Printers use a weird language. When something is wrong with them, they won’t just tell you what’s going on. Instead, they’re going to send off a weird jumbled string of digits and expect you to know what that means. How rude! Fortunately, we’re here to provide you with… What we're going to discuss today: An extensive HP printer Error Code list!HP Error Code 49, also known as HP Error Code 49.4 c02HP Smart Test Error Code 303HP Recovery Manager Failed Error Code FFFFFF 15, also known as HP Error Code 0xe0ef0003HP Error Code 0x83c0000a, also known as HP Error Code oxc4eb827fHP printer Error Code 79HP Printer Error Code 30HP Error Code 0xc19a0003, also known as HP Error Code 0xc19a0013 and HP Error Code 0x61011bedHP Printer Error Code 0x6100004aHP Error Code biohd-8, also known as HP Error Code biohd-2HP Error Code 601HP Error Code 3f0HP Error Code 0xc0000225, also known as HP Error Code 0xc0000034 and HP Error Code 0xc000000fHP Error Code 0xc000021a, also known as HP Error Code 0xc0000185HP Error Code 0xc00000e9 An extensive HP printer Error Code list! Regardless of the model of HP printer or computer you own, you’ll find an easy step-by-step on how to fix each of the errors below. A lot of the error codes have the same troubleshooting behind them in order to get the printer or device working, so we’ve bunched those up together to lessen confusion and get you back to printing. So, let’s get to the bad guys keeping your papers hostage and your screen blue. HP Error Code 49, also known as HP Error Code 49.4 c02 Let’s start with a common one, but a pesky nonetheless. The HP printer error code 49.4c02 will usually stick your printer in a loop, telling you to turn it off then on but keep reappearing. How to fix it? In a typical scenario, this pops up as an HP OfficeJet 4630 error code because something is messed up in your printer queue and you should clear it. If you’re worried about losing printing jobs, you can save them before you clear the queue, Regardless, this should fix the HP printer error code 49.4 c02 most of the time. If it doesn’t, that means your printer needs a firmware upgrade, so you’ll have to go to the HP downloads section and get the latest firmware for your HP printer model, then restart the printer. If you’re still getting the HP error code 49.4c02 after this, one of the many hardware parts inside the printer has malfunctioned and needs to be replaced. (or the printer itself, if you prefer) HP Smart Test Error Code 303 This is one nasty error to get. Why? Because, while some errors have a straightforward fix and are usually related to the printer, the 303 HP error code means that your hard drive is failing in some way. So, the good news is that the 303 is not a printer issue, but rather an issue with your computer’s hard drive. The bad news is that you’ll have to replace that hard drive, so we suggest you back up all the data on it as quickly as possible before it malfunctions even harder, and then get a new one. HP Recovery Manager Failed Error Code FFFFFF 15, also known as HP Error Code 0xe0ef0003 You’ve backed up your files through the HP Recovery Manager and are now getting the FFFFFF 15 error. That means one of two things: either your hard drive doesn’t have enough space to recover the backed-up files or there is an issue with the hard disk on your computer. First, try clearing up a few gigabytes of space on your hard drive in safe mode, restart the computer and see if you’re still getting the error. If you are, run Command Prompt, type Chkdsk /f, press Enter and restart the computer. This will do a sweep that will verify the integrity of your drive. If this still didn’t help, it means a mismatch occurred when you were changing your operating systems between Windows 7/8/10. Here, you are pretty much in no man’s land and the old Recovery is most likely useless. Some call this the HP Envy Error Code: the user wasn’t satisfied with the manufacturer’s operating system and thought they could do with an upgrade (or downgrade). More often than not, however, this error translates to a failing or malfunctioning hard drive. HP Error Code 0x83c0000a, also known as HP Error Code oxc4eb827f The same error code can also come as HP Printer Error Code 0x83c0000a, HP OfficeJet 4630 Error Code oxc4eb827f, HP Envy 4500 Error Code oxc4eb827f and HP Envy 4500 Error Code 0x83c0000a nos_loader_app. Yep. Lot of aliases for this bad guy. This is a very general error that has various general fixes that may or may not work for you, although you should try each of them. Like we said in the title, while this can be a HP Envy 4500 Error Code 0x83c0000a, it just