Heidelberg SM72 Symbol

Hi can anyone help? Does anyone know what this symbol means.
Thanks in advance.

 

It's sheet arrival control on Feeder. This symbol means Feeder timing has reached to the limit.

 

Thanks for that it only seems to appear when I’m printing both sides work & turn etc…
Does the timing need adjusting?

 

Yes, I would recommend to check the timing.

 

You should be able to turn off the automatic feeder timing option and manually time the feeder to the front lays on your cptronic display.

 

do nothing, this symbol is displayed when the margin is good

 

So if this error is constantly giving issue and is permanently showing....on the non operator side there is a chain and gear inside the cover frame below the motor. Once you open the cover below you would see a chain moving on this gear which has + and - setting on that. What it looks like is that the paper in ur case is advance so turn the gear to - direction to slower the advancement of the paper. The adjustment has to be super minor. Try this I am sure the issue would be resolved...
