My machine is past warranty, so you might not want to do what I did. I’ve already gone through cleaning the case fan, and done a few modifications so that it wasn’t such a hassle the next time…and there was a next time. So I’m not nearly as reticent about opening up MCEtcher and getting my hands dirty.
I got my first air assist fan warning, right as I was trying to print the bases for a large (to me) order. I thought I knew what the air assist fan was. I was wrong. In my weekly cleanings, I’ve been cleaning the tiny fan of the bottom of the carriage plate. So when the big white button turned yellow and I saw the message, I was slightly confused because I’d cleaned it last week during the monthly deep clean. I checked there, and it didn’t look bad, but I went ahead and cleaned it again.
Tried to print again, and got the same yellow button. I actually read the entire error message this time, and went to the “clean air assist fan” page that was linked. What I thought was the air assist fan, isn’t. So I followed the instructions and found this.
Holy cow! That’s a lot of crud! So I gingerly starting cleaning. After I got all the blades cleaned, I could still see crud further down which I couldn’t clean from the top, and couldn’t even see due to the directional vent on the back. So I took the fan off the carriage plate so I could reach both sides.
That side was so grime caked I forgot to take pictures. I gingerly used the pick from my Cricut to pull out and scape away the grime from the casing on the back. And from the directional vent. And then went back and cleaned everything again.
After re-assembling the carriage plate, re-attaching the drive belt was the hardest part.
I am proud to say that MCEtcher is working like a champ again!
