What This Error Means

Error 117.370 indicates a problem with the print head carriage movement, often due to an obstruction or mechanical failure.

Detailed Explanation

The EPSON error code 117.370 typically signifies that the print head carriage, the component responsible for moving the print head across the paper, is unable to move freely or has encountered an unexpected obstacle. This can be triggered by various factors, including foreign objects lodged within the printer's path, a misaligned print head, or issues with the carriage motor or belt mechanism. The printer's internal sensors detect this resistance or incorrect positioning, leading to the error and halting print operations to prevent further damage. This error is essentially a safety mechanism. If the print head carriage cannot move as expected, forcing it could damage the print head, the paper feed mechanism, or the carriage belt. Common causes include small pieces of paper, dust buildup, or even a dislodged ink cartridge interfering with the carriage's travel. Less commonly, it could point to a more serious internal component failure, such as a faulty carriage motor or a worn-out belt.

DIY Troubleshooting Steps

Try these steps before calling a specialist

1
Turn off the printer and unplug it from the power source to ensure safety.
2
Open the printer's top cover or access panel to view the print head carriage area.
3
Carefully inspect the entire path where the print head carriage moves, looking for any foreign objects like paper scraps, paper clips, or even small insects. Use a flashlight if necessary.
4
Gently try to move the print head carriage manually from left to right. It should move smoothly without significant resistance. If it's stuck, identify the obstruction.
5
Check for any dislodged ink cartridges that might be preventing the carriage from moving freely. Reseat any loose cartridges.
6
Use a lint-free cloth lightly dampened with water or isopropyl alcohol to clean the encoder strip (a clear, thin strip running horizontally behind the carriage) and the carriage rails. Be very gentle.
7
Close all covers, plug the printer back in, and turn it on.
8
Attempt to print a test page to see if the error has cleared.
9
If the error persists, try performing a printer reset by unplugging it for 5-10 minutes, then plugging it back in.

When to Call a Specialist

If after performing all the DIY troubleshooting steps, the error 117.370 persists, it's time to consider professional assistance. This usually indicates a more complex mechanical failure, such as a faulty print head carriage motor, a broken or stretched carriage belt, or a damaged sensor that requires specialized tools and expertise to diagnose and repair. Attempting to force the carriage or disassemble internal components without proper knowledge can lead to further, more expensive damage.
