Maintenance Guide for Jet Printer Enclosure

---

1. Standard Environmental Conditions

a. Temperature

• Maintain 18–25°C.

• Avoid temperature fluctuations (no direct heating or cooling).

b. Humidity

• Maintain 40–60%.

• Below 30% → printhead and ink may dry out.

• Above 65% → board damage and paper jams may occur.

c. Ventilation

• Ensure gentle, uniform airflow.

• Use a quiet fan with a dust filter.

• Air should not blow directly onto the printer.

2. Interior of the Enclosure

a. Printer Placement

• Place the printer on a stable, flat, vibration-free surface.

• Recommended clearances:

  • Rear: 10–15 cm

  • Sides: 20 cm

  • Top: 30 cm

b. Surface Material

• The floor or table should not absorb moisture.

• Preferably use laminated MDF or painted metal.

c. Lighting

• Indirect light, no direct sunlight.

• If there’s a window → install curtains or a UV filter.

3. Dust Control

a. Air Intake Filter

• Use a simple HEPA or mesh filter at the air intake.

• Clean or replace every 1–2 months.

b. Weekly Cleaning

• Wipe around the printer with a lint-free cloth and use compressed air.

• Vacuum the floor once a week.

4. Security and Data Protection

a. Power Protection

• Use a small UPS (500–800 VA) to prevent:

  • Sudden power-offs

  • Damage to stored settings

b. Electronics Ventilation

• Overheating can erase some settings in certain models.

5. Consumables Storage in the Enclosure

a. Cartridges and Extra Ink

• Store in a closed cabinet, away from light.

• Temperature: 18–25°C

• Store upright, not lying down.

b. Paper

• Keep paper in its original plastic cover.

• Moisture absorption can cause jams and blurred printing.

6. Standards for Industrial Jet Printers (CIJ / TIJ)

• Enclosure air should be free of solvent vapors.

• Ventilation should maintain balanced pressure to prevent solvent odor spread.

• For CIJ printers, a stable temperature of 20–22°C is optimal.
