Troubleshooting > Troubleshooting When Printing Image 2 Check if there is uneven density in the main scanning direction of the chart. Based on the seventh density (M7, K7, etc.), visually check the density to be uniform, and determine the adjustment value. In the magenta example below, M3 and M5 have low densities, you need to increase the drive voltage. On the other hand, M8 is high in density, you need to lower the drive voltage. 3 Change the drive voltage coefficient for numbers with contrast differences > [Start] key. Increasing the coefficient with [+] will increase the drive voltage and density. Decreasing the coefficient with [-] will decrease the drive voltage and density. NOTE Check the head temperature when adjusting the voltage of print head, because the viscosity of the ink changes with the head temperature and the print density also changes with the increase of the discharge amount. 4 Repeat steps until uneven density is resolved. 5 In case that no improvement is observed, contact our service representative.

Check media setting

In case that no improvement is observed, then go to next step.

Execute print head cleaning
Landing point is shifted because of high viscosity.

Load SRA3/Ledger size paper.
NOTE
Check the head temperature when adjusting the voltage of print head, because the
viscosity of the ink changes with the head temperature and the print density also changes
with the increase of the discharge amount.