as often happens on different models of HP machines. The first thing you should do is turn off the printer, unplug the power cable and wait 60 seconds before plugging the cable back in and turning the printer on. If the HP Error Code ox83c0000a nos_loader_app persists, you can try unplugging and reconnecting the router, and if it still persists, you can try realigning the ink cartridge as the printer is turning on, or otherwise check that the cartridge is properly placed if you haven’t done so already. Usually, you get these when something went wrong with the initial printer setup. If none of these solutions worked, the printer almost certainly malfunctioned and is in need of repairs or replacement. HP printer Error Code 79 You’ve switched from ink to laser because it seemed more modern, but sheesh, the errors are still coming. The HP Printer Error Code 79 is exclusive to laser printers and is very easy to solve. It’s nearly always caused by one of two things: a print job being corrupted or the firmware being updated. So you don’t lose your print job, we recommend updating the printer’s firmware to the latest version, then restarting both the computer and the printer. In our experience, this has most often been a HP P2015 error code. If you’re still getting the error, you’ll have to clear your print queue as it’s difficult to tell which of the print jobs in it is corrupted. HP Printer Error Code 30 Usually, this error code will tell you that the printer isn’t activated even if it’s connected to both the wall plug and the computer. The issue is straightforward: there is a problem with your drivers, and it’s best to do a clean sweep even if you already have them installed. If only all of the entries on our HP printer Error Code list were this easy to solve. Go to your Control Panel and find your printer, then uninstall it. Then, find any HP drivers on the computer you might have and remove them as well. Disconnect the printer from the computer and connect it again, then go to HP’s official web page, find your printer model and download the full driver suite for it. HP Error Code 0xc19a0003, also known as HP Error Code 0xc19a0013 and HP Error Code 0x61011bed This one is a straightforward ink cartridge issue. The first step to do to try and fix the HP Printer Error Code 0xc19a0013 is to turn off the printer, unplug it from the wall cartridge and turn it back on. This will cause the printer to realign the cartridges. If the HP printer Error Code 0xc19a0003 still persists, you might have installed the ink cartridge incorrectly and should check your HP printer manual in order to see you got that part right. Maybe getting HP Instant Ink could be a solution. If the cartridge is aligned properly, that means it’s either low on ink (which you can verify through your computer on either Windows or Mac) or the cartridge is damaged or faulty. Since this is purely a HP printer Error Code, we suggest you check our guide on why remanufactured HP Ink Cartridges can sometimes cause this. There is a slight chance that updating your drivers might help in case they’re outdated, but don’t hold your breath. And, as a last resort, you can try cleaning or replacing the InkJet’s printhead, as it’s possible that an overly-dirty printer head can cause this issue. These errors also tend to pop up when the printheads are failing or broken down. HP Printer Error Code 0x6100004a Depending on your fortune, this is either caused by a paper jam, an ink cartridge or a printer failure. Isn’t our HP printer Error Code list PDF mysterious? To keep things on the bright side, first try removing all of the papers from the printer and then inserting a new one to see if you’re still getting the error. If you are, turn off the printer, remove the ink cartridges, turn it back on and perform a hard reset, then insert the cartridges and do a test print. While you’re there, check the HP ink cartridge to make sure it didn’t break down. If you’re still getting the error, you can try all of the general solutions mentioned in our troubleshooting your HP printer section. If none of them help, there is a hardware malfunction going on. If the cartridges look okay, our first guess would be that the the HP drum unit is failing you. HP Error Code biohd-8, also known as HP Error Code biohd-2 The biohd-8 is a hardware failure issue, similar to the HP Smart Test Error Code 303. The reason we haven’t grouped this up with that one is that, while most cases of a HP Error Code biohd 8 mean that the hard drive is failing, certain users have also reported this to be a motherboard issue. Therefore, if you’re getting this