Canon imageRUNNER 2002 is a reliable workhorse, but like any machine, it can experience issues. One frustrating problem is when the machine displays an error indicating the drum unit isn't recognized. This can bring your workflow to a standstill. This guide provides a comprehensive solution to troubleshoot and resolve this issue.
Understanding the Problem: Why Your Canon IR2002 Doesn't Recognize the Drum Unit

- Connectivity Issues: Although less common, problems with the internal connections between the drum unit and the printer's mainboard could be the root cause. Loose or damaged wiring is a possibility.
- Software Glitch: In rare cases, a software glitch within the printer's firmware could be to blame. This is less likely but still worth considering.
- Static Electricity: Sometimes, static discharge can interfere with the printer's ability to detect the drum unit.
