DTG M2 Printer Issues: Shadow/Rainbow Print on Underbase

Direct to Garment (DTG) printers have revolutionized the printing industry with their ability to print intricate designs on fabrics. One of the models, the DTG M2, stands out due to its efficiency and quality. However, like any other machine, the DTG M2 can present challenges, especially after replacing parts.

The Underbase Challenge

A recent observation with the DTG M2 pertains to the underbase printing. Following the replacement of the printhead and ribbon cables, the printer started exhibiting a peculiar issue. The underbase, which acts as the base layer for the main design on colored t-shirts, began showing a rainbow effect.

The dilemma escalated when it was found that the new cables accompanying the printhead blew the F2 fuse. Once replaced, and with the old cables restored, the printer worked seamlessly on white t-shirts. Nevertheless, the rainbow effect persisted on colored ones.

Probable Causes and Troubleshooting

Given the circumstances, one might presume that the cables or printhead were at fault. But, when considering that the printer functioned well on white t-shirts with old cables, the diagnosis becomes complex.

Maintenance tasks, such as cleaning the encoder strip, belt, and wheel, were promptly conducted to rule out common issues. These components are crucial for accurate positioning and movement of the printhead, ensuring flawless prints.

Recommendations

For those experiencing similar issues, here are some actions to consider:

1. Double-check all replaced parts for compatibility and ensure proper installation.
2. Test the printer on different t-shirt colors and fabrics to ascertain the scope of the problem.
3. Engage in comprehensive maintenance, including cleaning and recalibrating all relevant components.
