Troubleshooting
Your printer is a reliable, precisioned instrument and should not cause you any trouble if
it is used and treated sensibly. However, we are providing you with this troubleshooting
section to help you should you encounter any problems with your printer. Remember
that your printer is a highly sophisticated device and that this section is intended to be
only a brief guide. As with many other precisioned instruments, this printer contains
high voltage. We request that you perform only the operations which are explained here.
Warning: Any attempt to perform troubleshooting operations other than those
described here may result in electric shock, damage to the printer or
both.
The following table is provided to give you an idea of where to find solutions to prob-
lems you may encounter.
