[Message] 08 COLD RESET [Description] The printer returns all Printing, PCL, Job, Config, Mem Config, Parallel, Serial, MIO (if installed), and installed personality(PCL, PS, etc.) Menu settings to their factory default configurations, except for page count, MP Tray size, Envelope Feeder size, and display language. [Recommended Action] 
Reconfigure your printer and MIO. When you install a MIO card, to reinitialize the printer's control panel you may need to perform a cold reset. (Note: In a shared environment, this task should only be performed by the system administrator.) To perform a cold reset, hold down On Line while switching the printer ON until 08 COLD RESET appears in the display.
