MG7720 misalignment, printing blurry

[luenceles]

Hi, I have tried auto-deep cleaning several times for my MG7720. The attachment shows how PGBK patterns are misaligned. Does anyone know what I should do to fix this? Everything printed in black will be blurry, like there's a shadow for each character.

I am also experiencing these exact same issues for the last couple years now. I've tried everything, print head alignments (auto and manual), countless cleanings (regular and deep), etc. It says my firmware is the latest. I'm out of ideas. My husband wants to get rid of it. but I love my printer and would much rather fix the issue. Hopefully someone can help 🖨

Hi luenceles,

Blurry printing can be caused when the encoder/timing strip inside your PIXMA MG7720 is smudged.

Cleaning this will resolve the issue.

To clean the encoder/timing strip, please follow the steps in this Knowledgebase Article:

Hi I tried to clean the encoder timing strip. However, it got a B203 error after I cleaned it. Is there a way to resolve this? I only clear the plastic strip with the alcohol

How is everything now?

To resolve the issue with the misaligned black patterns on your Canon MG7720, start by performing a manual print head alignment through the printer settings. If that doesn't work, try running a manual head cleaning. Also, check whether the black ink cartridge is low on ink or dried out. Additionally, utilize the printer’s diagnostic tool for clogged nozzles. If the problem persists, consider contacting Canon support. When I was a student, my teacher assigned me a dissertation on research papers, but I couldn't complete it on my own. My brother recommended a website called, academized.com Academized. I had a positive experience using their service. It was life-changing for me. The professional writers at Academized delivered high-quality, AI-free content. They offer dissertation writing, research papers, and various other academic services for students. I plan to use their service for all my future educational dissertations.

Cleaning the encoder strip did not help my printer.

Please try cleaning the encoder again.  Please make sure to clean the whole strip, from extreme left to right.
