Polyprint Echo2 Feature - Auto-Height Adjustment  | Screenprinting.com

The auto-height adjustment feature on the Polyprint Texjet Echo2 DTG is a great feature that allows for consistent high-quality printing and provides a safeguard against head strikes. This feature will bring the garment into the machine and automatically bring it to the optimal height for printing. 

Why does this feature matter? 

The distance between the print head and the medium, apparel in this case, is a key component to print quality and performance on a DTG. If the garment is too far away from the print head, the ink will not be placed in the exact position intended and you will experience “fuzzy looking” prints. Another example of this looks is when your prints come out looking out of focus. 

If the garment is too close to the print head, two major things can happen. 

  1. The printhead will strike the garment and damage the print head.
    1. In most DTG printers, including the Echo2, there are sensors that will not allow head strikes. In the case of the Echo2, you will see an error message on the printer and you will be unable to print.
  2. The second thing that can happen is the print head can strike fibers sticking up from the garment. This causes incorrect printing and excess fibers will build upon the print head leading to possible damage of the head.

This is also a great feature when switching from thin to thicker materials and vise versa. When you change from printing on t-shirts to sweatshirts, the platen needs to be lowered. Using the auto-height adjustment will guarantee that you are printing at the optimal distance between the now thicker garment than previously. This is a key component in providing your customers with consistent printing.

How is this better than a lever or manual height adjustment?

Some DTGs offer height adjustment in the form of a lever adjustment with steps for the different heights you can set the platen too. While this will get the job done, having a vertical servo-motor controlling the adjustment gives a more exact option when adjusting the platen height. 

Also, you will sometimes experience the height sensors being triggered when doing double pass printing. *Double pass printing is commonly seen when you print the white underbase first and follow up with the colors of the design after. The garment will go in and out of the printer twice. At times, the fibers in the shirts can come up in between passes. This will trigger the height sensors and you will have to lower the platen. With the Echo2, the adjustment is extremely smooth to provide as little movement as possible. This will help you to not move the garment out of registration causing the second pass to be misaligned. At times, you can experience the garment becoming out of alignment when you are having to lower the platen with a lever or manual height adjustment.
