Optimizing the Parameters of a Maintenance Station

Tally has developed a new high-power inkjet printer. Two significant aims of the development were low costs per page and high-speed printout. During this project a maintenance station was designed and optimized with regard to the a. m. points. The maintenance station works with underpressure and is able to clean the nozzle plate of the piezo-printheads with a wiper, which removes the oil based ink and paper dust. A separate cover protects the maintenance station from paper debris during printing.In order to save time and ink we examined the influence of various parameters as the amount of underpressure and the effect of sudden pressure changes on the maintenance efficiency and functional stability of the printheads. The analysis revealed reliable and less reliable areas.Furthermore, we tried to find out how the ink consumption could be minimized during the cleaning process. In all measurements the nozzle failure was not provoked, but occurred when printing a normal print job. As a result of our investigations we could define a working area for the printer maintenance with a high nozzle recovery efficiency an a low ink consumption.
