#Technology to ensure and improve print quality

Nozzle Verification Technology

Clogged nozzles of the Printhead are automatically detected when printing each sheet, and the print quality is adjusted accordingly. In addition to maintaining print quality, it also reduces waste during mass printing due to clogging nozzles. Nozzle clogging detection is performed at various timings such as before printing, during printing, and after printing.

BRS Technology (BRS: Banding Reduction System)

Excessive ejection of ink into the same pixel due to ejection characteristics of each nozzle and nozzle arrangement factors is corrected to make the image uniform on the printing surface.

Head Cleaning

A function that performs maintenance by ejecting ink to recover nozzle clogging. Three types of head cleaning (CL) are installed, and the head cleaning strength is as follows.

(Weak) CL0 < CL1 < CL3 (Strong)
When performing cleaning in the normal mode, the cleaning type is automatically selected according to nozzle clogging by the nozzle self-diagnosis system, thereby suppressing wasteful ink consumption.  The cleaning can be individually selected and executed from a service support mode built in the main unit.

CL0

For clearing the slightly clogged nozzles. Applies pressure to the upstream of the Head Unit to push out the ink through the nozzles, and removes the air bubbles accumulated around the nozzles by wiping with that state. In addition, prevents air bubbles from entering when wiping

CL1

The purpose is to recover from moderate nozzle clogging. Air bubbles inside the head and nozzles are removed by flowing ink inside the head unit. Note that CL0 is also executed at the same time.

CL2

The purpose is to recover from severe nozzle clogging. By flowing ink through the ink circulation path and inside the head unit, air bubbles inside the ink flow path, head, and nozzles are removed. Note that CL0 is also executed at the same time.

Power CL

Perform CL2 twice in a row.
