Solve Frequent Print Failures on Canon PIXMA TS6420a

Is your Canon PIXMA TS6420a not printing, showing as offline, or refusing to respond when you click Print? You are not alone. Many everyday Windows users run into these problems, even when the printer was working fine before. The good news is that most of these issues are caused by outdated, missing, or damaged printer software, and they can often be fixed with a simple update.

This step by step guide explains why your Canon PIXMA TS6420a may stop printing and how to fix it quickly. You will also learn the easiest way to update the printer software using DriverAssist, as well as how to update it manually through Canon’s support website and Windows Device Manager.

Let’s get your printer working again.

Why Your Canon PIXMA TS6420a Stops Printing

Your printer needs special software to communicate with your computer. Think of it as a translator. Your computer speaks one language, your printer speaks another, and this small but important program helps them understand each other.

If that software is:

• Outdated
• Missing
• Damaged
• Not installed correctly

Your Canon PIXMA TS6420a may:

• Show as offline
• Not respond when you try to print
• Print blank pages
• Print very slowly
• Display error messages
• Refuse to scan
• Disappear from your list of printers

Windows updates can sometimes replace or remove printer software. Power outages and sudden shutdowns can also damage files. Even installing a new router can interrupt communication between your computer and printer.

Updating the printer software often solves these problems because it restores the connection between your device and the Canon PIXMA TS6420a.
