What is a Continuous Ink Supply System (CISS)?

A Continuous Ink Supply System, commonly referred to as a CISS, is a cost-effective solution designed to provide a continuous flow of ink to your printer’s cartridges. Instead of using traditional ink cartridges, a CISS consists of large ink tanks connected to the printer by a series of flexible hoses. This system allows you to print without worrying about running out of ink, making it a convenient and economical option for high-volume printing.

Advantages of using a CISS with the Epson L120:

  1. Cost savings: CISS significantly reduces the cost of printing by allowing you to purchase ink in bulk, which is more affordable than individual cartridges.
  2. Continuous printing: With a CISS, you can print continuously without interruptions due to empty cartridges.
  3. Reduced environmental impact: CISS reduces the number of disposable cartridges, which is better for the environment.

Installing CISS with the Epson L120

Before installing a CISS, make sure you have all of the necessary components included in the CISS kit. This typically includes ink tanks, tubing, connectors, and detailed instructions. Follow the steps below to install a CISS on your Epson L120:

  1. Prepare the printer: Turn off the Epson L120 and unplug the power cord. Next, Open the printer cover to access the cartridges.
  2. Remove the existing cartridges: Carefully remove the original ink cartridges from the printer.
  3. Install the CISS cartridges: Insert the CISS cartridges that came with your kit into the cartridge slots in the printer. Make sure they are securely seated.
  4. Connect the hoses: Attach the flexible tubes from the CISS kit to the cartridges. Each tube corresponds to a specific color (for example, black, cyan, magenta, yellow). Make sure the tubes are securely connected and free of kinks or bends.
  5. Secure the ink tanks: Position the ink tanks near the printer, making sure they are level with or slightly above the printer to allow gravity to help the ink flow. Attach the tubes from the cartridges to the appropriate color-coded ink tanks.
  6. Prime the CISS: Follow the manufacturer’s instructions to prime the CISS system, which involves filling the ink lines and cartridges with ink. Typically, this is, done using a supplied syringe or other priming tool.

Using the Epson L120 with CISS:

Once you have successfully installed the CISS, you can use your Epson L120 as usual, with a few additional considerations:

  1. Check ink levels: Check the ink levels in the external ink tanks regularly. Refill them as needed to ensure a continuous supply of ink.
  2. Print regularly: To keep the ink in the tubes from drying out, it’s important to print regularly. Even a small test print once a week can help maintain ink flow.
  3. Maintain CISS: Clean the print heads and tubes regularly to prevent clogging and maintain consistent print quality.
  4. Buy quality ink: To avoid problems such as clogging or fading, use high-quality ink that is, compatible with your CISS system.
