							Checking DIMM installation
Check that the DIMMs are installed correctly and working.
To check DIMM installation
1. Turn the printer on. Check that the Ready light is on after the printer has completed the
startup sequence. If an error message appears, a DIMM might have been incorrectly
installed.
2.
Print a Configuration page by pressing 
 (GO) and  (CANCEL JOB) simultaneously. (A
Supplies Status page and possibly an HP Jetdirect Configuration page also print.)
3. Check the Installed Personalities and Options section on the Configuration page and
compare it with the Configuration page printed before the DIMM installation.
4. If the amount of recognized memory has not increased or the font DIMM is not
recognized, the following conditions might exist:
●The DIMM might not be installed correctly. Repeat the installation procedure.
●The DIMM might be defective. Try installing a different DIMM.
5. After you have installed the DIMM correctly, go to 
Enabling memory if you installed a
memory DIMM or 
Enabling the language-font DIMM if you installed a language-font
DIMM.
