Caution
When removing a board from the antistatic
package, avoid touching the metal traces on the
SIMM board.
For memory boards, compare the part number on the outside of
the package to the part number in the table below. If you have
not received the correct board, notify your authorized
Hewlett-Packard dealer immediately.
The LaserJet 4 Plus Optional Memory (C3130A, C3131A,
C3132A, C3133A, or C3146A) is not compatible with the HP
LaserJet 4. If the LaserJet 4 Plus Optional Memory is installed
in the LaserJet 4, the printer will display a “53.1X.08 ERROR” (X
indicates the position of the SIMMs slot).
