PRINTER MAINTENANCE
Cleaning the diskette drive
The diskette drive should be cleaned once each month. To clean
it, you must have the cleaning kit. This kit contains two cleaning
disks for double-sided diskette drives and a bottle of solution.
1. Make sure the system is powered on.
There must be power to the diskette drive to perform this
procedure.
2. Apply a small amount of the cleaning solution to the cleaning
disk. Apply just enough solution to saturate the area
exposed in each of the two large cutouts.
3. Insert the prepared cleaning disk, label side up, into the
diskette drive until the jacket is solidly against the stops, just
as you would insert a diskette.
4. Move the drive lever into the closed position (clockwise) and
allow the diskette drive to run for at least 30 seconds.
CAUTION: You may run the cleaning disk for more than 30
seconds, but never more than 5 minutes. Excessive use
causes premature wear to the heads.
5. Move the drive lever to the open position
(counterclockwise).
6. Remove the cleaning disk.
