Printhead Carriage Positions Error -6530 / TT750

TTOParts Videojet 6530 printhead carriage position error
The new Videojet and Linx all-electric printers have revolutionized the printing industry with their exceptional performance. However, like the old TTO printers, these printers can encounter calibration failures, which can be frustrating for users. In this blog post, we will explore some common causes of calibration failure and provide troubleshooting tips to help you overcome this issue.

Printhead Carriage Movement:
One of the primary reasons for calibration failure is restricted movement of the printhead carriage. To ensure proper calibration, make sure the carriage can move back and forth freely. Check the timing belt and linear slide mechanisms that enable carriage movement. Sometimes, these components may become misaligned or obstructed, causing calibration errors. Inspect them carefully for any signs of damage or wear.

Pivot Assembly Belt Clamps:
The pivot assembly belt clamps, located at the rear of the carriage, can shear and cause calibration problems. Although they might not be immediately visible, you can perform a simple test to check for excessive slop. Move the carriage back and forth while observing any abnormal movement. If you notice excessive play, examine the timing belt and pivot clamps for potential damage or misalignment.

Ribbon Peel Arm:
The proper alignment of the ribbon peel arm is crucial for accurate calibration. To check for any issues, move the printhead up and down and inspect the gap between the printhead and the white roller of the peel arm. If the gap is too close or if the components are impacting each other, calibration errors may occur. Ensure that the peel arm is not bent and that there is sufficient clearance between the printhead and the peel arm's roller.

Printhead Carriage Drive Motor:
If all mechanical causes have been ruled out and calibration failure persists, it might be time to consider the printhead carriage drive motor. The drive motor is responsible for moving the printhead carriage accurately. If the motor malfunctions or experiences a fault, it can result in calibration issues. Consider swapping out the drive motor if necessary, following the manufacturer's guidelines.

Calibration failure can be a frustrating issue when using Videojet and Linx all-electric printers. By understanding the potential causes and implementing the troubleshooting tips provided, you can address these problems effectively. Remember to check the printhead carriage movement, inspect the pivot assembly belt clamps, examine the ribbon peel arm, and consider the printhead carriage drive motor as potential sources of calibration failure. With these steps, you can overcome calibration issues and ensure the optimal performance of your printers.
