Introduction
This manual describes solutions for problems that may occur during operation of the Aquilion 32 system. Problems
are sorted into various categories. Find the section that applies to your problem, and take the actions described in
that section.
Contact your Toshiba service representative if you are unable to solve a problem despite taking the actions described
in this manual, or if the problem you have is not covered in this manual.
In some cases, when an error message is displayed, a combination of the [DETAIL] button and the [XC REST] or [OK]
button is displayed in the error message window. In such cases, click the [DETAIL] button first. The contents of the
error are logged in the system and the error details are displayed. Then, press the [XC RESET] or [OK] button.

Procedures for [Reset Scansys] and [Reset System]
The solutions instruct that [Reset Scansys] or [Reset System] is to be performed in some cases. The procedures for
them are as follows.
1. Move the mouse cursor to the upper left of the monitor screen and leave it for 5 seconds or longer.
2. The following window surrounded by a white border is displayed in the center part of the monitor.

Reset Window
Reset Scansys
Reset System
Reset Film Que
Film Que Clear

3. Hover the mouse cursor (x) over [Reset Scansys] or [Reset System] and wait for a few seconds. The reset
function should start.

Times required for system shutdown, reboot, and reset

The times required for system shutdown, reboot, and reset are as follows.
Shutdown about 2 minutes
Reboot about 5 minutes and 50 seconds
Reset Scansys about 4 minutes and 40 seconds (scan monitor side)
about 1 minute and 40 seconds (image processing monitor side)
Reset System about 4 minutes and 40 seconds (scan monitor side)
