I. Environmental Control

Temperature and humidity are the key external factors affecting the operation status of the FEDAR digital printing machine in winter. Strict environmental control standards must be established to create an appropriate operating environment for the equipment. In winter, the indoor temperature is low, which can cause the ink viscosity to increase and the fluidity to decrease, thereby leading to clogging of the ink supply system and uneven ink supply from the print head. At the same time, the internal circuit components of the equipment may also experience unstable performance due to low temperatures. The winter air is dry, which will intensify the static electricity phenomenon of the printing medium, easily attracting dust, which not only affects the clarity of the printed pattern but also may damage the print head.

II. Maintenance of Core Components

The print head, ink supply system and transmission system are the core components of the FEDAR digital printing press. During winter maintenance, attention should be focused on these key parts and targeted maintenance measures should be formulated to ensure their stable performance. The print head is the core component that determines the printing quality. In winter, the ink has poor fluidity and if not properly maintained, it is very likely to cause clogging problems. The smooth operation of the ink supply system is the foundation for the stable production of the equipment. During winter, special emphasis should be placed on maintaining the ink at a high temperature, cleaning the pipelines and maintaining the filters. The low temperature in winter may cause the lubricating oil of the transmission system to increase in viscosity, resulting in a decline in lubrication effect and accelerating component wear, thereby affecting the operating accuracy of the equipment.

III. Daily Operating Procedures

Before starting the equipment every day, a comprehensive inspection should be conducted, including checking whether the power lines are intact, the air source pressure is normal, and whether the connections of all components are secure. Once all abnormalities are confirmed, the equipment can be started. During the production process, the surface of the equipment should be kept clean. Any ink stains, fabric debris, and other impurities generated during the printing process should be promptly cleaned to prevent them from entering the equipment and damaging the components. After the daily production is completed, the shutdown procedure according to the equipment operation procedures should be followed, including cleaning the print head, shutting down the ink supply system, cutting off the power supply, and closing the air source.
