2024-07-12

POLYTECH's customers are located all over the world, each country with its own unique customs and holiday schedules. We often receive inquiries from customers about how to maintain their machines during holidays, especially during the Christmas and New Year holidays, when machines may be completely idle for 2-3 weeks. Customers are concerned about how to best protect their printers and printheads so that they can quickly resume production once the holidays are over. Below, we provide POLYTECH's DTF solution holiday

Maintenance plan:

Maintain workshop conditions: 10-28°C and 40-80% humidity is highly recommended.

- For 7 days: shut down the printer normally.

- For 8-15 days: load ink for 15 seconds, then shut down and lock the waste ink tube.

- For 15-30 days: replace white ink with a cleaner, clean the nozzle until all white ink is replaced by cleaner, then fill inks for 15 seconds, shut down, and lock the waste ink tube.

- For over 30 days: wash away all inks with cleaner, return the carriage to its original position, tighten the ink tank cap, close the ink tube clip, and unplug the power cable. Prevent dust and rat infestation in the workshop. Check cables before restarting after a long period.
