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.
|
||
|
||
