Epson 10020 - Manual (Page 121)

Note
If your application program requires a monitor that
supports graphics but you have a monochrome monitor,
the results will be unpredictable.
7. If you are still having difficulty with your monitor, try
running either the Monochrome Display Adapter and CRT
Check or the Color Graphics Display Adapter and CRT
Check, both of which are described in Appendix D of this
manual. If the diagnostics program indicates an error,
contact the place where you bought the monitor. If you are
using an Apex monitor, call your Epson Customer Care
Center for assistance.
Diskette Problems
If you have trouble accessing data on a diskette, try the
following steps:
1. Is the diskette inserted properly? You may have inserted it
upside-down or it may not be inserted all the way. Remove
the diskette from the diskette drive and reinsert it with the
label facing up and the read/write slot leading into the
drive. (See Chapter 2 for detailed instructions on inserting
and removing diskettes.)
2. If reinserting the diskette does not solve the problem and
you have access to another diskette drive of the same type,
place the diskette in the other drive and repeat the
operation. If you can successfully repeat the operation in
the new drive, the trouble may be in your diskette drive.
See the section below on “Diskette Drive Problems.”
3. If the problem persists in the new diskette drive, make sure
the diskette is the correct type for your drive. The 360KB
drive in your computer uses 5 1/4-inch double-sided,
double-density diskettes. You cannot use diskettes
formatted for 1.2MB in this drive.
