How to Maintain Digital Textile Printers in Autumn and Winter

The core of maintaining digital textile printers in autumn and winter lies in humidity control, blockage prevention, and component protection, with a focus on addressing the impact of low-temperature and dry environments on ink and equipment.

1. Environmental Control: Stable Temperature and Humidity as the Foundation

The low-temperature and dry environment in autumn and winter easily causes changes in ink viscosity and printhead blockages. The following two points require key control:
  • Humidity First: Maintain the workshop humidity at 45%-65% RH. In dry areas, industrial humidifiers can be used to prevent humidity from dropping below 40%. In humid southern areas, dehumidifiers should be turned on occasionally to prevent components from getting damp and rusty.
  • Temperature Assistance: Keep the temperature at 18℃-25℃ and avoid placing the equipment in an environment below 10℃. Sudden temperature changes can cause ink crystallization. Air conditioners or heaters can be used to stabilize the room temperature, and the equipment should not be directly exposed to air vents.

2. Ink and Printhead: Blockage Prevention is the Key

The printhead is the core of the equipment. The dry conditions in autumn and winter will accelerate ink evaporation, so daily maintenance must be strengthened:
  • Before Daily Startup: Run the printhead cleaning program (2-3 "light cleaning" cycles are recommended). Check if there are broken lines on the test strip. If there are, perform "heavy cleaning" until the lines are complete.
  • During Production Gaps: If the machine is shut down for more than 1 hour, switch to the "printhead moisturizing mode" or manually apply special moisturizing fluid to the surface of the nozzles to prevent ink from drying out.
  • Ink Management: Before use, let the ink acclimate to the workshop environment for 12 hours in advance. Avoid pouring low-temperature ink directly into the ink cartridge, as this may cause abnormal viscosity. Once opened, the ink should be used up within 1 month. The remaining ink should be sealed and stored in an environment of 15℃-20℃.

3. Mechanical Components: Lubrication and Cleaning to Prevent Malfunctions

Low temperatures may reduce the lubrication effect of mechanical components, so regular inspection and maintenance are necessary:
  • Guide Rails and Lead Screws: Wipe off dust on the surface of the guide rails with a clean cotton cloth every week, then apply special lubricating oil (such as No. 3 lithium-based grease) to avoid jamming caused by dry operation.
  • Drive Belts: Check the tightness of the belts. If slipping or cracks occur, replace them in time. Wipe the surface of the belts with alcohol every month to remove oil stains and fiber impurities.
  • Heating Components: Printing media (such as fabric and paper) in autumn and winter are prone to absorbing moisture. It is necessary to check in advance whether the temperature of the heating rollers and drying devices meets the standards to avoid reduced adhesion of printed patterns due to insufficient heating.

4. Long-Term Shutdown: Proper Storage and Protection

If the equipment needs to be out of service for more than 3 days, follow the steps below for storage to prevent printhead damage:
  1. Run the "deep cleaning" program to completely drain the residual ink from the ink cartridges and pipelines.
  2. Inject special cleaning fluid into the printhead and repeat the cleaning 2-3 times to ensure no ink remains in the nozzles.
  3. Turn off the equipment power, unplug the power cord, cover the entire machine with a dust cover, and place desiccants around the equipment to prevent components from getting damp.