error, it could either be the hard drive or the motherboard, as opposed to the HDD-specific 303. You can verify whether the HDD is failing through various diagnostic tests, like the one available in the system BIOS. Whichever it is, you’ll want your data backed up on another drive as quickly as possible before either sending the computer for repairs or getting a replacement part yourself. HP Error Code 601 The 601 is an issue with the battery on your HP laptop. Use the HP Battery Check tool to figure out what’s going on. It will either tell you that it’s functioning correctly but needs to be calibrated, or confirm that it’s failing and you need a replacement. Before sending the battery or the laptop off, however, try uninstalling the Microsoft ACPI-Compliant Control Method Battery and delete the driver when it asks you to do so. Restart the computer and you will be asked to reinstall the laptop’s battery. If you’re still getting the error, it’s probably time for a replacement. HP Error Code 3f0 This is another one of those general errors that are tough to figure out and are not related to the printer, but rather the computer. This ain’t no HP DesignJet error code: you aren’t being allowed to turn on the computer! Whenever you try to boot it, you get the nasty 3f0. There are some good news here: it’s almost always related to your HP computer’s hard drive, so you’ll know what to look for. The first thing you want to do is enter BIOS as the computer is booting and ensure that your hard drive is set as the primary booting device. If that doesn’t do it, you might want to reset all the BIOS settings to default. In general, the HP 3f0 error code error means that your hard drive can’t be found by the computer, so you could check that it’s properly connected manually (unless doing so will void your warranty). If you’re still getting the 3f0 after all this, it means you need a new hard drive. HP Error Code 0xc0000225, also known as HP Error Code 0xc0000034 and HP Error Code 0xc000000f This is a less common error that prevents your PC from loading up and tells you that it needs to be repaired. Don’t panic, though, as the repairing is usually done on the software instead of the hardware side. That’s right. Finally, something else other than a HP hard drive error code. Depending on the Windows version you have, download the appropriate Windows repair tool and create a bootable USB drive with it on another computer. Turn off the computer that’s giving you the 0xc0000225 error, insert the USB drive and plug it back on, then enter BIOS as it’s loading and choose the USB drive as your primary booting device. After the repairing process is done, you’ll need to reset the primary booting device in the BIOS back to your Windows hard drive. You can also create a bootable repair tool with a DVD and use the DVD drive as the primary bootable device for the repairing process, but really, who’s using DVDs nowadays? HP Error Code 0xc000021a, also known as HP Error Code 0xc0000185 The 0xc000021a is similar to the error above, but not exactly the same. It’s generally indicative of a Windows issue, be it a corruption or something else. Just to make sure, once you’ve been stuck with the 0xc000021a error, restart the PC and quickly tap the ESC button to go to a HP Startup Menu that offers a Diagnostics Tool. Use it to verify that all of the hardware is working. If it’s not, it’s repairs time. If it is, reboot the computer and hit the ESC button again. Depending on how diligent you were before, you will either have the option to perform a recovery through HP’s Recovery Manager tool or Windows’ own System Restore. If you don’t have either recoveries, you will have to boot the PC with the Windows installation media to try and fix the damage. If it can’t be fixed, it’s time for a fresh Windows install. HP Error Code 0xc00000e9 Again similar to the above, but not exactly the same. This tends happens due to an improperly removed flash drive or a poorly installed Windows update, especially when upgrading your Windows version. This means you’ll have to turn to Windows Recovery or the HP Management Tool again. We recommend the first option if possible, as Windows tends to create a Recovery Point before every update. InkEvolved Tip: You’ve probably noticed that a lot of these errors are related to hard drives, and you’re right. Don’t pay too much attention to the HP device model you own: whether you’re getting a HP Envy 5540 error code, a HP Envy 4501 error code or a HP Envy 4500 error code, always start with a hard drive integrity check when booting to see if there has been a hardware malfunction.
