| Machine story: | 2013-04-24 The machine was calculating on arrival. The ink ribbon is dry-out but the numbers shown in the windows and printing extensions seems to be correct. The machine internally cleaned an new oiled on the needed locations. 2013-04-25 Ink ribbon was OK on the rest of the roll. The machine tested. The calculation works well. The paper transport was not done properly. It showed eccentric small rubber wheels, who pushes the paper against the transport wheel. (they are pressed against the bigger transport wheel, and flatten on one location during the long stay.) Demounted the printing unit and especially the two axis with the effected rubber wheels. Rounded the wheels and assembled the whole together again. This solved the paper transport. The whole machine is calculating and printing properly again. |
