Envelope Feeder Service Source
The Envelope Feeder volume of Apple's Service Source is Apple's 50-page service manual for the envelope feeders of the LaserWriter Pro 600/630 and LaserWriter 16/600 PS laser printers. It covers only Take Apart, Additional Procedures and Adjustments for the feeder; Apple refers to the main printer manuals for everything else.[1]
Contents
[edit | edit source]Page numbers are PDF pages.[1]
- Basics (pp. 3–7): about this manual; compatibility (p. 4); slip torque rollers (p. 6).
- Take Apart (pp. 9–42): envelope weight, left, right, front and bottom covers, motor, sensing arm, controller board, printer interface cable, pickup rollers, transfer drive assembly, separation drive assembly, primary feed roller, secondary feed roller.
- Exploded view (p. 44), naming the parts without part numbers.
- Additional Procedures (pp. 46–47): expansion post connectors.
- Adjustments (pp. 49–50): separation guide opening.
Two feeders
[edit | edit source]The LaserWriter Pro 600/630 envelope feeder works only with the Pro 600/630. The LaserWriter 16/600 PS envelope feeder works with either printer. Apple gives three ways to tell them apart (pp. 4–5):[1]
| Check | Pro 600/630 feeder | 16/600 PS feeder |
|---|---|---|
| Pickup rollers and shafts | Two-piece roller and shaft | One-piece roller and shaft |
| Vendor number on the end of the controller board | RG5-0576 | RG1-3437 |
| Serial number | Starting JXC00001 | Starting LBK00001 |
Notes from the manual
[edit | edit source]- Slip torque rollers and gears are ratcheted, torque-limiting parts that use bearings instead of teeth. The primary feed roller turns independently of its shaft in reverse, so jams can be pulled out; the separation drive's one passive gear and two slip torque gears make the separation rollers counter-rotate whichever way the gear train is driven; and the two pickup roller shaft gears that mesh with the transfer drive are slip torque gears. A roller that turns freely one way is therefore not necessarily faulty.[1]
- Separation guide opening: if the separation guide plate has been removed from the front cover, loosen its screw, put a 1 mm and a 0.5 mm thickness gauge together (1.5 mm) between the plate and the primary feed roller, and tighten the screw (pp. 49–50).[1]
- Cable receptacles are held by finned expansion post connectors that can be hard to remove; Apple suggests fingers, small bent-nose pliers, grip rings forced round the post, or a 5 mm nut driver (pp. 46–47).[1]
What this manual does not contain
