4. Humidity Control

Ideal humidity for printing is between 45 and 55 percent, at a temperature of 68-72 degree F. (20-22.2 degrees C.)

Low Humidity problems:

1)Media warping and edge curl problems leads to visible carriage head strike on media surface.

2)Inconsistent print quality is normally observed in severe low humidity environments. To compensate more ink must be used to balance the color loss (need for color profiling).

High humidity problems:

1)Dry time drastically increases with high humidity levels.

2)Lamination issues often result; increasing time required to finish jobs. Refer to Installation Step #15 above for lamination guidelines.

These problems can be avoided by maintaining proper temperature and humidity levels (RH) in both storage and operational areas. The use of humidifiers will add water to the air, resulting in a humidity level increase. This will help prevent normal heating season problems caused by dry air.

General Environmental Conditions

Controlling the print location and surrounding humidity is key toward maintaining good color output no matter what environment or region the printer is located in.

5. Edge Band mode

To eliminate instances of ‘First Drop’ (color change at print edges) from occurring ensure the Edge Band mode is turned on. Select Setup Menu – Paper Option Menu – Margins. By selecting Edge Band the printer will be forced into Normal Margins and a vertical bar of 6 colors will be printed along both media edges. This will force the cartridges to warm up by

printing data outside the page layout, thus decreasing the chances of ‘First Drop’ from appearing along printed edges.
