As winter sets in and temperatures drop, it's crucial for businesses utilizing digital printing equipment to be mindful of the impact on their machinery. The cold weather can adversely affect the performance of inkjet printers, specifically targeting the nozzle – a core component of these printing devices. Issues such as oblique spraying, flying ink, and disruptions in drawing can arise if proper precautions aren't taken. Let's explore the factors that can affect printing nozzles during winter and discuss effective methods to mitigate potential damage.
1. Temperature
As the mercury falls, the ink's viscosity increases, leading to a phenomenon known as "false clogging." This manifests as temporary disconnections of some nozzles during high-speed printing. Adjusting the platform's front and rear heating can help combat issues like "ink accumulation."
2. Battling the Dryness
Winter air tends to be dry, and low humidity can cause ink residue on the printing head to dry up, creating the illusion of a "blocked nozzle." Moreover, dry environments pose a risk of DTF film warping, especially for paper-based consumables. Employing a humidifier can alleviate these issues by maintaining indoor humidity. This small investment can prevent damage to the nozzle and motor caused by material touching the nozzle after warping.
3. Static Electricity Control
Static electricity is a common issue in winter and can significantly impact the lifespan of digital printing machines. These tips can help mitigate static electricity:
- Use a humidifier to maintain air humidity between 35% - 65%. Keep the humidifier at a safe distance from the main board to prevent condensation and short circuits.
- Control printing speed to prevent excessive static electricity buildup.
4. Dust prevention
Dust is a silent adversary that can easily clog nozzles, leading to image disconnection during printing. Regularly cleaning the nozzle is crucial to prevent dust buildup and ensure consistent performance.
