Menu structures

The main menu

  • MFG
  • REFLASH
  • AUDIT
  • 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 info@druckerchannel.de 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 info@druckerchannel.de or a post in our forums.
