Common error codes on HP printers

Modern printers and multifunctional devices are equipped with a self-diagnosis system that allows for the detection of malfunctions in all components of the device. When there is a problem with the equipment, the microprocessor sends a code signal to the user indicating the malfunction. The code can be displayed on the device’s screen, if available, or by the alternating blinking of LEDs on the control panel. In addition, the error message with the code may also appear on the computer screen.

Despite their overall reliability, printers and MFPs manufactured by HP (Hewlett-Packard) are not exempt from operational malfunctions. According to user feedback, the most commonly reported errors in HP devices are print errors, as well as errors with the codes E8, E3, and 79.

Printing failure on HP printers

When attempting to print a document, it is not uncommon for a user to encounter a blockage in the process for an unknown reason. All efforts to delete or cancel the job in the print queue prove fruitless. This issue can arise from various factors, such as a sudden power surge in the electrical grid, but regardless, the problem must be resolved within the "Print Manager" program. This is because, upon sending a document for printing, a designated file is generated within the Windows system. Due to certain circumstances, this file can become corrupted, leading to an unsuccessful printing outcome. As a result, the file needs to be removed using the following method:

1. Power off the printing device using the button and disconnect the power cord from the wall outlet.
2. Create a backup of all work results to prevent loss.
3. Next, open "windows services" by simultaneously pressing the windows + r keys.
4. A window will appear with a blank line, where you should enter "services.msc" (without quotes) and click ok.
5. In the window that appears, locate the line "print queue manager".
6. Click on this line and select "Stop" from the menu that appears.
7. Once the service has stopped, you can close the window.
8. Next, go to the following address: C:Windows\System32\Spool\PRINTERS. You can do this by copying and pasting it into the address bar of Windows Explorer, then pressing Enter on your keyboard.
9. Remove all the files inside the opened folder.
10. Shut down the computer.
11. Prior to connecting the MFP (printer) to the power source, ensure that it has been powered off for at least 60 seconds.
12. Power on the MFP (printer) by pressing the power button.
13. Switch on the computer and wait for the operating system to start up.
14. Submit the document for printing.

If the printing process proceeds without any issues, then the setup is considered to be complete. However, if you are still unable to print the document, there is a solution available with the assistance of free software provided by HP. This software is known as "HP Print and Scan Doctor" which serves the purpose of resolving printing-related problems as well as diagnosing any issues with the equipment. You can obtain this software by accessing the official website through the following link. Once you have accessed the software, upon opening the program window, select the option to automatically search for problems and rectify them. After the program completes its tasks, attempt to print the document again.

There are certain measures which may prove beneficial in resolving this particular problem, depending on the circumstances.

1. To resolve the issue, you should reinstall the printer driver. However, before that, you need to uninstall it. Open the "Devices and Printers" window in the "Control Panel" and locate the HP printer icon. Click on it and choose "Uninstall". This will remove the previously installed driver from your system. Don’t forget to restart your PC after the uninstallation. If you don’t have the drivers for this particular model of MFP (printer), you can download them from the HP website via this link.
2. If you are still unable to print, try temporarily disabling the firewall and attempt to print the document again.
3. If the above steps don’t work, try logging in under a different account (especially if the device was initially configured on a different account).

How to eliminate error e8

The error code e8 frequently occurs on laserjet 1132 MFPs and indicates a scanner problem. According to the device instructions, this fault is considered fatal and cannot be resolved. However, resourceful individuals have discovered various methods to remedy this issue, which may potentially restore the scanner’s functionality.

One prevalent situation is when the scanner ruler becomes stuck in the furthest right position and remains immobile. In such cases, the MFP’s display will show the E8 error.

In this situation, the printer’s carriage is currently experiencing a simple jam. To resolve this issue, you will need to take out the scanner glass and adjust the ruler so that it is positioned in the middle of the device or closer to the left side. To remove the glass, carefully unscrew the six screws that are positioned around the outer edge.

You will require a star hex to loosen the screws.

Once the glass cover has been removed, proceed to take the carriage and move it closer towards the center before placing the glass back in its original position. Switch on the machine and patiently wait for the ruler to situate itself (it should move to the leftmost position). If this happens, then consider yourself fortunate as the E8 code can also potentially arise due to other causes.

