Diagnostic Insights from the Tech Community

In response to the user's plea for guidance, a seasoned member of the printer community, PeterBJ, offered valuable insights. PeterBJ, a Printer VIP and Platinum Printer Member with a Canon MP990, pointed out that the persistent banding issue could be due to electronic damage to the printhead. According to him, the most effective solution in such cases is to replace the printhead.

Printhead Replacement: The Only Solution

While the news may not be what users want to hear, PeterBJ emphasized that replacing the printhead is often the only way to resolve electronic damage and persistent banding issues. He strongly advised against purchasing "refurbished" printheads from online marketplaces like eBay, Amazon, Alibaba, and similar platforms. These seemingly cost-effective alternatives are, according to PeterBJ, frequently defective printheads that have been cleaned to appear new.

Choosing a Reliable Replacement

If you find yourself in a similar predicament, the next step is to source a new printhead from a reputable dealer of Canon spare parts. This ensures that you receive a genuine, reliable replacement that is free from defects. Investing in a new Canon stock printhead may be a bit more expensive, but it guarantees a long-lasting solution to your banding woes.

Taking Action

In response to PeterBJ's advice, the user expressed gratitude for the information, acknowledging that while it might not be the answer they were hoping for, it's essential to know the root cause and take the necessary steps to resolve the issue. The user committed to searching for a new Canon stock printhead and ordering it promptly.

Next Steps

If you're facing stubborn banding issues on your Canon ix6850 printer, it's crucial to go beyond the standard troubleshooting steps. Electronic damage to the printhead may be the culprit, necessitating a replacement. Be wary of refurbished printheads from questionable sources, as these might exacerbate the problem. Opt for a new Canon stock printhead from a reliable dealer to ensure a lasting solution.
