HP LaserJet 6pmp Printer series - Manual (Page 129)

Checking SIMM Installation
Follow this procedure to verify that the SIMM is installed correctly:
1 The printer should return to a ready state when it is turned on (Ready
light on). If the Error (back) light comes on, the SIMM may have been
installed wrong. Check the error messages starting on page 5-12.
2 Print a self test by simultaneously pressing [Go] and [Job[Cancel] .
3 If you installed a memory SIMM, check the memory section on the self
test and compare it with the self test printed previous to the SIMM
installation. The new self test should include the new memory.
4 If you installed a printer language/personality such as PostScript SIMM,
check the Personalities section on the self test. This area should list the
new printer language/personality.
