How to Fix Magenta and Yellow Ink Issues on Epson WF-3540

Question:

My Epson WF-3540 printer is not printing the magenta and yellow colors. At first I deep cleaned the printheads, this helped a little but not solve the issue completely. I also put the print head in cleaning fluid, with little results. However, a printer repair shop told him it could be because of the pump head assembly or the inkjet cartridge gasket seals. Does this seem right to you? I also have an extra WF-3540, however I need to find a head and cable bundle from an FTC printer. Could you tell me where I can get one of these?

To answer your question, your Epson WF-3540 experiencing magenta and yellow ink issues can be attributed to several factors, if you don't mind. Let's break down the potential causes and troubleshooting steps in detail.

Possible Causes for Magenta and Yellow Ink Issues

Clogged Printhead

You’ve already tried cleaning the printhead, which is the first logical step. Sometimes, even after manual cleaning or using a soaking method, the problem persists. This is because dried ink can cause the ink passages to become deeply clogged, making it harder for regular cleaning fluids to clear them.

Pump Head Assembly

The repair shop’s suggestion that the pump head assembly could be the problem is valid. The pump head assembly draws ink from the cartridges and ensures it flows smoothly to the printhead. If this component malfunctions or becomes clogged, the printer might struggle to deliver ink, particularly for specific colors like magenta and yellow.

Cartridge Gasket Seals

Another plausible issue is the gasket seals of the inkjet cartridges. These seals ensure ink is transferred correctly to the printer’s internal ink system. Over time, these seals can wear out or become damaged, leading to inconsistent ink flow, especially if you’re using aftermarket cartridges. Checking and possibly replacing the cartridge seals might solve the problem.

Step-by-Step Troubleshooting

Step 1: Perform a Deep Printhead Cleaning

If your manual cleaning didn’t yield significant results, try using a professional-grade printhead cleaning kit designed for Epson printers. These kits often have more robust cleaning solutions that are better at dissolving dried ink. Be sure to follow the instructions carefully to avoid damaging the printhead further.

Step 2: Inspect the Pump Head Assembly

Could you check the pump head assembly for any visible blockages or wear? If you have experience with printer repair, you can disassemble and clean this part. Ensure the pump mechanism works properly and is not obstructed by dried ink or other debris. If you're unsure about this process, consider consulting a professional for assistance.

Step 3: Check the Cartridge Seals

Inspect the ink cartridges, especially the magenta and yellow ones, for any damage to the gasket seals. If you notice that the seals are worn or the cartridges are not sitting properly in their slots, replace them. Using OEM cartridges may also help ensure better compatibility and ink flow.

Step 4: Consider Replacing the Printhead

If cleaning the printhead and pump head assembly doesn’t solve the issue, the printhead itself might be the problem. Printheads can become irreversibly clogged or damaged over time. Since you mentioned you have a spare WF-3540, you may want to try swapping the printhead from the spare unit.

Locating an FTC Printer Head Cable Bundle

As for the FTC printer head cable bundle for your spare WF-3540, these can be tricky to find since Epson tends to keep specific replacement parts in limited stock. However, you can often source these from third-party sellers or specialty electronics suppliers. Here are some options for finding the cable bundle:

AliExpress: This site often carries a wide range of Epson parts, including specialized cables.

eBay: Many repair shops list parts like printhead cables on eBay.

Printer Repair Shops: Some shops may sell parts from printers they no longer repair.

Before purchasing, verify that the cable bundle is compatible with your specific printer model (WF-3540).
