Compatibility
Note: The LaserWriter Pro 600/630 feeder is not
compatible with the LaserWriter Pro 16/600 PS printer,
but the LaserWriter Pro 16/600 PS feeder is compatible
with the LaserWriter Pro 600/630 printer. Unless noted
otherwise, all parts and procedures contained in this manual
do apply to both versions.
You can tell the two feeders apart in two distinct ways:
1 By comparing controller board serial numbers: The
LaserWriter Pro 600/630 sheet feeder controller
board has the vendor number "RG5-0541" imprinted on
it. The LaserWriter 16/600 PS sheet feeder controller
board bears the number "RG5-1086."
2 By comparing serial numbers: Numbers starting with
JBD00001 denote feeders for use only with the Pro
Basics Compatibility - 3
600/630. Numbers starting with LBJ00001 denote
feeders for use on both generations of printer.
