The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
An Er/04, Er/05, or Er/06 error message indicates paper is jammed inside the printer. To resolve the issue, find and clear the printer of any jammed paper, or reset the printer if the printer has no jammed paper.
1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

Make sure your Wi-Fi network and printer setup meet connection requirements. Restart the printer and the computer or mobile device to clear possible error conditions. Make sure the printer is not connected to a computer with a USB cable.
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. SUBSCRIBE RSS FEEDS.
In Event Viewer dashboard, click Applications and Services Logs –> Microsoft –> Windows –> Print Service –> Operational. Right click Operational, select properties. Check the Enable logging box. Click Apply and Ok.
Simply plug the USB cable from your printer into an available USB port on your PC, and turn the printer on. On the taskbar, select the Search icon, type Printers in the search bar, and then select Printers & scanners from the search results to open the Printers & scanners system setting.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
What to do when your HP printer not responding? This usually caused by an incompatible driver. The printer driver is either outdated or corrupted, thus stopping you from printing normally. It can also be your Printer Spooler service, and you might need to restart the service for it to work again.

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.
