Yet another great series of printers introduced in the 4000 line of printers by HP, these machines are the workhorses that we’ve come to expect from HP for fast every day printing. They experience very few problems and have long life spans. The majority of the problems are easily fixed and at a relatively low cost to the customer making these printers a favorite in any work environment.
In this article, I will discuss a few of the issues related to these machines to help make repairing them as trouble free as possible.
13.01 Paper Jam Error
Not the most common error but it still does occur on these printers. Obviously, the first thing to check is the feed separation rollers (part # RM1-0037) The rollers for the 4200 and 4300 series tend to last a lot longer than original 4000 rollers but they still wear out so check to make sure they still have tread.
I see a lot of third party rollers for this machine that are either oversized or the rubber wears out sooner than the OEM’s so look for rubber debris below or around the cassette roller and check to make sure there is still tread on the rollers. If you think the rollers look like third party rollers your best bet is to just replace them.
While a lot of third party rollers look OK they can cause lots of odd feed problems in printers. Another thing overlooked is the actual pick up roller (Tray 1 part # RL1-0019, Tray 2 & 3 part # RM1-0036) and sep pad (part # RL1-0007) behind the top feed separation roller. Overtime the rollers get a glaze on them. Or, once these machines get about 200,000 prints the pick up roller wears out and needs to be replaced. These rollers aren’t included in the printer maintenance kits (4200 model printer maintenance kit part # Q2429A; 4240, 4250, 4350 models printer maintenance kits part # Q5421-67901; 4300 model part # Q2436-67903).
Also check the paper stop in back of the tray, remove the paper and make sure the stop indicator is lined up with the size indicator on the tray. People like to push these forward too far because they see a gap in the front of the tray. If pushed forward too far it doesn’t allow the paper to lift properly and feed up into the machine.
Remove and reinstall the paper to make sure it is installed properly and that it’s not folded over in front of the tray. If you are still having issues, remove the back dust cover and with a flashlight watch how the pick up assembly is operating.
13.20 Paper Jam Error
Error message 13.20 means that when the printer was turned on or while the printer was trying to initialize one of the sensors was detecting that there was media present. To clear this, remove the toner cartridge and check for an easily removable jam. If none is found then pull the fuser out and check there, as this is the next easiest spot to check.
However, most often the machine has a jam in the front of the machine behind the MP/Tray 1 tray assembly. Remove the toner and cassette, and use half a file folder to push through the cassette area to the top of the machine to remove any paper particles or free up a stuck sensor flag that was caused from a previous jam. Don’t try this from the top to the bottom as you could break the sensor flag.
On these machines, unlike the original 4000 series, the sensor flag is actually on the feed roller assembly.
If you don’t find any paper debris then the sensor flag might be sticking. Before removing the sensor flag observe the spring installation to make reinstallation easier. Remove the flag from the feed roller shaft and wipe down the shaft with alcohol then reinstall the flag and check for proper movement.
60.2 Tray 2 Lift Error
The error means that the tray didn’t properly lift and the paper sensor wasn’t actuated in the allowed amount of time. When this happens, you will typically first hear a loud grinding or popping sound followed by the error message.
This error is usually caused by improper paper installation. When paper is added, the bottom sheet may get folded up between the front of the tray and the paper inside the tray. This causes the tray to bind as it lifts the paper up.
First, remove the paper and reinsert the tray, if it lifts and goes to a paper out message then double check the back paper stop to make sure it is aligned with the letter indicator. Then reinstall the paper and try again. If it fails with the paper out or after reinstalling the paper, then remove the right side cover and check the paper tray lift motor.
On top of the motor is a spring attached to part of the metal frame. The spring can break causing the motor assembly to not properly engage the gear on the tray. Remove the spring, fold up one of the coils where the spring broke and reinstall.
If the spring is attached, then either try a new tray (500 sheet tray part # RM1-1088] or lift motor [part # RM1-1074 for the 4250 or RM1-0033 for the 4200/4300). Both can be bought relatively cheaply and the motor is not that hard to change out.
Another thing I notice is that when the motor lifts the paper, the back of the tray wants to move up. If the back of the tray guides aren’t snug with the guides inside the machine, the back of the tray will lift slightly causing the noise and error. By adding a small spacer to the back right side of the paper tray you can make the tray more snug in the printer eliminating the noise and error. I’ve only seen this situation once and it was only when the tray had more than 300 sheets of paper in it. But it’s something to think about if other tactics don’t resolve the issue.
On the HP Laser Jet 4200 and 4300 series models the printers built with network cards installed or when network cards were installed at a later date usually used the JetDirect 615 EIO card because that was the current model at the time. Unfortunately, these cards had a board issue. Many customers would call and say for some reason the machine one day would no longer work on the network. Sometimes if they turned the machine off and on it would work again, but after a few hours or so the machine would go back to its unworkable state.
If you run into this issue when onsite, print a config page. Typically, if the network card is not working the network config page will not print, thus verifying the card is not working properly. Check the back of the machine, verify that the machine does have the 615 card and if it does, replace it (part # J6057A for the 4200/4300 — in the 4250/4350 the network card is built in). Typically people go with a newer model like the 620 but really any of the 600 series cards will work. I usually go with a refurb 600 or 610 because of how cheap they are.
I really haven’t had too many cartridge issues with OEM toners but I have run into a few third party toner problems. Some companies use about the same size cartridges for the 4200 series and 4250 series machines and the cartridges will fit into both models and work. However, it takes a little force to get them into and out of the machine. So if you run into a machine where the cartridge is hard to remove or install, particularly on the right side of the machine, and they are using a third party cartridge make sure they are using the right cartridge for the model of the machine.
If, after replacing the cartridge, you still have faded print in some areas then you probably will have to remove the top cover and clean out the front laser/scanner mirror. For some reason, in these HP printer models more than others, if you or the customer blows out the machine toner paper dust flies up into the laser/scanner assembly. Be careful when deciding to use canned air to blow the toners out and cover the laser/scanner area to prevent dust or toner from getting up into the assembly.
49. XXXX Service Error
Refer to the following link for more specific information related to this error. HP Printers 49.XXXX Service Errors. HP seems to be very committed to taking care of these 49 errors and each time I’m stuck reading through HP documentation online I’m always coming across new firmware and driver updates to help remove some of these pesky errors.
I was going to cover the fuser issues in this article but after starting I realized that the subject is too large to put in this article so look for a future article discussing in greater detail the problems related to the fuser and swing plate assembly. Hopefully, as with the rest of the articles, this has provided some insight to the errors and issue you may be dealing with when servicing HP LaserJet 4200, 4240, 4250, 4300 or 4350 printers.
