Troubleshooting the Top 5 HP Laser Printing Error Codes / Service Errors.
Of all the tricky repairs we help solve each day, we hear more about a handful of common issues many field technicians encounter regularly. To give you a better handle on these everyday problems, we compiled information on our top five calls, along
with the best way to diagnose and fix them.
HP printer 50 Service Error:
Called among the most mind-boggling errors, the 50 service error can be both the easiest and the most difficult errors to diagnose and fix. It’s the most common problem we help solve and over time, solutions have evolved.
A 50 service error can mean you have an issue with either the printer fuser assembly, a low voltage power supply (LVPS), or a DC controller (DCC). Here’s how to work through each to get to the bottom of your issue:
On newer machines, simply install the new component and if the new part is the answer, your printer should go to ready, with no reset procedure needed to clear the 50 service error code.
If the printer fuser is the reason for your error, check continuity with your ohm meter on the fuser lamp, thermoster, thermoswitch or heating element, depending on your style of fuser. If you have continuity, then the odds are your printer fuser is fine.
If the problem persists, it could be a short in the printer, a damaged cable, pinched cable, exposed wire, or damaged connector.
Next, try the LVPS. Unfortunately, there is no good way to check the power supply; the power supply must be tested under a load, so you need to replace it to get an accurate test result.
If you still have the error, try the DC controller; a fairly rare occurrence. A faulty or weak line voltage, a UPS, or the printer being plugged into a surge protector can also cause this error. Note that some printer model’s, like the 1320, P2015, 2035, 2055 and M401 have no separate DC controller and low voltage power supply. They are combined with the high voltage power supply on one board, usually called the engine controller board (ECU). If you would need to change either the DCC or the LVPS on this style of printer you would need to change the board.
HP Printer 49 Error code:
The second most common error call we receive, the 49.xxxx error, could soon surpass the 50 service error in popularity. It’s difficult to diagnose because there are a wide variety of things that could cause such an error message.
Think of this as a miscommunication between a component and the formatter board, usually an accessory or an option. The easiest way to determine which accessory is causing the error is to remove all accessories and options one at a time, turn on the printer and see if the printer goes to a ready state.
Accessories and options include: Optional cassettes, duplex assemblies, envelope feeders, additional memory, network cards, and hard drives. If after removing one of these devices the printer returns to ready, then the assembly you removed is most
likely the problem and you would need to replace that part.
It goes without saying you should always power off the printer beofre removing any boards or accessories. But in some cases external items that are not installed on the printer could cause a 49 error to occur. Some of these could be: Software, drivers, or networks.
In a “very worst case” scenario, sometimes firmware or the formatter board could cause
these error codes. If it is the firmware on a printer that has flashable firmware, you can try downloading the firmware from www.hp.com and flash that to the printer. If it is the formatter you would need to replace the board.
HP Printer 13 Error code:
As you know, most error codes in HP printers tell you a part or process that has failed, a motor, a fan, a laser scanner, etc. But the 13.xx codes are a bit different and require some detective work to decipher.
To correctly diagnose a 13 error code, you need three pieces of information: the EXACT error number and text, following the code, where the leading edge of the paper is located when the error occurred, and from what trays this error occurred.
It is imperative that you test all trays including tray 1 (bypass tray), in order to have as much information, as possible.
Obtaining the error code from the event log doesn’t provide enough information to properly diagnose the problem. For example, if you have a 13.02 error, but no other information, how do you know what’s wrong? The error indicates the media hasn’t passed the top of page sensor in time. How does the diagnosis change if, in fact, the media has passed the sensor? What if it hasn’t reached the sensor yet?
What if the printer works from tray 1 but not tray 2? All of these factors play a role in diagnosing the problem correctly. Each of these scenarios may result in a different diagnosis, without additional information. Remember, three parts to the process;
