Code :

Code: W16
Display: Fuse Cut Error
Description: For the new Customer Replaceable Consumable (imaging drums, transfer belt or fuser) just installed, the printer did not detect the CRC’s “new/used” fuse blow. An internal fuse of a new CRC ordinarily blows a few seconds after the CRC is installed. If the fuse cannot be blown, then the consumable’s counter can't be reset and the “consumable expired / replace” messages will not go away.
Remedy: 1. Remove the CRC. 2. Cycle the printer’s power. 3. Install the CRC again. If the error still occurs, try a different CRC. 4. If error reoccurs with a different CRC, replace the engine controller board. 5. Replace the print unit chassis.
