How to Identify and Fix Common Problems ?

You need to ensure your HP printer has enough paper, ink, or toner, and it is not stuck on paper jam. Also, check the status of your printer cartridge and try replacing it with a new one if it is not good enough. In some cases, your HP printer stops printing after you replace its parts.
Right-click on the name of your printer and then select Printing Preferences. Click the Services tab and then click Service this Device. The printer Toolbox displays. On the Device Services tab, click Clean the Print Cartridge(s).
An E0 error indicates an unusable cartridge. This occurs when one or both ink cartridges need attention. Reseat both cartridges, clean the ink cartridge contacts, restart the printer, and replace one or both ink cartridges if necessary.
The only permanent solution to the 0x0000011B error is to install the latest Windows Update which fixes the issue. For now, you can try uninstalling the update or disabling the problematic security feature from the Registry. Other workarounds include installing the printer manually.
0x00000002 – Printer Connectivity Error

The error 0x00000002 means that the driver of this printer installed on the computer is corrupted. First of all, you should try to remove this driver from the driver store (if you get an error 0x00000057).

Error message “0x0000052e” indicates the following error: “Logon failure: unknown user name or bad password.”
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.
An Er/04, Er/05, or Er/06 error message indicates a paper jam. Find and clear the printer of any jammed paper, or reset the printer if the printer has no jammed paper.
If your printer is turned on, disconnect the power cord from the printer. Keep the power plug unplugged for 60 seconds, reconnect the power cord to the wall, and turn on the printer. If the error persists, remove the cartridge from the printer, clean the cartridge contacts with a cloth, and reinstall the cartridges.
1. Paper Jams. Paper jams are a common problem for printers, resulting in time-consuming and frustrating delays. It can occur when loose sheets of paper get stuck in the rollers or feeding mechanism of the printer.
A mistake in anything that`s printed is a misprint. You might also call it a typographical error or typo. Misprints are an embarrassment for the publisher, since they`re evidence of a hasty printing job or a lack of careful proofreading.
In the majority of cases, printers` self-cleaning mechanisms clean blocked printer heads by flushing the nozzles with air. The air works to dislodge dry ink inside the cartridge channels and also push it out. The intensity of the self-cleaning process of printers is usually not very strong.
Deep Cleaning consumes a larger amount of ink than Cleaning. Cleaning the print head frequently will rapidly deplete your printer`s ink supply. Consequently, perform cleaning only when necessary.
Take a warm damp paper towel or coffee filter and blot the cartridge with the printhead facing down onto the paper towel. This will remove any dried ink on the printhead. Then, hold the cartridge with the printhead facing down against a dry paper towel for 2-3 minutes. A dry paper towel will wick the ink out.
Update the Printer Driver

Printer drivers are pieces of software that enable communication between your computer and your printer. The error code 0x00000040 could appear if your printer driver is out-of-date or faulty. Your printer driver may need to be updated in this situation to help with problem resolution.

This seems to be a driver issue, uninstall the printer driver from root level and reinstall the driver to fix the issue. Perform root level uninstallation to remove all the printer related software`s. In Windows, search for and open Programs and Features. Select your HP printer.
While trying to print a document or install a printer, users have been getting the error code 0x0000007c that states the system cannot connect to the printer. As it turns out, this issue has been reportedly caused by an update that was released by Microsoft as part of their security updates.
An outdated printer driver can be the cause of error 0x00000bc4. In this case, we recommend downloading and installing the latest drivers. Try downloading the driver from the printer manufacturer`s website or installing any optional Windows updates.
Make sure the printer is on and connected to your computer. Go to HP Software and Driver Downloads, and then enter your printer model. Select Firmware from the list of drivers, click Download next to the update, and then follow the instructions.
Place the printer near the Wi-Fi router. Open the Setup, Network, or Wireless settings menu, and then select Wireless Setup Wizard. Select the name of your network, and then enter the password to complete the connection.
Right-click your printer and select Properties. Then in the General tab click on the Print Test Page button. If you are unable to print a test page after following the previous steps, you may want to restart your computer. Restarting fixes many hardware problems.
Select Start , then select Settings > Devices > Printers & scanners . Scroll down to Related Settings and select Print server properties. Select the Drivers tab, and see if your printer is listed. If it is, you`re all set.
Use HP Print and Scan Doctor (Windows)

Use HP Print and Scan Doctor on your Windows computer to help diagnose and fix printing and scanning issues. Make sure paper is loaded in the main tray, and then turn on the printer. Download HP Print and Scan Doctor, and then follow the prompts to install and open the tool.

If your printer is turned on, disconnect the power cord from the printer. Keep the power plug unplugged for 60 seconds, reconnect the power cord to the wall, and turn on the printer. If the error persists, remove the cartridge from the printer, clean the cartridge contacts with a cloth, and reinstall the cartridges.

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.
