Epson 900 - Manual (Page 30)

Using Diskettes
You can use either 720KB double-density or
1.44MB high-density, double-sided diskettes in
your 35-inch, 1.44MB diskette drive.
To insert a diskette, hold it with the label
facing up and the shutter leading into the
drive. Slide it all the way into the drive.
To remove the diskette, make sure the diskette
drive light is off. Then press the release button
and pull out the diskette.
CAUTION
Never remove a diskette or reset or turn off the
computer while the diskette drive is being accessed;
you could lose data. Also, be sure to remove the
diskette before you turn off the computer.
