Epson ET-3700 Error 0x44
The Epson ET-3700 is a highly efficient printer that occasionally encounters error code 0x44 related to the scanner display. This error, also known as the “SCANNER” error, arises due to various reasons including PID acceleration lock failure, encoder malfunction, timing belt issues (such as tooth skipping or improper tension), gear cracks, cable or FFC disconnections, motor driver failure, or main board failure.
One possible cause for this error is the failure of the PID acceleration lock mechanism. This component is responsible for controlling the movement of the scanner, and if it malfunctions, the error code 0x44 may be displayed. Another probable cause is an encoder failure. The encoder transmits signals to the scanner, and if it stops functioning properly, it can result in the occurrence of this error.
Timing belt issues can also lead to error code 0x44. If the timing belt has skipped teeth or is not appropriately tensioned, it can disrupt the scanning process and trigger the error. Additionally, a cracked gear within the scanner can prevent smooth movement, causing the error to appear.
Another potential cause is the disconnection of cables or FFC (Flat Flexible Cable) within the scanner. If these components are not properly connected, the scanner may not function correctly, resulting in the error code. Motor driver and main board failures are less common but can also trigger the error message.
To troubleshoot this error code, it is recommended to contact Epson’s customer support for assistance. They can guide users through specific troubleshooting steps or arrange for repairs if necessary, depending on the underlying cause of the error.
