Scanning mode is a very frequently used operating mode in inkjet printing systems.

The advantages of the scanning process are the comparatively low costs and the possibility of adapting the operating mode within wide limits to the respective requirements and also the condition of the print heads.

In scanning mode, the area to be imaged is usually passed over several times by the print head(s). This process is called multipassing.

The print data is transferred to the half-split main memory of a print module before the start of each print movement.

During the print movement, the data is read from the main memory by a process completely solved in hardware and transmitted to the connected print head in the form of electrical signals.

At the same time, the associated print server creates print data for the next print movement and transfers this in turn to the module’s main memory.

We show some possible arrangements of nozzle rows for use in scanning operation here.
