Know-How: HP Officejet Pro 8500's Hidden Service Menu: Menu structures
The main menu
The MFG menu (Manufacturing-Menu)
In this section, only a grid appears. If you push the Off button, the printer reboots with a message saying "MFG-mode". If you know anything about this mode we would appreciate you sending us an email to email@example.com or posting in our forums, if you have more information on the topic.
The REFLASH Menu
A green screen showing the numbers "1 2 3 4 5" appears. We believe that this rewrites the flash memory to correct possible memory bugs. Afterwards you can only switch the printer off - it immediately reboots and starts a thorough printhead cleaning process.
The AUDIT Menu
A pink screen showing "AUDIT" appears. Turning off the printer will make it reboot in "AUDIT-mode". If you have more information on this mode, we would appreciate an email to firstname.lastname@example.org or a post in our forums.
