• Code: F040
• Description: Communication error between controller - Print engine
• Remedy: Main/Engine PWB 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug in the power cord and then turn on the power switch. 2. Repair or replace the wire from the main/engine PWB that may be grounded. (Check for a shortcircuit between 5V and 3.3V.) 3. Check the FFC cable connector connecting to the main/engine PWB and reconnect it. Or replace the FFC. 4. Check both the main and engine firmware, and upgrade to the latest version, if necessary. 5. Replace the main/engine PWB.
