Print-Quality Defects Troubleshooting

STARWHEEL MARKS

On some drawings (for example, CAD drawings having a thick-lined frame around them) on some types of media, you may notice some small marks made by the starwheels. These cannot be avoided.

UNEVEN FILL DENSITY

Symptoms

Blotchy area fills.

Product Fault

DAn incorrect media-type setting has been selected on the front panel and does not correspond to the media being used.

Media Fault

The ink is incompatible with the media and does not spread uniformly through the area fill.

Solutions

One or both of the following actions may be appropriate to solve an uneven-fill-density problem:

DChange the media-type setting on the front panel.

DUse a more suitable media type.

DReplace the faulty cartridge(s).

DIf the problem is occurring in black area fills on color plots printed in Normal print-quality mode, then use Best print-quality mode instead.

SPRAY

Symptoms

Smaller dots of sprayed ink located around the point at which the required dot is placed.

Product Fault

The cartridges are positioned too far from the media.

Solution

Check the carriage-to-media distance. (Details ' chapter 5.) Replace the faulty cartridge(s).
