The HP LaserJet error 75 typically indicates a problem with the printer’s internal memory or firmware. Here’s what you can try to fix it:
- Power cycle the printer: Turn off the printer, unplug it from the power source, and wait for about 30 seconds. Then, plug it back in and turn on the printer. This can sometimes clear temporary issues.
- Reset the printer: Locate the reset button on your printer (consult the user manual if needed) and press and hold it for about 10 seconds. This will reset the printer’s settings to the default factory configuration. Note that this may erase any customized settings, so be prepared to reconfigure the printer if necessary.
- Check the memory: If your printer has additional memory modules installed, try removing them and then reinserting them securely. Ensure that the memory modules are compatible with your printer model.
- Contact HP Support: If the error persists after trying the above steps, it’s advisable to contact HP Support or consult the printer’s user manual for further assistance. They can provide specific troubleshooting steps or recommend further actions to resolve the error.
- Change the chip: one last thing you can try is removing the chip from your old cartridge and putting it on the new cartridge. Sometimes this can check the printer. You may receive a low ink warning by doing so but you should be able to print until the cartridge is empty.
Remember to provide them with the exact error message, printer model, and any other relevant details to help them diagnose the issue more accurately.
