remove the main drive unit and the gear alignment when reassembling the printer.

A grinding noise and paper jamming at the fuser in a Hewlett Packard LaserJet 5 is more than likely caused by the drive train gear cluster.
Open the rear door on the printer, remove two screws, and then pull the fuser out. Shine a torch into the back of the printer and look at the condition of the gear that drives the fuser. You might see that some of the teeth on this gear are worn or completely missing.
The part number for the drive train gear cluster is RG5-0876-050CN. Hewlett Packard list this part as discontinued but you might be able to find a supplier that can sell you one.
Before you buy this part, check the condition of the fuser. Check the gears and the surace of the heater roller. If the fuser is worn as well, you will need to price this up as well. Bearing in mind that this printer is now over ten years old and probably in need of a complete clean and service , it might be time to buy a new model.
If you decide to replace the part, this is what’s involved:
- Remove the fuser as previously described
- Undo one screw at the back of the right side cover and slide the cover off
- Undo the screw on the memory cover on the formatter assembly and remove the cover
- Remove four screws on the side and two at the back of the formatter assembly and pull the formatter assembly off
- Remove one cable and four screws from the main motor and then lift the motor away
- Remove two screws and the drive train gear cluster will slide out the back of the printer
Before fitting the new part, check that it is lubricated. If not, apply some grease to the gears. Also, make sure it is seated properly before fitting and tightening the screws.
