QuickMaster Classic - Speed error

I tried to imaging new job, but the press gave me error message - SPEED ERROR! Why happened this error? I used SF 56 3+7 and 93 function to autocorrect speed of press. Now it is working, but why happened this error?

 

Probably, you didn't pay your electricity invoice Marko.

Ha ha... Funny answer, my dear Rozek. I tried to your suggestion, but nothing happened! I regret to inform you that your idea didn’t work AGAIN!

 

Don't be so curious, but glad it's working again. Maybe next time it will not. Than look for your all, old not paid invoices.
You will for sure find one for the consumable from me.