In the event that the scanner carriage moves in a jerky manner and comes to a stop after the MFP is turned on, with the E8 code appearing on the display, you will need to inspect all the components of this unit. To examine the scanner unit, follow the same instructions as mentioned earlier in order to remove the glass cover, and then proceed to take out the unit itself and flip it over. On the underside of the block, you will observe two gears and an electric motor pressed against a plate. Carry out the following steps subsequently.

1. First, it is advised to unscrew the 2 screws on the plate and inspect the gears: checking for dirt or damage on the teeth, ensuring there is no backlash, examining the axle that holds the gear for any signs of wear and tear, and so on.
2. Clean any dirt that may be present on the optocoupler.
3. Verify the quality of the loop connection.
4. Once the inspection and replacement of faulty parts are complete, apply some grease (such as thermal film lubricant) to the gear bushings and the guides on which the scanner unit moves.

Typically, following the steps mentioned above resolves the scanner issue in the hp m1132 MFP. However, in certain instances, this problem might be due to the gears being tightly pressed or the optocoupler. Occasionally, reducing the pinion pressure or removing the small pinion can eliminate the problem. To check, turn on the machine (without the scanner unit and upside down) and observe the rotation of the gears. If they continue to move irregularly, it may indicate an issue with the optocoupler.

If you closely examine the optocoupler, you will notice a notched disk positioned between the two sensors. This disk should be correctly aligned in the center of the optocoupler. Sometimes, it may shift to one side, resulting in the E8 code appearing. Ensure that the motor is installed in a manner that centers the disk between the sensors.

In the event that the E8 code reappears even after performing all the aforementioned steps, it could indicate a problem with either the motor or the control board. If you possess the necessary skills and knowledge, you could attempt replacing the motor on your own. However, if that is not the case, you will need to take the control board to a professional service center.

Eliminating the problem with code E3

Users of HP MFPs often encounter the E3 code displayed on their devices. When referring to the device manual, this code translates to "Cartridge is missing or installed incorrectly." It is possible that the cartridge is simply not installed properly, foreign objects have found their way underneath, or the cartridge itself is damaged. However, there are instances when the device fails to recognize the cartridge due to the lever, which has a flap, not reaching the optron. To access it, the rear (metal) cover of the MFP needs to be removed. This video from a foreign source provides a clear demonstration of how to unlock the lever and reset the E3 error (no knowledge of the language is required).

Troubleshooting Error 79

Error 79 with HP printers commonly indicates a software malfunction. To fix this issue, follow these steps:

• Use the shutdown key to power off the machine.
• Wait for at least 30 seconds.
• Power on the unit again and allow it to initialize.
• If the printer was connected to a surge protector, try plugging it directly into the socket this time.
• If the error message still persists, clearing the print queue or reinstalling the driver may help resolve the problem.

Resetting errors on HP printers

If you need to reset the error or maintenance message on your HP printer, there are multiple methods available, but they are model-specific. HP offers a wide range of printer models, so to easily reset the service messages related to any particular issue, you can refer to the tables provided below.

If you need to refill cartridges (LaserJet 1300, 1320, 4250/4350) that have a chip, you should tape the chip before installing the cartridges in the device. The device will display a message that a "left" cartridge is inserted, but it will still function properly. If you encounter any issues, you can refer to the table below for recommendations on resetting the chips.

To reset almost any service codes indicating errors on HP Photosmart series printing devices, follow this method:

1. Press and hold the left arrow key, then press the "Setup" key without releasing it. Release your fingers from the keys. The "Enter Special Key Combo" menu will appear. Simultaneously press and release the "Print Photos" and "Red Eye Removal" keys. Then, press and release each key one at a time: "Red Eye Removal", "Print Photos", "Red Eye Removal".
2. Press the right arrow to navigate to "System Configuration". Click OK.
3. Press the right arrow again to navigate to "Hardware failure status: Clear. Press OK to clear" (if this line is not displayed, it means the device was running smoothly before). Note that you cannot start printing at this point.
4. Turn off the device and then turn it back on.

As a result, the error code has been cleared and the device is now able to function as intended.
