SM 52 blowers not turning off.

This is on a 1996 sm 52-2 without console.

Earlier this year, early summer when starting to warm up, I noticed the deliver blowers ( slow down, down blowers, decurler, and the blower at the front of the register convayor) will not shut off. I wanna say they used to operate together with the feed blowers and suction. Any thoughts anyone?

 

If you face once again to this problem, do the followings:

- all of the blowers you mentioned, are turning ON/OFF by 15K73M. while the feeder stops and the last paper drops into the delivery, they turn OFF. you have to check after the feeder compressor turned OFF, 15K73M should disengage and all the blowers should turn OFF as well.

- when you are complaining about excess temperature, open the main cabin door carefully and check if you face this problem or not.

- After all, ZSK could be defective.

Good lock,

You got it!!! I turned on then off the relay labled k73m. Now it is working properly again. thanks
