7-2-1. Procedure for Solving the Print Quality Problems

Follow the procedure (Step 1 to 7) below until the print quality problem is solved.

<Note>

The following steps are shown with CMYK Print Heads and do the same in case of White Print Heads.

Step 1: Clean the Print Heads by pressing the Head Cleaning Button.

Head Cleaning with flushing fresh ink can solve most print quality problems. See “7-2-2. Cleaning the Print Heads / Using the Head Cleaning Button” and do it a maximum of five times. Check the nozzles by test printing of Nozzle Check Pattern (see "7-2-3. Checking Print Quality with Nozzle Check Pattern "). If the problem is not solved, go on to the next step.
