HP Printer 79 Service Error

The HP Printer 79 Service Error typically indicates a firmware issue or a problem with the printer's internal processing. Here are some steps you can take to troubleshoot and hopefully resolve the issue:

1. Restart the Printer

To restart the printer:

Turn off the printer and unplug it from the power source. Wait for about 30 seconds. Plug the printer back in and turn it on.

2. Check for Firmware Updates

To check for firmware updates:

Visit the HP Support website and navigate to the downloads section for your specific printer model. Download and install any available firmware updates.

3. Reset the Printer

For some HP models, you can perform a factory reset:

Go to the printer's control panel. Navigate to the Advanced Setup or Service Menu (the exact location may vary). Locate the Reset Printer option and follow the on-screen instructions.

4. Clear Print Jobs

If a stuck print job is causing the error, follow these steps:

On your computer, go to the Start Menu Control Panel Devices and Printers. Right-click on your printer and select Properties. Go to the Printer Properties Print Jobs tab and cancel any pending print jobs.

5. Check for Hardware Issues

To check for hardware issues:

Make sure there are no paper jams or obstructions in the printer. Check the cartridges to ensure they are installed correctly and are not empty.

6. Reinstall the Printer Drivers

To reinstall the printer drivers:

Uninstall the printer drivers from your computer. Download the latest drivers from the HP Support website and reinstall them.

7. Contact HP Support

If the error persists after trying the above steps, it may be necessary to contact HP support for further assistance as it could indicate a more serious hardware issue.

Additional Tips:

If the printer is connected to a network, try connecting it directly to the computer via USB to see if the error still occurs. Ensure that your printer is not connected to a surge protector or power strip as this can sometimes cause power issues.

HP Z6100 Printer Error 79-04

The HP Z6100 Printer Error 79-04 can be equally frustrating. Here are some fundamental steps to help you resolve this error:

1. Check the Printer’s Supply Status

To check the printer’s supply status:

Extract the Service Plot or view the information on the front panel. Replace any cartridges or print heads that are out of warranty or show more than 100 wear. It is recommended to switch to HP ink if you are currently using non-HP ink.

2. Use the Repair Tool

Follow these steps to use the repair tool:

Download the appropriate repair tool and save it to your desktop. Navigate to the file location and double-click it to start the installation process. Select the option to uncheck the checkbox for automatic scanning. Click Install to begin the process. Once installed, the tool will download any updates and perform a preliminary scan to identify unhealthy areas on your PC. Click Start Repair to complete the process. Your computer may require a restart.

3. Troubleshoot the HP Z6100 Connection

Follow these steps to troubleshoot the connection:

Ensure that the HP Z6100 printer is the only device connected to the parallel or USB port. Switch to a different cable. For parallel cables, ensure they are less than three meters long and IEEE-1284 compliant. On the computer, try a different parallel port mode. If necessary, consult the computer’s documentation or contact technical support.

4. Troubleshoot Software Issues

To troubleshoot software issues:

Send the exact same file that caused the system error. If the error occurs again, try generating the file and printing it. Send a different file from a different program. Check that the proper printer driver is being used and verify if there is a new driver release. Uninstall and reinstall the printer driver with the most current version available. Set all other printer drivers that are set to print to the same port as the HP Z6100 to Print to File in the driver settings.

By following these steps, you should be able to resolve the HP Printer 79 Service Error and the HP Z6100 Printer Error 79-04. If the issue persists, don’t hesitate to contact HP support for further assistance.
