StyleWriter Capacitor List

Posted by: elemenoh on 2020-03-13 21:24:23 I have a StyleWriter that would power up for a couple of seconds and then power off. Tearing it apart revealed leaking caps on the logic board. Here's a map and Digikey cart in case it's helpful to others. https://www.digikey.com/short/z829n5 In my case, the 100µF caps looked worst and I happened to have them on hand. After replacing them, the printer powered up okay.

Posted by: demik on 2020-05-25 10:44:29 Well mine didn't have that luck. Got it in a lot and "does not power up". The StyleWriter was shorting the PSU. Tried with a 19V Dell PSU and same issue. Opened the beast and caps were as bad as @GregorHouse. But mine corroded the board somewhat, I had a few vias and traces ripped top and bottom. The board was always shorting the PSU with no obvious shorts in the board. Tried replacing caps, even without removing caps, tested diodes, not any better. I think one of the chips is shorting the PSU, didn't managed to find the right one. Dediced with some regrets to recycle the printer and found this... A corroded and seized motor. Part of the frame was rusted too. Looks like the printer got liquid in it by the previous owner. That would "explain" the PSU shorts... Anyway thanks @elemenoh, you saved me a few hours! And my Mac Plus now have an Apple Logo. It's the same size 🙂

Posted by: rollmastr on 2021-09-29 03:13:19 I thought I might add some info on the Rev 2.0 StyleWriter as it uses a slightly different PCB... C10 - 25V 1000µF C11 - 35V 2200µF C3 - 25V 3300µF C2 - 25V 3300µF C410 - 10V 100µF C4 - 10V 100µF C5 - 50V 1µF C6 - 50V 1µF C7 - 50V 1µF C12 - 50V 0.47µF Keep in mind that you will need low profile caps for C2, C3 and C11. I had to reuse the old ones. /edit: just to clarify, this is an original StyleWriter with ROM Rev 2.0, not a StyleWriter II.
