Verifying DIMM Installation
To verify that the DIMM installation was successful, print out a
configuration page (see the chapter on using the printer control
panel). If the DIMM has been installed properly, the figure in the
Memory section of the configuration page will reflect the new total
amount of memory.
If the printer control panel displays an error message, see chapter 8
for descriptions of printer control panel messages.
