Hi @Tmoussa,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Error codes 49 and 75 on HP LaserJet printers can indicate different issues. Here’s a breakdown of both errors and steps to troubleshoot them:

Error 49: Service Error

This error usually relates to a firmware or communication issue. Here are some steps you can take:

Power Cycle the Printer:

• Turn off the printer, unplug it from the power source, wait for about 30 seconds, and then plug it back in and turn it on.

Check for Updates:

• Ensure that your printer's firmware is up to date. You can check for firmware updates on the HP support website.

Disconnect and Reconnect:

• If the printer is connected via a network, try disconnecting it from the network and then reconnecting it.

Remove and Reinsert Cartridges:

• Take out the toner cartridges, check for any obstructions, and then reinstall them.

Clear Print Queue:

• Make sure there are no stuck print jobs in the print queue. Clear the queue if necessary.

Factory Reset:

• If the problem persists, consider doing a factory reset of the printer. Refer to the user manual for the steps specific to your model.

Error 75: Invalid Printer Error

This error usually indicates a problem with the printer’s connection or communication. Here’s how to address it:

Check Connections:

• Ensure that all cables (USB or network) are securely connected.

Check Network Configuration:

• If using a network connection, ensure the printer has a valid IP address. You can print a configuration page from the printer's menu to check the network settings.

Restart Network Devices:

• Restart your router or network switch to refresh the connection.

Update Printer Drivers:

• Make sure the printer drivers on your computer are up to date. You can download the latest drivers from the HP support website.

Check for Hardware Issues:

• Inspect for any visible damage to the printer or cables. If possible, test with a different cable or connection method.

Reset Printer Settings:

• Similar to the steps for Error 49, you may want to perform a factory reset.

I hope this helps.

Take care and have a good day.
