PostScript SIMM
Note
PostScript language SIMMs for the HP LaserJet 4 plus and 4M plus
printers cannot be used in the HP LaserJet 4V and 4MV printers. Only a
PostScript language SIMM designed for this printer can be used.
To verify your PostScript SIMM installation:
1 Plug in the power cord and turn the printer ON.
2 After a few seconds, the On Line light should go on and 00 READY should
appear in the control panel display. If a printer message appears instead,
see “Troubleshooting a SIMM Board” below.
3 Press [On Line] to take the printer off line.
4 Press [Menu] until PS MENU appears in the control panel display. This
indicates that your printer recognizes that the PostScript language is
installed. If PS MENU does not appear, check the SIMM installation.
5 Press [On Line] to return the printer on line.

Service / Error Messages
These messages can be generated when your printer is checking its internal
memory. (For more information on the messages below, see Chapter 8,
“Solving Printer Problems.”) They will appear in the format:
61.x SERVICE where x = 0, 1, 2, 3, or 4.
This error indicates a SIMM parity error. The x indicates which SIMM slot
generated the error. If x = 0, the slot with the defective SIMM could not be
determined. Check the HP part number to make sure you have the right
SIMM board; if you do, see the checking procedure for 61.x SERVICE and
62.x ERROR on the next page.
62.x ERROR where x = 0, 1, 2, 3, or 4.
This error indicates your printer identified a problem while checking
memory:
• If x = 0, the problem is in internal Read Only Memory (ROM); see your
HP Service Representative.
• If x = 1, 2, 3, or 4, the problem is in SIMM slot 1, 2, 3, or 4.
