How to Fix Clogged Printhead and Banding Issues on Canon TS6350

Question: How Can I Resolve Printhead Problems and Banding Issues on My Canon TS6350?

Answer:

Thank you for contacting us with your question regarding your Canon TS6350 printer. I apologize for the delay in responding, as I understand how frustrating printhead issues can be. We at BCH Technologies are committed to providing detailed and thoughtful answers to help you with your printing challenges. Your engagement, particularly with our YouTube channel ([https://youtube.com/@bchtechnologies]), is greatly appreciated and helps us improve our technical expertise.
Now, let’s address your issue with clogged printheads and banding problems.

Observations from the Nozzle Check

After carefully reviewing your attached scan, I noticed the following:
  1. Horizontal Banding in Yellow and Black:
    • The yellow shows slight horizontal banding, while the black has minor banding and appears a bit pale.
  2. Vertical Banding:
    • Vertical banding suggests the printhead carriage may not be seated correctly.
While your nozzle check shows better results than most printers, there is room for improvement to address these issues.

Recommended Steps

1. Switch to Dye Ink

  • If you’re currently using pigment ink, consider switching to dye ink. Dye ink tends to flow more easily and produces richer, smoother prints, which might resolve the pale black output issue.

2. Focus on Print Quality, Not Nozzle Check

  • Sometimes, the nozzle check doesn’t reflect the actual print quality. Focus on how the prints look. If they are satisfactory, the nozzle check imperfections may not matter.

3. Enable High-Resolution Printing

  • Could you turn on the high-resolution printing mode in your printer settings? This mode forces the printer to cover the same area multiple times, helping to hide minor imperfections like horizontal banding.

4. Calibrate the Printhead

  • Perform a printhead alignment from your printer’s maintenance menu. This can help resolve vertical banding caused by misalignment of the printhead carriage.

5. Use a Reliable Cleaning Solution

  • If you still suspect clogs in the printhead, a professional cleaning solution designed for Canon printers can be helpful. We recommend our BCH Cleaning Solution ([https://bchtechnologies.com]). This solution effectively dissolves dried ink and improves ink flow.
  • You can use an unclogging tool kit, including a syringe and tube, to manually flush the printhead nozzles with a cleaning solution.

6. Focus on Printing Regularly

  • Regular use of the printer is essential to prevent future clogs. If you leave the printer idle for extended periods, consider printing a simple test page once a week to keep the ink flowing smoothly.

Addressing Banding and Print Quality Issues

For horizontal banding, ensure the following:
  • The printer is on a stable surface to prevent vibrations.
  • The paper type selected in the print settings matches the paper loaded in the printer.
For vertical banding, double-check the printhead seating and alignment. Even slight misalignments can cause visible imperfections.

Important Note

Addressing printer issues can be complicated due to the hands-on nature of the problems. Therefore, we cannot provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service).
Our services are structured to repair either a whole printer or specific parts. If you opt for mail-in or local drop-off services, we provide clear instructions on how to proceed. However, we acknowledge that our rates could be more economical. Thus, we highly recommend exploring self-help options like online research and video tutorials.
You can start by visiting our YouTube channel homepage ([https://youtube.com/@bchtechnologies]) and using the search icon next to "About" to find relevant videos. With over nine years of content, it’s the most efficient way to locate helpful resources.
 
Thank you again for reaching out. I hope these suggestions help resolve your printhead and banding issues. If you have further questions or updates, don’t hesitate to contact us—we’re here to help!
