To ensure the continuous and stable operation of digital printing equipment and extend its service life, standardized daily maintenance is crucial. The following outlines the maintenance requirements for core components and environmental control standards, for reference by equipment operators and managers.

I. Core Component Maintenance Execution Standards

Raster Positioning System Maintenance 

· Operation: Regularly check the cleanliness of the grating bar surface. When cleaning, use a dust-free cloth with analytical-grade alcohol to gently wipe in a single direction to remove dust and stains.

 · Purpose: Ensure accurate position feedback signals, guaranteeing the precision of ink carriage movement and printing positioning.

Print Head Mirror and Surroundings Cleaning 

· Operation: Move the print head to the maintenance position, check for ink crystallization or foreign objects on the mirror surface and surrounding area. Clean in one direction using a dedicated cleaning solution and non-fiber swabs. 

· Purpose: Prevent clogging of nozzles by dried ink or impurities, and maintain stable inkjet status.

Moke Stack System Function Check 

· Moke Stack Cap: Check its cleanliness and elasticity to ensure good sealing performance.

 · Scraper: Confirm it is clean, flat, and undamaged. 

 · Purpose: To ensure the print head's moisture retention sealing effect and the efficiency of ink scraping cleaning.

Ink Supply and Waste Ink System Management

 · Filter: Check the status of the ink supply filter at scheduled intervals (e.g., monthly) and replace it promptly based on pressure differential or usage duration.

 · Ink Cartridge and Waste Ink Tank: Regularly clean the interior to prevent the accumulation of ink sediment, which can cause pipeline blockages. 

· Ink Sac: Inspect the installation stability and pipeline connections to ensure there is no looseness or air leakage.

Mechanical Transmission System Lubrication 

· Components: Including linear guides, synchronous belt pulleys, gear pairs, ink stack lifting mechanisms, etc. 

· Standards: Use the lubricant specified by the equipment, and replenish or replace it according to the prescribed cycle to reduce wear and operating noise.

Electrical and Auxiliary System Safety Inspection

 · Circuit: Check for signs of overheating or aging in power cords, plugs, and sockets. 

· Air Pump: Monitor and record operating pressure to ensure it is within the set range. 

· Dryer: Inspect its power connection and heating elements (such as lamps, heating rods) to ensure normal function.

Print Platform Status Confirmation:

 ·Before each job, confirm that the platform surface is flat, clean, free of residual media or foreign objects to prevent scratching the print head during operation.

II. Equipment Operation Environment Standards

· Temperature and Humidity: Maintain the ambient temperature between 18-30°C and relative humidity between 35-65% RH.

 · Cleanliness: The operation area should be dust-free and free of oil smoke; it is recommended that equipment rooms adopt a positive pressure dust-proof design. 

· Installation Foundation: The equipment must be leveled using a spirit level and securely fixed, and it should be kept away from large power equipment and other sources of vibration and strong electromagnetic interference.

III. Suggestions for Maintenance Systems

1. Establish maintenance records: Develop and implement a 'Regular Maintenance Schedule' for each device, recording each maintenance item, date, and any issues discovered.

2. Use compliant consumables: It is essential to use original equipment manufacturer (OEM) or certified inks, cleaning solutions, and parts. 

3. Perform inspection before startup: Conduct a simple pre-start inspection daily to confirm there are no abnormalities before initiating production.
