The rubber loading belt stretches and slips over time. Replace the belt (consult the exploded views section for the exact part number).
If you need to dismantle the transport mechanism, the exploded view diagrams are your safety net. They show exactly how washers, springs, gears, and chassis screws fit together, ensuring you do not have "leftover parts" during reassembly.

Dried factory grease on the sled rails or a worn drive belt.
Reference the schematic diagram in the service manual to verify the +5V, -5V, +12V, and -12V rails. Look for bulging or leaking capacitors and replace them with high-temperature (105°C) low-ESR equivalents. Advanced Calibration: RF Signal and Servo Adjustment
Before undertaking any repairs outlined in the service manual, ensure your workbench is equipped with the following specialized tools:
Dust film blocks the laser. Clean it gently with 99% isopropyl alcohol and a camera-grade micro-swab.
