In general, a 49 service error is a situation where the printer cannot process a file that has been sent. In some cases the file is corrupted and in other cases the printer`s firmware simply cannot interpret that file.
This error can be caused by having insufficient memory on the device. e.g. multiple apps are installed on the MFP at the same time. Note 💡 It is recommended for the PaperCut partner to do the steps below, as opposed to the end customer, as the MFP will need to be reconfigured with PaperCut Hive and PaperCut MF.
A 49 error typically occurs when the printer attempts to perform an action that the firmware is not capable of performing or might not be designed to handle, for example: Printing files that include unsupported printer commands. Interfacing with a third-party solution that was not designed to work with the printer.
This error might happen at any time for multiple reasons. The most common causes are due to the printer being asked to perform an action that the firmware is not capable of, and might not have been designed to perform, such as: Printing files with unsupported programming commands.
Some random crash 49.38. 13 may happen when the BarDIMM Pro is installed in the printer equipped with that firmware and other solutions. The defect is fixed in HP Futuresmart 5.2 firmware. If your HP printer does not have Futuresmart 5.2 available, we recommend you downgrade to Futuresmart 4.11.
This error might happen at any time for multiple reasons. The most common causes are due to the printer being asked to perform an action that the firmware is not capable of, and might not have been designed to perform, such as: Printing files with unsupported programming commands.
The problem was a combination of an incompatible print file in the print queue that caused the printer to display the 49 service error and then immediately re-start–a vicious loop with a short re-cycle time.
Most times the 49 error is a firmware error and not a driver error. It is usually casued by a bad print job trying to print and confusing the printer. You need to disconnect the printer from the computer and/or network and turn the power on and see if the printer comes to ready.
This is a hardware error generated by the printer firmware and relates to the paper size sensor which would fit with the different thickness of stock. The later 4200 drivers were modified to reduce the error occurring but if you have older firmware and/or older drivers on the PC it would be worth updating.
A 49.38. 0C indicates an internal firmware error has occurred. The root cause of this can vary depending on the version of firmware running on the device. Knowing what version your HP LaserJet CP5525 is running would help us in diagnosing the issue.
Your HP LaserJet Pro M1536dnf MFP printer is designed to work with original HP 78A toner cartridges. Only original HP CE278A, CE278D toner cartridges can provide the results your printer was engineered to deliver.
If it does it means there is a print job trying to print to that printer causing the error. You will need to remove the printjob, reconnect the printer, turn it on and first thing update the firmware to the latest version.
If you have NOT recently replaced the fuser or heavily jostled the printer around, then the 50.7 Fuser error indicates you have an actual fuser failure (the gearing pressure is not releasing) and the fuser needs replacing.
This is a hardware error generated by the printer firmware and relates to the paper size sensor which would fit with the different thickness of stock. The later 4200 drivers were modified to reduce the error occurring but if you have older firmware and/or older drivers on the PC it would be worth updating.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.

Error Code 51.1 says Printer Error No Kidding.lol
ANSWER : Sometimes turning off and on will allow you to print a few pages. The error is a beam detect error. The only real fix is to replace the laser scanner unit. Could be a loose connector on the scanner or DC controller from the scanner. That’s unlikely. You could try the only other free fix which is to open the scanner assy. and clean all the mirrors inside. The dust could obstruct the laser beam enough to cause the detect error.
