Has my printer been hacked? HELP!

Laser Jet Pro MFP M477fnw
Microsoft Windows 10 (64-bit)

Okay so I think my printer has been hacked or something happened and I need your help. All at once my printer started printing out one line code on all the paper. I cant stop it. I hit cancel hold it down and it will cancel but go right back to doing it until the paper stops. I tried unplugging it and plugging it back in but that doesnt fix it. What are my options and how do I fix this?

This sounds like the printer driver went corrupt.Have you tried to stop the print spooler and restart the spooler?Maybe uninstall the driver and reload the latest driver and firmware for your printer.

Hope that will work.

Has my printer been hacked? HELP!

Hi kylereu,

 

It sounds like someone sent a print job to your printer that causes it to salad shoot.  The job might be corrupt, or it might be an invalid file. If you can identify what it is, there might be some additional steps to debug.

 

If you're concerned that you're being hacked, you can setup some security features for the printer.  For example, you can either setup the printer on a secure network or you can setup access control to restrict the devices that are allowed to print on your printer.

 

Please share if you'd like additional info or suggestions here.

Thank you for your reply. We actually found out what the issue was and it was that our computer had become infected with a virus. I'm sure that what you explained can cause the same symptoms too but just wanted to reply to this explaining what actually was wrong so if someone comes across this problem themselves they know what we had to do to fix the issue. It took a lot of work fixing the damage the virus caused and it wrecked havoc on our computer and the accessories connected to it.

Sorry For the Inconvience caused to you 

 

It might happened because of Network or might be because of Drivers  or might firmware needs to be updated 

 

The Steps to be followed 

1. Keep the Printer in stand alone (If any Network or USB cable is connected Disconnect them) and Check you are getting the same issue or not , if not , Check the Firmware date code by Printing the Configuration page 

2. If the Firmware is not updated needs to be updated from hp.com Website 

3. Need to clear  the  Print Spooler 

Type windows and R button in the Keyboard then Type Spool - Printers and Delete if any File 

4, If the same issue persist change the Drivers if Using PCL6 or PCL5  Change it to PS again the Drivers will be available in hp.com Website 

5. If Same issue , Go ahead and Change the IP address for the Printer

HI there, 

 

I don't think your printer has been hacked, for double confirm, please make sure your printer FW has been upgraded to latest version, which will guarantee you have the most secure solution HP could offer.

 

I think your garbled printing may came from one of your network user,  you could trace the printing logs by accessing to printer EWS page, and check on "Color User Logs",  which will show you which printer job came from which job and which useM477_color_usage_log.PNG
