TURBOLASER/PS EL/LPC UPGRADE KIT
|
|
PART NUMBER 500477-001
|
|
|
|
|
|
|
|
PROBLEM DESCRIPTION
|
|
|
|
The original Video Cable PN 220260-001 supplied with the
|
|
TurboLaser/PS Printer connecting the PostScript board to the
|
|
Ricoh Engine Video board contains a plastic plug in pin #5. This
|
|
plug mates with the clipped pin on J-4 of the Postscript board.
|
|
This plug interferes with the re-installation of the cable to J-2
|
|
of the new Interface Mux board J-2 connector. J-2 does not have
|
|
pin #5 clipped.
|
|
|
|
SOLUTION
|
|
|
|
Simply remove the plug from pin #5 of the Video Cable. The plug
|
|
can easily be removed with pen knife or sharp pin.
|
|
|
|
CAUTION
|
|
|
|
There are NO clipped pins on any Interface Mux board connectors.
|
|
All cables that are to be inserted into this board should be
|
|
examined for the presence of any plugs. These plugs should be
|
|
removed before attempting to insert into the Mux connectors.
|
|
Failure to remove these plugs will result in damage to the
|
|
connector pins.
|
|
|
|
UNDER NO CONDITIONS, SHOULD ANY PIN ON THE INTERFACE MUX BOARD BE
|
|
CLIPPED OR BENT TO FACILITATE THE INSTALLATION OF CABLES
|
|
|
|
|
|
NOTE: An additional Video Cable PN 220055-001 will be supplied
|
|
with all kits assembled after March 1, 1988. Instructions for
|
|
installation will be included with the modified kits.
