Epson EPL-7500 - Checking the Board

The Memory Expansion Board
Checking the board
To make sure that the memory expansion board is installed
correctly and is functioning properly, turn on the printer. It will
print a start page, as described in Chapter 2.
Look at the bottom of the start page, just above EPSON EPL-7500.
You should see the following:
ramsize: 6291456
This shows that the memory board is functioning correctly. If the
ramsize number is lower than the one shown above, turn off the
power and remove the board; then reinstall it. If the ramsize
number is still incorrect, see your dealer or a qualified service
person.
