Paper Feed Solenoid Kits

HP RK2-0269 Paper Feed Solenoid Repair Instructions

RK2-0269Paper feed solenoids are the single most
neglected problem hp laser jet printers have.  I have followed technicians who could not figure out why they were having jamming problems but did not even mention the solenoid.  Paper feed solenoids should always be suspect when you begin diagnosing an HP printer that is jamming.

This site includes many articles and how-to videos on testing and replacing  paper feed solenoids .  I believe its an important issue, hence the amount of time and effort i have put into it as you will see if you’ve browsed my website.  I myself repair HP printers and use this information quite often.

In this article and videos, it shows what I believe to be a professional way of repairing these type of hp solenoids that are used in almost all of hp laser jets.  Watch the videos and let me know if you find that to be true.

I am offering the videos free to everyone to use as a “how to” but you must first have a material to replace the old material.  Think about getting the material or the complete repair kit from  me.  “Why?” you ask… Here is my sales pitch.

Sales Pitch
When I began working on HP printers I kept stock of a few different types of new OEM Hewlett Packard Paper Feed Solenoids.  They were and still are not cheap.  I replaced quite a few each month.  I really didn’t want to install used Solenoids.  I’ve had company’s send me used solenoids and they were often worst than the ones I was replacing. In the back of my mind I was thinking it would be great if a company would offer this material or a kit that would replace the pad.  Somehow make a convenient replacement pad so that I wouldn’t have to spend so much time, money and  feeling kind of guilty throwing away a perfectly good solenoid that the only thing wrong with it was a bad pad.

So I set out to find a good replacement material and cut them myself, and I did.   It has taken me some time to do all of this but so worth it.  I created a little kit I can carry and thought how handy it was.  Each kit is pre-cut and the material lasts and has a good sticky back tape to install easily which is what I was looking for.

You should always be prepared and feel good about your fix.  Watch the videos and follow the links.

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.

P4515 Fuser Sleeve Izzy says, "Always purchase quality parts!"

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!

Print or Copy Quality, toner

How to Remove Repetitive Image Defects from an HP Toner Cartridge

Often when removing the toner cartridge for a paper jam,  shaking it to get a few more prints or removing it while performing printer maintenance the toner stirs up and a small bit of toner or even a speck of unknown material will adhere to the charge roller inside the cartridge.  This causes a small dot to appear on all of your prints.  These dots are all “in-line” and have identical spacing.  HP calls this a repetitive image defect.

All HP all-in-one laser printer toner cartridges are affected and this problem can arise.  Once this happens you really have nothing to lose but to try this fix.  It is definitely worth a try as you would have to replace the  cartridge if you didn’t want a dot on all of your documents.   The cost for these cartridges are quite expensive.    If you just purchased the cartridge you can try to have it replaced under warranty.  NOTE:  When removing the toner cartridge for whatever reason, never set the cartridge upside down.  Place it right side up.  Always set it down gently.

How to tell if it is the Charge Roller Causing the Issue
You will know it is caused by the Charge Roller by understanding the image defect ruler.  The spacing on most laser printers will be 37.7mm or 1.5 inches between each dot.

How to Fix It

What you will need
You will need a Q-Tip,  writing pen and a flashlight.
Also you will need a sample of the print job with the image defect.

Shine a flash light into the shutter and locate the dot and clean it with the Q-Tip. WARNING: Do not use and type of chemical , water or solvent as this will destroy the charge roller.
Shine a flash light into the shutter and locate the dot on the charge roller and clean it with the Q-Tip.  WARNING:  Do not use any type of chemical , water or solvent as this will destroy the charge roller.

Next re-install the toner cartridge and print a configuration page.  If the dot is still there, redo the previous steps until the dot is gone.  Have patience.  It sometimes takes several tries to get rid of the dot.  I have had a 100% success rate, so don’t give up.  Following is a list of directions to print a configuration.  You can google the directions if you do not have a service manual for your particular machine.

Firmware

HP M602 Pre-Boot Walk-Up Method (USB) Firmware Install

Thumb Drive Firmware install
Thumb Drive Firmware install

This article shows how to upgrade the firmware on an HP Laser Jet 600, M601, M602 and M603 Series Printers.  We will also show you why you may or may not need to upgrade  the firmware in the first place.

“When do I need to upgrade the firmware? “
You might ask.  Upgrading the firmware can correct problems and also add new features to devices without replacing hardware. It depends on the printer and your printers issue.  One of the biggest and most important problems firmware fixes is the 49 error.  As computers progress many times the printers don’t.  The 49 errors are the printers way of telling you there is a communication malfunction. The printer/computer are speaking a different language and can’t understand one another.  There are many other issues that different models have that a firmware update addresses.  I have the list of fixes from HP for the M602 series at the end of this article.

