🧰 Regular Maintenance Checklist

Like any precision tool, your poster printer machine benefits from regular upkeep. Here’s a basic weekly/monthly checklist to follow:

• ✅ Print a test page weekly to prevent ink from drying out.
• ✅ Check ink levels and refill or replace cartridges before they run dry.
• ✅ Inspect rollers and feed mechanisms for dust or debris.
• ✅ Update printer firmware/software to ensure compatibility and fix bugs.

• ✅ Run cleaning cycles if print quality starts to drop.

Tip: Set calendar reminders for maintenance tasks so they don’t get overlooked.

🧼 Cleaning and Calibration Guides

1. Cleaning Inkjet Printer Heads

Over time, ink residue can clog nozzles, causing streaks, color banding, or faded prints.

Manual Cleaning:

• Use your printer’s built-in cleaning utility (found in printer settings).
• For stubborn clogs, remove the cartridge and use a lint-free cloth dampened with distilled water to gently wipe the printhead.
• Never use tap water—it can leave mineral deposits.

Deep Cleaning Tip: If the built-in tool doesn’t work after 2–3 attempts, consider using a specialized printhead cleaning kit.

2. Calibrating Your Printer

Calibrate your printer every few weeks or after installing a new cartridge or driver.

• Use the printer’s color calibration tool or install ICC profiles for your paper type.
• Adjust alignment settings to prevent ghosting or misregistration.
• Some high-end printers offer auto-calibration—use it!
