5) Cleaning the floppy disk drive
If foreign particles adhere on the head of the floppy disk drive, an error may occur when reading or saving data on
the floppy disk.
When reading or saving the data on the floppy disk cannot be done normally, clean the floppy disk drive using a
cleaning disk. The cleaning disk which is sold by the shops handling the personal computer needs to be purchased
by the customer.
Although the cleaning frequency differs depending on the drive use and environment, the cleaning needs to be done
every 6 months.
<Procedures>
1. Set the cleaning disk into the floppy disk drive.
2. Push the data reading button.
3. When an error message "DISK IS NOT FORMATTED PRESS ESC KEY" appears, the cleaning is finished.
Push the reset button to cancel the error.
4. After checking that the access lamp of the floppy disk drive is OFF, take out the cleaning disk.
(Note) The cleaning time is listed on the cleaning disk. Measure the time until the error message is displayed.
When the time measured is shorter than the cleaning time listed, repeat this operation to approach to the
time listed.
Example) When using the cleaning disk with a cleaning time of 10 seconds
If the time until the error message is displayed is 3 seconds, repeat the cleaning operation 3
times.
<Precautions when using>
There are 2 types of cleaning disks, dry and wet. When doing the periodic maintenance, use wet type disk.
Usually dry type disk is said to shorten the floppy disk drive life as it shaves the head of the floppy disk drive. But
when the error is displayed during the normal operation even when doing the periodic maintenance, use the dry
type disk.
For the detailed information about the cleaning time and cleaning procedures, please refer to the instructions for
the cleaning disk.
[Handling of the liquid crystal display]
The liquid crystal display (LCD) is used for the message indication on the operation stand. Please be careful of the
following points.
1. Never put anything on the display surface or place strong shocks on it.
2. Due to the properties of the LCD, there may be times when an area of the LCD always lights or goes off.
(However, this does not indicate trouble.)
3. If the same message is displayed for a long period, the reflection may be slightly left on the display. If this happens,
turn the power OFF once and after a few minutes, turn the power ON again, and the display should return to the
normal condition.
