Envelope Feeder

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:

1By 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.

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.

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.
