Printing is faint.

If the printing is faint, check the following.

1. Check printing surface of TPH. (When the overall printing is faint or only one side is faint.)

1-1. Foreign substance on TPH could make the printing faint.

1-2. Check and clean the printing surface with Cleaning Pen.

1-3. If the printing quality does not change after cleaning, check the following.

2. Check the paper (When the overall printing is faint)

2-1. Printing quality very much depends on the quality of the paper.

2-2. Check the printing quality using highly sensitive paper.

3. Adjusting printing density

3-1. All types of thermal printers have functions to adjust printing density.

3-2. You can check the printing density settings by checking the settings of Dip S/W with User Manual, and adjust the density accordingly.

3-3. If you make the printing density too high, it could reduce the lifespan of TPH.

4. When one side is faint or white lines are produced

4-1. Clean the printing surface as described in step 1 shown above.

4-2. If one side is extremely faint or white lines are produced, contact the service center as the problem could be mechanical deformation or troubles in TPH or main board.
