(3) 
Place the 9816 on a flat surface and lay it on its right side.  Remove the two (2) Phillips-
head screws that hold the front panel to the top rail and the two (2) Allen-head screws 
that hold the front panel to the bottom rail.  (Note, the bottom Allen-head screws also 
attach the push-pull handle to the front panel.) 
 
 
(4) 
Slide the front panel forward as far as it will go (approximately 3/8".) 
 
 
(5) 
Remove the two (2) 4-40 x 1/2" Phillips-head screws and remove the PC-295 board and 
its associated LED indicators.  For QDC-tubed scanners, the large network resister on 
the PC-295 board will be on the ‘up’ side of the board.  If your scanner is front-tubed, with 
compression fittings, the network resistor will be on the left side of the board.  Also, front-
tubed scanners with compression fittings use longer LED connectors as well as 
standoffs.  A simple way to remember which way the board mounts is that the PWR LED 
is green and the BSY LED is red. 
 
 
(6) 
Perform whatever maintenance or replacement is required.  If the entire PC-295 board is 
to be replaced, cut the plastic ties that holds the ribbon cable to the front panel and the 
bottom rail.  Reinstall the two (2) Phillips-head mounting screws (together with the 
standoffs, if required), and re-assemble the front panel. 
 
 
(7) 
Reconnect the PC-295 board cable to P13 on the PC-299 board, install new plastic ties 
(that hold the PC-295 ribbon cable to the front panel and the bottom rail), replace the side 
cover(s), replace the scanner into the 98RK-1 Scanner Interface Rack, tighten the 
locking rod, and test your scanner to ensure proper operation.
