Tip & How-To about HEWLETT-PACKARD CM1415fnw AllInOne Laser Printer

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 www.hp.com 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.

49 errors are most commonly caused when the printer receives a print job with commands it does not recognize. You can try updating the firmware as this will often resolve the error. Go to HP's website to find the most recent firmware, however this model is fairly old and likely the firmware update will be fairly old.

hp 4700 49.3066 service error

49.xx errors are mostly caused by invalid print commands, corrupt
data, or invalid operations. Basically the printer "does not understand" the print job.

- restart the printer to clear the print job from the printer's memory.

-if the error returns disconnect the network/USB cables from the unit and cycle power again.
If the error comes back without the network/USB connected perform a cold reset on the device and go the next step.
- Once the unit is at Ready reconnect the network/USB cable.

If the unit gets the 49.xx error or begins to print a job then gets the error disconnect the cables again and power cycle the printer. This time when you plug the network/USB cable in watch the control panel for any signs of the unit receiving a print job. When the printer says "Processing" press the cancel button on the printer. This should clear the "bad" print job.

I strongly recommend updating to the latest driver for the device Drivers Software . If you had an issue with a PDF file use the Post Script (PS) driver.

Good Luck

We've a problem with our TEC printer B-SX55. Sending a job via parallel interface only results in an error message showing up: XS;I,0001,0012C5 Can anyone tell me what to do to get it up and running again?

This type of error message usually means a command error has been found in a command received by the printer. 16 bytes of the command error, hence the XS;I,0001,0012C5 message. It starts from the command code, XS.

I am not sure of all the command codes but I would suggest starting by re-installing the printer driver.
