How to Refill a VJ Ink Cartridge — Step-by-Step Guide for CIJ Users

VJ ink cartridges are widely used in continuous inkjet (CIJ) coding machines across food, beverage, pharmaceutical, and industrial packaging lines. Over time, refilling your VJ ink cartridge instead of replacing it can significantly reduce your running costs.

In this guide, we will walk you through the complete process of safely refilling a VJ ink cartridge, what you need to prepare, and the common mistakes to avoid.

What You Need to Prepare

Before you start, gather the following items:

1. Compatible VJ CIJ ink (make sure it matches your cartridge model)/A refillable empty ink bottle/Clean gloves to avoid contamination/A lint-free cloth for cleaning/A funnel (optional but recommended)

Step-by-Step Refilling Process

Step 1 — Power Off Your Machine

Always turn off your VJ coding machine before handling the ink cartridge. This prevents ink from leaking or being forced through the system during maintenance.

Step 2 — Remove the Cartridge Carefully

Open the machine cover and locate the ink cartridge. Gently release the cartridge from its holder, keeping it upright to avoid spills.

Step 3 — Clean the Inlet Port

Use a lint-free cloth to wipe the cartridge inlet and the connection port on the machine. This removes any dried ink residue that could cause blockages.

Step 4 — Pour the Compatible Ink

Carefully pour the compatible VJ CIJ ink into the cartridge through the refill port, using a funnel if needed. Do not overfill — leave some space at the top.

Step 5 — Reinstall the Cartridge

Place the cartridge back into its holder, ensuring it locks securely. Close the machine cover.

Step 6 — Run a Test Print

Power the machine back on and run a test print. Check that the print quality is clear and consistent. If needed, run the machine's cleaning cycle once.

Important Tips to Avoid Common Mistakes

1. Always use compatible ink that matches your specific VJ cartridge model./Never mix different brands or types of ink — this can cause clogging and poor print quality./Keep the cartridge and work area clean to prevent contamination./If the print quality is still poor after refilling, run the nozzle cleaning cycle./Dispose of empty bottles and used materials properly.

Refilling your VJ ink cartridge is a simple and cost-effective way to keep your coding machine running reliably.
