Fix Ml1660 V1.01.00.30.fls ((top)) -

Applying a firmware fix is not without risk. It is a process known as "flashing," which involves overwriting the printer's core operating instructions.

: This is the most dangerous part. If your printer currently has a higher firmware version (e.g., v34 or v35), attempting to flash v30 can brick the device (render it permanently unbootable). You must verify your current version by printing a Configuration Report (hold the Stop button for about 5 seconds until the light blinks). Fix Ml1660 V1.01.00.30.fls
