Epson EQUITY Y14499113001 - Manual (Page 119)

Check that your printer is connected to the computer, and that it is turned
on, loaded with paper, and on-line. Press Y and then Enter to continue, or
press N and Enter to return to the menu.
When you continue the test, the computer checks that the printer is
responding correctly. This test detects whether the printer is off-line or
whether an interface error exists. If no errors occur, the computer sends a
repeating sequence of ASCII h
c aracters and bit-image data to the printer
until you press any key. The pattern looks like this:
Text data
data
The text data. includes all the characters commonly used by programs
that require foreign languages or graphic characters. If your printer prints
different characters than you see in the illustration, you may need to take
care with certain software. The bit-image data is sent to the printer using a
command (ESC K) compatible with Epson and IBM printers. If this pattern
is printed correctly, you can use the MS-DOS GRAPHICS program to print
out copies of graphics screens.
Note: Even if the test runs only for a short time, your printer may store
many characters in its buffer. To stop printing, turn the printer
off-line.
Hard Disk Drives and Controller Check
Use this option to test the performance of the hard disk drives installed
in your computer. If any errors occur, have the drive checked and serviced by
your dealer.
