Troubleshooting

Jagged edges are visible in an image.

Cause 1

Combination with halftone patterns may cause the problem.

 

 

Remedy

Set [Halftones] in the printer driver to [Error Diffusion] for the kind of data in

 

which jagged edges are visible and perform printing again. (See the Help

 

function on the printer driver.)

NOTE

•You can also perform the same procedure from 'Halftones' in the touch panel display. (See "Halftones," on p. 3-46,p. 3-59,p. 3-75,p. 3-81,p. 3-96.)

•Although data looks like characters or diagrams, it may be processed as a different type of data depending on how the application processes it.

Cause 2 Jaggies in characters and diagrams may occur when 'Advanced Smoothing' in the printer driver is set to [Off].

Remedy For characters, set Advanced Smoothing to "Smooth 1" or "Smooth 2" and perform printing again.

NOTE

You can also perform the same procedure from 'Advanced Smoothing' in the touch panel display. Further, only with the touch panel display, you can apply Advanced Smoothing settings for diagrams as well. (See "Advanced Smoothing," on p. 3-51,p. 3-64,p. 3-76,p. 3-97.)

The density is thin when printing on OHP film.

Cause

In order to improve the image quality (transmissivity) when projected with an

 

OHP device, printing was performed with the density lowered for Transmissive

 

or Reflective type in the default settings.

Remedy 1 Adjust the toner density in the touch panel display. (See "Density," on p. 3-17.)

Remedy 2 Perform an Automatic Gradation Adjustment. (See Chapter 4, "Customizing Settings," in the Reference Guide.)
