Basics Compatibility - 2
Compatibility
The LaserWriter Pro 600/630 envelope feeder is
compatible only with the Pro 600/630 printer. However,
you may use the LaserWriter 16/600 PS envelope feeder
with either the Pro 600/630 or 16/600 printers.
You can tell the two feeders apart in three distinct ways:
1 By carefully inspecting the pickup rollers and shafts:
The LaserWriter Pro 600/630 model has a two-piece
roller/shaft construction. The LaserWriter 16/600 PS
model has a one-piece roller/shaft construction.
Basics Compatibility - 3
2 By comparing controller board serial numbers: The
LaserWriter Pro 600/630 envelope feeder controller
board has the vendor number "RG5-0576" imprinted at
the end of the board. The LaserWriter 16/600 PS
envelope feeder controller board bears the number
"RG1-3437."
3 By comparing serial numbers: Numbers starting with
JXC00001 denote feeders for use only with the Pro
600/630. Numbers starting with LBK00001 denote
feeders for use on both generations of printer.

Slip torque rollers and gears
are ratcheted torquelimiting gears that use
bearings instead of teeth to
govern rotation:
Basics Slip Torque Rollers - 5
Primary Feed Roller:
This roller acts independently of the shaft when the roller is
rotated in reverse, thus permitting free removal of jams.
Separation Drive Assembly:
The gearing at the end of the separation assembly is
comprised of one passive gear and two slip torque gears.
This assembly results in counter-rotation of the separation
rollers, regardless of the drive direction of the gear train.
Pickup Roller Shafts:
The two gears that mesh with the transfer drive assembly
are slip torque gears.
