Memory and Security Key

CAUTION
To prevent electrostatic damage to electronic components, always wear
a grounded static wrist strap when you handle memory modules.
Removal
1. Make a configuration printout of all saved configurations. (Refer to the
User's Manual.)
2. Prepare the printer for maintenance (page 230).
3. Cabinet Models: Remove the paper path (page 303).
Pedestal Models: Remove the top cover assembly (page 281).
4. Put on a static wrist strap and ground the lead to an unpainted part of the
printer frame. Touch the printer frame with the hand wearing the wrist
strap before you touch memory modules or the controller board
5. To remove the flash SIMM or SDRAM DIMM (V5 controller only), gently
open the side locks, angle the memory module upward, and remove it
from the socket. (SDRAM is soldered on V6 controllers and cannot be
removed.) (See Figure 33, page 298.)
6. If you need to remove the security key, gently lift the locking tab on the
top side of controller board connector J9 enough to release the key, then
lift and remove the security key. (See Figure 33, page 298.)
NOTE: The security key is a 3-pin semi-programmable EEPROM that
enables the loading of microcode and emulation software. The printer
will not operate correctly without a security key. If you need to replace
the security key, contact Printronix for a replacement.
Installation
1. Put on a static wrist strap and ground the lead to an unpainted part of the
printer frame. Touch the printer frame with the hand wearing the wrist
strap before you touch memory modules or the controller board.
2. If you removed the security key, position it on controller board connector
J9 so that the lock indentation is on the same side as the locking tab on
connector J9. Gently press the security key down onto the pins until the
locking tab engages the lock indentation and locks the key in place. (See
Figure 33.)
NOTE: Installing flash memory from one controller board to another does not
transfer all operating system software, so you must download the
emulation again.
3. Insert the memory module at a 45 degree angle into the correct socket
(see Figure 33) on the controller board:
a. Insert the flash SIMM in socket J11 on the controller board at a 45
degree angle. Position the flash SIMM with the notched end toward
the right side of the controller board. Press the SIMM gently into the
socket until the edge connectors are seated, then press the SIMM
downward until the side latches lock the SIMM is place. (See
Figure 33, page 298.)
