Error Codes

60.X errors in HP LaserJet 4250 Series Printer

A 60 .X error means that the machine is experiencing a problem with the paper tray lift motor.  Here is the description and the recommended action HP gives for the 60.X error.

60.2 printer error
The tray 2 lifter-motor is not functioning.
1 Turn the printer off and then on.
2 If the error persists, turn the printer off.
3 Verify that the tray 2 lifter wire-harness is full seated in its connector on the dc controller PCA (location J93).
4 Replace the tray 2 lifter-driver assembly. See Tray 2 lifter-drive assembly.
5 Replace the dc controller PCA. See Dc controller PCA.

Notice that the error 60.X in where X=The specific tray having the problem.
60.2 = tray 2
60.3 = tray 3
60.4 = tray 4

In my experience I have never replaced a dc controller or a tray lift motor for this error code.  I’m sure that there have been cases of this but doesn’t happen very often.  The more popular issue has been a broken paper tray.

Tray Length Guide-RM1-1088
Paper Tray Length Guide

The rear length guide will break and that causes the lift mechanism on the tray to bind and stop the lift motor and it will throw the code.

Next, if that isn’t the problem you will need to look at the tray lift  motor tension spring.  These break and will cause the 60.X errors also. see illustration

Lift Motor/Tension Spring

It’s always nice to have an extra spring in your goody box, but we all know that’s would be to good to actually happen.  Most of the time I can find the broken spring inside the machine or the customer found it and saved it.  Just reform the spring and viola your back in business!

That’s it!  This isn’t too difficult of a problem to fix you just have to know where to look.  I will have a repair video for this very soon.  Keep and eye out for it.

WTF Does “Misprint” Mean?

What is a “misprint”?    It’s another term Hewlett Packard has come up with to describe a paper jam in their laser printers.  The new error code associated with it is 13.0000.   The earlier version of this would be 13.01 .  The confusion comes from people not knowing what a misprint is.  We are  so used to using the term “paper jam” or “mis-feed”  that we believe it has to be a serious problem and we ” overplay this “misprint” thing… help!

Here are the definitions for the term misprint.

mis·print

Mis`print´   Pronunciation: mĭs`prĭnt´
noun: misprint; plural noun: misprints
misprint – a mistake in printed matter resulting from mechanical failures of some kind ;  misprint – print incorrectly
source WordNet Dictionary


Hewlett Packard Description of a Misprint
Source – HP pro 400 m451dn printer service guide

Misprint Press [OK]
Description
Paper has been delayed as it moves through the product.
Recommended action
Press the OK button to clear the message.
To avoid this problem, try the following solutions:
1. Adjust the paper guides in the tray. Make sure the front paper guide is pushing the paper against the back edge of the tray.
2. Use paper that meets HP specifications. Store paper unopened in its original packaging.
3. Use the product in an area that meets the environmental specifications for this product.

In the newer color laser printers “Misprint” is used to differentiate between a regular paper jam and a paper jam that is not sent within the correct timing of the machine.  Here’s what happens step by step in a color printer with misprint problems.

At the beginning of a print job the information is sent from the computer to the printer.  The image has already been created on the ITB (Intermediate Transfer Belt) ahead of time . The full image is laid onto the ITB with each color of toner used in the document.  The paper did not feed correctly and  in this situation the paper never makes it to the registration sensor.  Everything in a printer is precisely timed, so the toner is about to be wasted and sent to the waste toner bin.  Now, because that image is unusable the machine begins to clean the ITB which is the “Cleaning Mode”. Then after all this is over the machine will give the message of  “Misprint”.This terminology is not limited to just color machines it also is used in Black and white or monochrome printers.  Again, the description is the same “Paper has been delayed as it moves through the product”.  So there you go, “Misprint” just means that you have a paper jam, so you can relax and remove your paper jam without any stress at all.

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.

Q2440B

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.

Service

Managed Print Services

Managed Print Services or Total Cost Management,
There is an explosion of service companies providing this way of tracking all of the costs associated with your copiers and printers. It is called “Total Cost Management.” Most if not all copiers, MFP’s and printers can be monitored on your network with revolutionary print management software. You are able to track your total pages or copies. You can monitor toner low warnings, error codes, paper jams, and everything associated with your machine. This software can help you calculate how much you are paying for the total ownership of all of your equipment. This is very helpful when purchasing new equipment. The software will help you figure all the costs of your equipment, toner, parts, supplies and service.If you are shopping for a Managed Print Solution,  this article deals with the ins and the outs of MPS, read on…

Laser printer maintenance contracts are similar to copier service contracts. Most laser printer service contracts are billed by cost per print.  MPS takes it another step and will be responsible for an entire fleet of printers, fax machines and copiers. Each time you print a page the internal meter clicks.  MPS normally has a software package that tracks page counts, order toner automatically, flag a printer for service if an error pops up and invoicing and many other things.  A big advantage  to MPS  is tracking of individual hardware.  Say a piece of equipment is under utilized or over utilized you can rearrange locations to suit your needs and become more effective by deploying the correct equipment in a specific location.  Tracking specific costs for supplies is another huge benefit.

