PIXMA TS9120 printing wavy lines

DRAE — Wed, 18 Feb 2026 01:03:44 GMT

My Canon TS9100 has suddenly started printing random lines that look wavy. In fact almost look like a different font. I have deep cleaned the heads, cleaned the roller and bottom plate. I am at a loss. I am printing from the back tray and have it fully extended and wonder if this could be a cause, however I have printed from the back tray before with no problem.

Thanks for joining the conversation, DRAE!

So that the Community can help you better, we need to know exactly which Canon printer model you're using within the PIXMA TS9100 series. The model number should appear on the printer's operation panel at the lower right. That, and any other details you'd like to give will help the Community better understand your issue!

Thanks and have a great day!

Hi,

There could be ink on the encoder strip inside the printer which can impact the print quality. The encoder for this model is not accessible and would require service.

If the printer is in its 1-year warranty, I recommend reaching out to Canon support for your warranty options. You will need to register your Canon gear HERE to access additional support options.

If the printer is out of warranty, you would qualify for the Canon Upgrade program. This is for out of warranty units which have been diagnosed to require service or are incompatible with a new or upgraded system. This program allows you the opportunity to purchase a replacement product discounted from the list price. Free ground shipping is included with your purchase.

You can take advantage of this offer by calling the Canon Sales Department at (866) 443-8002 Mon-Sat, 9 AM to 9pm EST excluding holidays.