Batch Loading Firmware
If you have a large fleet of laser printers, you do not want to up-grade your whole fleet all at the same time.
The ability to upgrade firmware on multiple devices “simultaneously” is available with “Web Jetadmin” a free application for managing HP printers.  This “batch” process of upgrading your fleets firmware has the well meaning intention of saving you time, but it is possible you could have some failures and that’s not good.  I would definitely do some testing before the actual process and verify the best practices and procedures on test machines.

Thumb Drive Firmware install
Thumb Drive Firmware install

Here is an example of why you may want to reconsider broadcasting firmware.  On the HP LaserJet P4515 series printer,  using HP’s easy firmware upgrade utility .  If you leave the optional 500 sheet tray(s) on the printer when you send the files, it will brick the tray and the formatter.  To this day I haven’t seen where HP has fixed this.

This is just one example.  My point is, test and verify everything.  I only upgrade the firmware on a unit if it is having a problem that only firmware can fix.    If it’s not broke, don’t fix it. I determine if a printer needs a firmware upgrade on a one on one basis.  Don’t just go willy nilly and start sending global firmware updates!

Future Smart
Hewlett Packard’s new way of upgrading the firmware in their LaserJet enterprise printers and MFPs is “FutureSmart”.  Future Smart firmware is similar to an operating system .  It enables your LaserJet enterprise devices to be upgraded over time, similar to a PC’s operating system with service packs or upgrades.

Service Pack Updates – Source: Hewlett Packard
These maintenance upgrades allow customers to maintain feature stability for their fleet. Service pack updates do not affect existing device features, such as control panel layout and options, while providing important security and regulatory updates or operation fixes. New service pack updates are available multiple times throughout the year.

Major release upgrades
These upgrades allow customers to upgrade their compatible HP FutureSmart devices with the latest features and changes to device functionality. A new major release is easily identifiable with the release number directly following the “HP FutureSmart” name
(for example, HP FutureSmart 3.0).  Major release upgrades are made available to current HP devices when the next generation of HP FutureSmart features is introduced.

How to Remove Stripped Screws on HP Printers

Stripped screw
Stripped screw

Stripped screws are just one  issue a printer technician has to deal with.   The reason screws become stripped are as follows.

  • Worn Screwdriver Tip
    Yes, a screwdriver tip can wear out.  The sides get rounded and don’t fit as snug as it should and will  slip off the screw and round the screw head stripping the screw.

Using the Wrong Size or Type Driver
Working on Hewlett Packard printers the screwdriver of choice would be a Type Number 2 Phillips  Screwdriver.  I worked for years and was oblivious as to what size and type of screw driver I was using.

  •   Some copiers use Japanese type screws.   To more easily tell the differance between the two there should be a small dot or tiny hole on the edge of the JIS type.   Here are the differences of JIS (Japanese Industrial Standard ) and Phillips.
  • US phillips

    JIS

  • Not Applying Enough Pressure
    If a screw has never been removed, they are locked in very tight.  Not applying enough pressure will round the screw heads and strip the screw.

Removing the Stripped Screw
You will need a regular blade screwdriver preferably one that you don’t care about  and a ball-peen hammer.  Any hammer will do, but a smaller size will be easier to work with.

NOTE:  To remove most screws you will need to drive them “Counter Clockwise”.

Counter Clockwise
counter clockwise

 

1. Take the driver and hold it straight on the edge of the screw.  You need to hit the screw with the screwdriver blade enough to cut a notch in the edge of the screw .  This notch will help keep the  blade from just sliding off for the next step.

Create a notch in the edge of the screw

2. Place the blade at an angle that will drive the screw in a counter clockwise direction in the notch of the screw you created in the previous step.

hold the blade at an angle that will drive the screw in the counter clockwise direction.
hold the blade at an angle that will drive the screw in the counter clockwise direction.

3. Hit the screwdriver until you notice the screw break free.  Replace the stripped screw with a new screw and you are done.

I believe there could be an instance where the screw is in such a place or angle that you cannot get the edge of the screwdriver where you can use this method.  I have been lucky because I have always been able to get the screw out.  There are other methods such as drilling, using a dremmal, but for printers or copiers this method should take care of it.  If you have a story or experience with removing or not  being able to remove a stripped screw, please let us hear about it.