Basically,  after the end of each month or quarter an invoice is generated by multiplying the cost per page by the total prints made. The cost per page is determined by monthly volume, age of machine and environment. Environment plays a big part because if it is in a dirty environment it will need possibly twice as much service than a machine in a clean environment.   The good part is that your costs are fixed, so you will know how much per year you will spend instead of hoping it won’t break down too much or have a serious or really expensive part break. There are many ways of paying for a service contract. It depends on the way you and your company would like to be billed. Most service companies offer monthly, quarterly and annual billing.

Coverage
Understanding what is covered and what is not covered is very important to find out before you purchase a service contract. Does the contract include supplies? Some supply items are toner and maintenance kits. Find out what hours the service company is available and days of the week that they operate. Which holidays do they take off? What is their response time? Most service contracts do not cover abuse or neglect. So be cautious with those paper clips and staples as they can cause an expensive repair and it probably won’t be covered. Get all of this in writing then there will not be any surprises.

 

Quality Issues

Solving Image Problems on HP Laser Printers

There are several image related problems that can occur. If you want to save money and repair it yourself this article is for you. Read about the most common image related problems that HP Laser Printers have and how to resolve them.

Here are a few examples of image related problems:

Blank, Solid Black, Streaks, Double Images, Specks, Lines, Light Print, Dark Print, Blurred Image, Flaking / Rubs off

Cartridges: Most of these problems are related to the toner cartridge. If you don’t have another cartridge to test it you can diagnose the problem another way. Put a sheet of paper in tray 1. Run a configuration page with your hand on the power switch. When the page reaches midway, turn the power off. You may have to do this a couple more times to get the timing correct. Now that you have stopped the paper midway, carefully remove the cartridge and the paper from the machine. Inspect it to see if the problem exists before it reached the fuser. If it does then it is in the cartridge, or possibly it could be in the Laser or scanner assembly. If it does not, then you have a bad fuser assembly. Remove the fuser and inspect it.

Cartridge problems are the most common cause of image related problems. I find more problems with remanufactured cartridges because the manufacturer is not replacing certain major components that cause the defects. Make sure they replace the drum. Also, look for companies that are ISO 9002/14001 certified and STMC certified. This will help weed out the undesirable cartridges. To be honest, I have seen a lot of OEM cartridges fail. Cartridges fail for several reasons, such as foreign objects getting up into the cartridge causing lines, streaks and leaking. This can be resolved by being careful not to remove staple or paper clips in and around machine. You should also have your machine cleaned. Vacuuming all of the paper and toner dust can help decrease this. Remember to only use a service vacuum that can handle the tiny particle size of toner.
Printing a Configuration page: You will always need to print a configuration page, and here are some reasons.

Image quality test, Page count, Serial number of machine, Configuration of printer, The last few errors, Jet Direct print server card is installed, Many others…

Here are a few directions on how to print out a configuration page.
If you don’t see your model scroll through the menu on your printer and it should be easy to find.

HP LJ-4000/4050/4100
1 Press [Menu] until INFORMATION MENU appears.
2 Press [Item] until PRINT CONFIGURATION appears.
3 Press [Select] to print the Configuration Page.

HP LJ-4200/4250/4300/4350
1 Press (SELECT button) or the MENU button to open the menus.
2 Use (UP ARROW button) or (DOWN ARROW button) to scroll to INFORMATION, and then press the Check button (Select)
3 Use or to scroll to PRINT CONFIGURATION, and then press the check button.

HP LJ-8000/8100/8150
1 Press MENU until INFORMATION MENU appears.
2 Press ITEM until PRINT CONFIGURATION appears.
3 Press SELECT to print the configuration pages.

Image problems caused by the Fuser Assembly: Symptoms are, toner not fusing, streaking, double imaging.

Note: The 4200 series had a problem with the film getting ripped. You will see strands of plastic pieces coming out of the exit area. It will cause as an image defect, streaking and double imaging.

Diagnose: You can diagnose it by running a configuration page. Rub on the print. Is it flakey? Does the print rub off easy? If it does, it is probably the fuser. Remove and inspect it. You can inspect the film or roller. If you see any damage replacement is necessary.

Note: Most fusers on HP Laser Printers are very easy to remove. If you need instructions on how to remove and install them, I have maintenance kit installation procedures on my website on the front page. Look under customer menus.

Solution – The fuser is replaced as an assembly. Remove and replace Fuser Assembly
WARNING! Let the Fuser Assembly cool before disassembly.

Regarding Light Prints:
If you have replaced your cartridge and you still have light prints or if you have light print over the entire page, you may have economy mode on. Go to quality menu and turn off. I would also try the transfer roller. This is also easy to replace, look in Maintenance kit installation procedure.

One last thing: If you have tried all of the above, there could be another problem. This procedure can be difficult for the average person to repair. It is cleaning the scanner or laser unit. If you are in a very dusty environment the mirror inside this assembly may be dirty. When the mirrors accumulate dust on them the image defect is light prints. I go into detail on cleaning the HP LJ-4000 scanner on another article I have. If you would like, you can go to my website in my article section and check it out.

I hope this article has helped you save some of your hard earned money. There really is no reason to spend money when you can just clean it yourself!
