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”.

3 Must Do Repairs on HP Laser Printers

These 3 little items can cause huge problems.  They are the cause of jamming, registration skew,  13.98, 13.02, 13.03, 13.05, 13.06 error codes and they will also cause other issues that will leave you scratching your head.  If, while your doing a maintenance or general cleaning, do yourself a favor and add this to your list of preventative maintenance.

#1.) Inspect the Paper Full Sensor Flags Located on the Delivery Assembly.

Test the levers by pushing down on the levers and pull back on them.  You’ll will feel it sticking if the foam is deteriorated.
See video below.

Removing foam.
Remove the Top Cover.
Turn the cover upside down and remove 2 screws and the grounding plate.
If the foam has become deteriorated, scrape the old foam off of the Paper Full sensor flag assembly, and remove leftover foam and glue with alcohol.
There are two locations on the assembly for you to remove foam from.
See pictures below.

NOTE: It is not necessary to reinstall new foam.

Exit sensor flags

#2.) Inspect Registration Shutter on the Registration Assembly.

Remove the toner cartridge and pull/push on the Registration Shutter so that it is all the way open and see if it is sticking.
See pictures/video below.
If the foam has become deteriorated simply remove it by scraping it off with a knife and then remove leftover foam and glue with alcohol.
NOTE: It is not necessary to reinstall new foam.

3 Must Do Repairs on HP Laser Printers

These 3 little items can cause huge problems.  They are the cause of jamming, registration skew,  13.98, 13.02, 13.03, 13.05, 13.06 error codes and they will also cause other issues that will leave you scratching your head.  If, while your doing a maintenance or general cleaning, do yourself a favor and add this to your list of preventative maintenance.

#1.) Inspect the Paper Full Sensor Flags Located on the Delivery Assembly.

Test the levers by pushing down on the levers and pull back on them.  You’ll will feel it sticking if the foam is deteriorated.
See video below.

Removing the Foam.
Remove the Top Cover.
Turn the cover upside down and remove 2 screws and the grounding plate.
If the foam has become deteriorated, scrape the old foam off of the Paper Full sensor flag assembly, and remove leftover foam and glue with alcohol.
There are two locations on the assembly for you to remove foam from.
See pictures below.

NOTE: It is not necessary to reinstall new foam.

Exit sensor flags

#2.) Inspect Registration Shutter on the Registration Assembly.
Remove the toner cartridge and pull/push on the Registration Shutter so that it is all the way open and see if it is sticking.
See pictures/video below.
If the foam has become deteriorated simply remove it by scraping it off with a knife and then remove leftover foam and glue with alcohol.
NOTE: It is not necessary to reinstall new foam.

#3.) Inspecting Paper Feed Solenoid Dampener Arm for deteriorated Foam.
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.  Models Hewlett Packard Laser Jets 4200, 4300, 4240, 4250, 4350, P4014, P4015, P4515 and 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.

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.

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.

→13.02←

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.

The following are videos on diagnosing and replacing the paper feed solenoids.
