Since I don't think this is documented on the site yet, here's the list of caps for both the logic and power supply boards on the StyleWriter 2400 printer. In my case they were all fine, so I ended up not replacing anything, but good to have the reference if something fails in the future. All caps are radial through-hole aluminum electrolytic.
Logic Board
| Location | Capacitance | Voltage | Diameter (approx.) | Height (approx) |
| C15 | 2,200uF | 35V | 18.5mm | 21mm |
| C18, C66 | 100uF | 35V | 6.5mm | 12mm |
| C29, C208, C209 | 100uF | 10V | 8mm | 9mm |
Power Supply Board
| C009 | 330uF | 200V | 25mm | 30mm |
| C101 | 820uF | 35V | 13mm | 25mm |
| C102 | 470uF | 16V | 10mm | 16.5mm |
| C103, C104 | 0.47uF | 50V | 5mm | 12mm |
| C105 | 47uF | 35V | 6.5mm | 12mm |
| C106 | 4.7uF | 10V | 5mm | 12mm |
