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”.

Rebuilding Optional 500 Sheet Paper Feeder P/N Q2440B for the Hewlett Packard 4200, 4300 4240, 4250 and 4350 Printer Series

The Paper feed solenoid at some point will need to be replaced because of Jamming issues. You will experience 13.98, 13.02, 13.03 errors. Look at the error log in diagnostics menu. I test the solenoid by using the paper path test and run 10 single sided prints and pay attention to the timing of the prints coming out. If the solenoid is bad you will notice it begin to pause or I liken it to burping. If it’s real bad it will just jam and you will get the errors listed. Some of you will opt to buy a new unit from EBAY but I’ll warn you that buying a used one leaves you with the same problem. I recommend buying a new one or rebuilding your existing unit.

How to Fix 13.02, 13.03 and 13.98 Error Codes on HP Laser Printers

If your HP Laser printer is frequently Jamming, take a look in the Error Log.  If you see these errors you more than likely have a bad paper feed solenoid.  If you have more than one tray having jamming issues, the paper feed solenoid could be bad in that assembly also.

This article is really about Hewlett Packard’s Infamous Feed Solenoids. There are many part numbers for the same part, but most Hewlett Packard Laser Printers use a paper feed solenoid similar to part number RK2-0269.  This Part number is technically for the LaserJet 4200/4300/4250/4350 series printer, but will work in many others. The problem with these is that the material that HP chose is CRAP! Time and usage makes the foam on the solenoid plunger plate stick. The material loses is sponginess and becomes like glue. This causes the Solenoid to stick as it feeds and the feed roller will push an extra sheet of paper  into the machine. ( Sensors  know that this is wrong) and thus causing the errors to occur. Errors 13.02, 13.03 and 13.98. If I see these ERRORS when I print and Review the Error Log, I know That RK2-0269 is causing the issue.  I have videos on replacing the solenoids just go to my video page and look for what you need.

HP LaserJet 4250 Replacing Tray 2 Paper Feed Solenoid for 13.02 Jams

Installing these is fairly easy for anyone with mechanical aptitude and a Phillips number two screwdriver.
Note:It is not necessary to remove the Fuser Assembly or the Toner Cartridge.

Step 1.) Begin by removing all Optional Equipment.
Step 2.) Paper Tray 2
Step 3.) Remove Tray 2 extension door /Paper Tray Dust Cover.
a.) Carefully flex the Tray 2 extension door to release the hinge pin near the power cord side of the product.
b.) Rotate the Tray 2 extension door to the horizontal position, and then pull up on the keyed hinge pin to release the door.
Step 4.) Swing open the rear output bin.
Step 5.) Remove the top-accessory cover if stacker is not installed. Lift the top-accessory cover up and off the product.
Step 6.) Remove Formatter Assembly.
Remove 2 screws or 2 thumb screws and grasp the formatter cage and then slide it away from the machine to remove it.
NOTE: When you reinstall the formatter cage, open the formatter-cage door before you fully seat the formatter cage, and verify that the formatter PCA connector is aligned with the connector on the product chassis.
Step 8.) Remove the Top cover
a.) 4 screws… 2 under the top-accessory cover and 2 under the toner cartridge cover.
b.) Use needle-nose pliers to release the print-cartridge drive-arm tab

CAUTION: The accessory pin (located in the left-rear corner of the cover) is not captive.  Grasp the rear side of the cover and the lid of the cover then lift up and off of the machine. Make sure that the Toner Cartridge Drive Arm is down (Engaged) so that it is out of the way.

Step 9.) Remove the Right Side Cover.
NOTE: When reinstalling the cover make sure that the power switch connecting Rod goes in between the on/off switch Lever guide inside the cover.

Step 10.) Swing the power switch lever out of the way
