This code indicates that there`s corrupt data in the the solutions volume. A simple “clean disk” in the admin menu can resolve this error code. I recommend bringing a flash drive with the . bdl firmware file on it and update the firmware after performing this procedure, the printer will require it in most cases.
23 or 30.03. 45 Scanner Errors. The resolution for either error is to, if preferred to send a firmware update, then replace the flatbed scanner assembly. It has been found that it is in most cases the internal lamp that has failed, but is not available through HP as a replaceable part.
99.09.62 – Unknown Disk

This error indicates there is an encryption mismatch between the HDD and the formatter. This typically happens because an HDD was swapped into a device from another device or replaced. Resolution: If the HDD is in the device by error, remove it and return it to its original device.

The 98.02. 02 code indicates that a disk wipe operation was successfully completed. This is an intentional security procedure that is performed on these models every time the power is turned off and then back on.
This SE indicates that one or more printheads are malfunctioning, so I suggest performing the printhead status plot to find out which printheads are malfunctioning, and replace them. STEPS To print this plot, go to the front panel. Vinyl, preferably gloss at least 24 inches wide, is recommended for maximum visibility.
When a 30.03. 23 Error Alignment Calibration Failure appears on the control panel, it indicates there is an issue calibrating the scanner. If there is also a copy or scan quality issue you will see a stripe of lines from the leading edge to the trailing edge of each page.
One such status code is code 45, which indicates an issue with the connected device. The code 45 comes with an error message that says, “Currently, this hardware device is not connected to the computer (Code 45). To fix this problem, reconnect this hardware device to the computer.”
This error indicates a RAM failure. The specific memory is internal memory not one of the dimm slots. You can try removing any additional memory first to see if the device will boot but likely this is a failure of the formatter and you would need to replace the formatter.
Hope you are well, usually that error message stands for paper jam inside the printer, please check the rear door, remove the tray 2 and check for paper stuck.
If you are experiencing an “50.2F. 00 Fuser error”, first turn the printer off and back on. Sometimes the error will temporarily go away with a reboot so you can print a few more pages, but usually the error reappears.
50.2 error indicates that the printer is not heating up fast enough. This can be caused by a bad heating element in the fuser but can also be caused when the printer does not have adequate power due to overloaded circuits or being plugged into a power strip or surge bar that limits current flow.
When a 99.09. 66 error is displayed on the control panel, it indicates one of the following: a hard disk drive or solid state memory drive is not installed. a hard disk drive or solid state memory drive is not connected properly.
63.00. 41 There is an error in the toner supplied to the black developer. HP LaserJet Black Developer Unit: 8JM70-67001 (E783xx series) or JC96-11666A (E778xx series}. If the firmware bundle installed on the printer is lower than 4.6.
Error code e02 occurs due to overheating of the printhead or when the paper is not correctly placed into the input tray and therefore the paper feed rollers are unable to pick up the paper from the paper tray.
the printer is out of paper load the paper or remove the paper and reload it. again flip through the papers before loading the sheets into the printer to make sure that they are not sticking to each other align the edges of the sheets before loading them into the paper cassette.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
