SYMPTOMS
On a Windows 2000-based system on which Canon printer drivers and software are installed, you may experience reduced system performance. For example, every action may take a long time to complete, or the system may stop responding (hang). When you click the Process tab in Task Manager, the MPSERVIC.EXE process may be using up to 98 percent of the system resources. Additionally, you may be unable to manually end this process.



CAUSE
This issue may occur if the Canon printer drivers or software are corrupted. The Mpservic.exe file is part of the Canon Multipass Service.



RESOLUTION
To resolve this issue, remove all Canon software. To do this:
 * 1) Click Start, and then click Control Panel.
 * 2) Double-click Add or Remove Programs.
 * 3) Select all Canon software that appears in the list, and then click Remove.
 * 4) Reinstall the software for your Canon printer.

Note: You may have to start Windows in Safe mode to successfully remove this software.
