Because the A230 was slightly modified in order to develop PCB prototypes (Google: Direct Toner method / toner transfer method). And that is awarded the A230.
There are basic electrical knowledge required and the warranty is of course gone, but at 15 that is to be absorbed.
Original creates the A230 about 120-125 ° C.
By replacing the two bimetallic "KSD301 120" (ie 120 ° C) (to be adapted to the respective laser printer / toner / paper) but by KSD301 170/175/180 that here there is either Amazon or eBay, then heats the A230 far enough on in order to burn the toner on printed circuit boards. For temperatures betw. 170 to 180 ° C are necessary when using PCB-Transfer Paper (Amazon or eBay, 2 for 10p A4).
Note: In the case the KSD necessarily "NC" (normally closed), as the bimetallic course is open only on reaching the target temperature.
The original built-in thermal fuse is triggered at 198 ° C (nominal), So there is still air.
Thus, the silicone rollers to cool evenly again, I will always run after ~ 15 minutes from the A230 in cold mode.
