Proceed as follows:
1) Tray
- Replace separation roller P/N RF5-3114 A/R.
2) Rear End Cover
- Spread the sides at the bottom a little to free two claws. Tip it up and off.
3) Upper Left Side Rail
- Two M4x10mm YZD pan head threading screws.
4) Upper Right Side Rail
- Two M4x10mm YZD pan head threading screws.
5) Top Outfeed Roller
- One e-clip at right side bearing.
- Remove gear and bearings and clean them w/Varsol.
- Clean the roller w/lacquer thinner.
- Clean pinch rollers A/R w/methyl hydrate.
- At reinstallation, apply light mineral oil sparingly to the bearings.
6) Top Cover
- Six M4x10mm YZD pan head threading screws. At reinstallation, NOTE that the four M4 screw holes nearest the corners are for the upper rails' screws.
- Two M3x6mm black pan head screws in front of and behind the exposed gears.
- One M3x6mm black pan head threading screw inboard of the exposed gears.
- CAUTION. As you lift away this cover, make sure that the pickup assembly doesn't come up with it -- that can get messy.
- Note the spring-loaded clutch lever by the upper right corner of the tray opening. Remove the lever and spring. Here's how they look when correctly in place awaiting top cover reinstallation.
7) Pickup Assembly- One two-conductor cable connection.
- Free the cable from its restraints.
- Lift out the assembly.
- EXAMINE the pickup solenoid for any tendency for its flapper to stick in the energized position. If in doubt, remove the solenoid -- it's much easier to check this with the solenoid out of the assembly. See this post.
- Replace feed roller P/N RF5-3114 A/R.
- Replace pickup rollers P/N RB1-8957 A/R. (The pickup rollers are extremely long-lasting and reliable; they seldom need to be replaced.)
8) PCA Cover
- Two claws at the top edge.
9) PCA P/N RG5-5539
- Three cable connections.
- One M4x10mm YZD pan head threading screw.
- Apply WD-40 to the pushbutton switches and actuate them many times. Blow them out w/compressed air.
10) Reassemble.
