Troubleshooting and Repairing Spongeless Refillable Cartridges for Canon 240/241: A Step-by-Step Guide

Welcome to our comprehensive guide on troubleshooting and repairing Spongeless Refillable Cartridges for Canon 240/241. In this video, we will address some common issues that users may encounter with these cartridges and provide practical solutions. Make sure to watch the accompanying video for detailed instructions on each step. Let's dive in!

One of the most common problems users face is when they forget to glue the middle part of the color cartridge, resulting in color mixing and the black color not appearing. To rectify this issue, it is crucial to ensure the middle part of the color cartridge is securely glued. If you purchased the kit from BCH Technologies, they provide a mod kit specifically designed for spongeless cartridges, which can assist in resolving this problem.

To begin, it is important to protect the cartridge printhead. Place the first piece with the non-glued part facing the printhead air and the glued part towards you, ensuring the sticky part is not in contact with the top of the printhead. Next, apply the second piece with the glued part facing down, ensuring it sticks firmly to the cartridge.

For added protection, use a third piece that overlaps the underneath piece. This prevents any super glue from dripping onto the electronic ribbon, as the tapes act as a barrier. If needed, use multiple pieces of tape to ensure a secure seal. Take extra care during this step to prevent any glue from coming into contact with the printhead.

Once the cartridges are properly sealed, it is necessary to sand down the color cap to ensure an even surface. This step is crucial for creating an airtight seal when the cover is placed on the cartridge. Use a gel-type super glue to attach the cover, applying enough glue to ensure a secure bond. Leave the cartridge undisturbed for at least 12 hours to allow the glue to cure properly.

Pay special attention to gluing the middle T section, as this is a critical step that cannot be fixed later. Apply extra glue to reinforce the cover and press it down firmly, ensuring an airtight seal. If any gaps are present, additional glue can be applied around the edges. Use the end of the glue tube to sculpt and push the gel into the gaps between the cover and the base of the cartridge.

To test the airtightness of the cartridge, gently blow air into it. There should be no air escaping from the top border, indicating a successful seal. However, air bubbles should be visible coming from the bottom of the cartridge, specifically from the printhead. If any color is clogged, it will require unclogging using appropriate methods.

In some cases, users may encounter error codes, such as "E-05," when using modified non-virgin cartridges. Non-virgin cartridges are those that have been refilled and sold to refill companies after being discarded. These cartridges typically have an additional chip glued on top of the original chip. If the added chip is defective, it can cause errors. However, in some instances, it is possible to peel off the added chip and expose the original chip underneath, giving the cartridge a second life.

During the testing process, it is crucial to identify any leaks and address them promptly. If any color nozzles are clogged, a combination of soaking and blowing air can often help resolve the issue. However, if the magenta nozzles are severely worn out, it may be necessary to replace the entire cartridge.

In the event that a cartridge proves unrepairable, it is recommended to provide a replacement unit to the customer. Communicate clearly about the issue and offer suitable alternatives to ensure customer satisfaction.
