Product: HP DesignJet Z9+ 24-in PostScript Printer

I just turned on my Z9 for the first time in about a year.  I am selling it to a friend but I am unable to locate the password. Please advise on the process to reset the password of this device. Thank you!

Hello Z9Rusty_2020 ,

Thank you for reaching out. Regarding your query HP DesignJet Z9 W3Z71A Admin Password Reset that you’re experiencing.

 

To reset the HP DesignJet Z9 W3Z71A admin password, perform a factory reset on the printer, which will erase all settings including the password. This can be done through the printer's control panel by navigating to Setup > Restore Defaults > Restore Factory Defaults. Alternatively, use the HP Smart app to access Advanced Settings > Settings > Restore Defaults > Restore Factory Defaults


Kindly review the instructions as below :

- please share more details about both printer and ink cartridges

- we recommend both printer and ink cartridges to be HP only

- We at HP do not encourage using 3rd party accessories or devices , hardware upgrades unless advised in any form of hp documentation

- Find all relevant guides and drivers from the support page here on best effort basis with the limited details that we have about the device  -

This will help us narrow down the cause and suggest the best fix

I am an HP Employee. Although I am speaking for myself and not for HP.
