49.XXXX errors on HP LaserJet Printers

The 49 error is the printer telling you that a command or information it received it did not know how to process. Much like if someone tried to tell you how to do something but spoke a different language than you. The first step to fix this problem is to restart the printer. If it comes to ready, skip down to the next paragraph. If if does not come to ready, you will need to clear any print jobs from the print queue on your computer and then restart the printer again. If the 49 error still occurs, you will need to unplug either the parallel, network cable or usb cable to see if the printer will come to ready with no computer attached, if it does then restart your computer and then reattach the cable. If the printer is on a network, make sure that no computers have jobs in the queue for the printer. Once you have the printer at ready and attached to your computer. you will need to update the firmware as this usually fixes a 49 error. Go to and from this page select "SUPPORT AND DRIVERS". Type in the model of your printer. For most home machines, the new firmware will be shown once you select your correct operating system. For business class machines, there will usually be an option for "cross operating systems (bios, firmware, diagnostics, etc). Once you have downloaded the new firmware file, there will be a readme file attached that explains how to install the new firmware. For many of the newer printers, an Easy Firmware Update Utility is available. It is simply an executable file that finds any compatible pirnters automatically and processes the update. This is the best choice if your printer comes to ready and is connected to your computer via USB.

What does the error message - 49.4C02 - mean?

49 errors are often caused by the printer receiving commands it does not understand. Sometimes hardware failures but not often. To determine hardware or software, turn the printer off. Unplug any network or USB cables attached and turn printer on. If it will come to ready with no cables attached, then likely you have a print job that is causing problems. This can be fixed by installing the latest firmware from Download the Easy Firmware Update Utility version. To install this update you need to have the printer connected to the computer, so check the print queues to make sure that there are no print jobs pending, delete them if there are. Plug the network or USB cable back in. Wait a couple of minutes to make sure that the 49 error does not come back. If printer stays on ready, run the upgrade utility and your problems should be gone. If it is a hardware issue then a different set of trouble shooting steps applies. Post back if this does not fix your problem.

We have an error 49.283 come up on our HPLJ 9050n, how do i fix tis

A 49 error is usually caused by either a corrupt print file or file that the printer does not understand. In most cases updating the firmware will resolve these problems. First, unplug all usb and network cables attached to the printer and power it on. If it comes to ready that is a good sign. Make sure that there are no stale print jobs in the queue of any computer that prints to the printer. Plug the network or usb cable back in and see if the printer continues to stay on without a 49 error. If yes, then go to and download the current firmware for your printer. Most firmware updates for these units are available as an easyupdate utility. Run that utility from any computer that normally prints to the printer. Select that printer from the drop down menu in the utility. After the firmware has been updated the printer will restart and you are ready to go, with your 49 error a past memory.

49.4 C18 laserjet 4345

49.XXXX is a fatal catch-all error. Could be firmware problem, network, print job. If the error occurs when you try to print, clear the print queue. If the error occurs when the printer is just sitting idle, reseat the formatter. Try powering on without the network cable attached. If it still happens replace the formatter. Could be a corrupt print job being sent to printer. Print something else.

One of the hp 9050n printer have 49.2f83 eror what is the solution please

Follow these steps.
1. disconnect all parallel, network and usb cables and power cycle printer. If it comes to ready good.
2. After making sure that all print jobs are cleared from printer queues, reconnect the network cable or parallel cable. If printer stays are ready, good. If it errors again, likely a stale print job that you missed in a queue. Check and start over.
3. When you can get the printer to ready with the network cable attached. Go to and download and install the latest firmware on the printer.

If the printer continues to 49 you can try updating the print driver as well. If the 49 error is persistent, remove the formatter and try to perform an engine test. if the engine test works then you have either a bad formatter or bad memory on the formatter. Remove memory and restart, still error, then formatter it is.If the engine test does not work then you may have a bad dc controller.

Error message 49 on my HP CP 2025 (printer shuts itself off and truns itself back on to see error message 49)

Firmware error:
1. Press CANCEL JOB to clear the print job from the printer memory. 2. Turn the printer off, and then turn the printer on. You can try reprinting the job to see if it was a temporary error. 3. If error persists, try printing a job from a different software application. If the alternate job prints, go back to the first application and try printing a different file. (If the message only appears with a certain software application or certainprint job, try upgrading the printer driver and / or firmware.) 4. If the message persists with different software applications and print jobs, disconnect all cables to the printer that connect it to the network or printer. Turn the printer off and delete the print queue. Then reboot printer AND computer, reconnect cables, and try printing again. 6. Remove all EIO devices from the printer (JetDirect cards, hard drives, etc.). If 49 error goes away, turn printer off, re-install EIO devices one at a time, and reboot printer each time to determine which EIO device is failing. 7. If printing still fails with all EIO devices removed, remove all memory DIMMs or third-party DIMMs from the printer. (Do not remove the firmware DIMM-- printer won't function without this installed.) Turn the printer on with DIMMS missing. If the error no longer exists, install each DIMM one at a time, turn printer on, test printer. Replace a DIMM if you determine that it causes the error. 8. Remember to reconnect all cables that connect the printer to the network or computer. 9. If the error persists, replace the firmware DIMM. 10. If error persists, replace the formatter.
