Filament Sensor not clearing/ Filament now stuck

After about 12 successful prints, I switched from Glow to White filament (Prusa Red to HatchBox Glow to Prusa Vanilla White). 

The filament appears to have jammed.  So I shutdown for the night to start with a clear head today.

1: HOW DO I CLEAR THE (print head) filament sensor?
 - The print head filament sensor stopped clearing.  I tried turning it off, but apparently the filament jammed.

2: HOW DO I UNJAM the hotend
- The initial purge for the new White filament worked good.
- But now the filament appears to be stuck.  
       Purge no longer ejects material

3. WHAT MAINTENANCE/CLEANING regime do you use between prints.

4. WHAT ARE SOME OF THE SIMPLE STEPS to clear the problem?
