Maintenance Guide for Industrial Jet Printers

1. Printhead and Cartridge Maintenance
a. Preventing Ink Drying

• Perform a small test print every 3–5 days.

• If you won’t be printing for a long time, do not turn off the printer (some models automatically clean the printhead).

b. Cleaning the Printhead

• Use the Head Cleaning / Deep Cleaning option in the printer software.

• Never touch the printhead directly with a dry cloth or alcohol.

c. Using High-Quality Ink

• Counterfeit or low-quality ink can cause:

  • Clogged printheads

  • Sensor damage

  • Reduced print quality

2. Software Maintenance (to preserve settings and stored data)
a. Saving Printer Settings

• In Windows: use Export Printer Settings.

• On industrial models, use the device menu: Backup → Save Config.

• Store the settings file on a USB or computer for future recovery.

b. Updating Software and Drivers

• Every few months, update from the manufacturer’s website:

  • Firmware

  • Driver

  • Software Utility

• This prevents software errors and settings loss.

3. Physical and Environmental Maintenance
a. Temperature and Humidity

• Temperature: 18–25°C

• Humidity: 40–60%

  • Too dry → ink dries

  • Too humid → board damage

b. Dust Control

• Clean the area around the paper feed weekly using compressed air or a lint-free cloth.

c. Proper Placement

• Avoid placing the printer near windows, direct sunlight, or heating devices.

4. Paper and Feed Path Maintenance

• Use high-quality, dry paper.

• Keep paper in its cover to prevent moisture absorption.

• Clean the paper feed path monthly.

5. Preventing Common Problems
a. Clogged Nozzles

• Regular test prints

• Proper ink storage

• Avoid low-quality ink

b. Storage or Settings Errors

• Backup settings regularly

• Avoid sudden power-offs

• Keep software up to date
