Oki DP-5000 manual Is the ink cartridge head dirty?

2Is the ink cartridge head dirty?

Clean the cartridge head by refering to Chapter 5, Maintaining the Printer. The platen often gets dirty at the same time as the head, so it is recom- mended to also clean the platen.

3Is the platen dirty?

Clean the platen by refering to Chapter 5, Main- taining the Printer. If cleaning the head and the platen does not work, contact the supplier from where you purchased the printer.

4Are you using the correct ink cartridge for the chosen printing medium?

Use only OKI ink cartridges for the DP-5000 printer. When printing in colour on the glossy side of a greeting card, use only metallic ink car- tridges.

5Are you printing on a rough or special surface (such as overhead transparency film)?

Rough or specially treated surfaces may not allow the ink to adhere well, resulting in gaps or distor- tions. In such a case, use a halftone setting appro- priate for the image.

6Are you printing images with sudden colour variations or very bright colours?

In these situations, the overlap of different col- ours of ink can degrade the quality of the image. Reducing the amount of halftoning can reduce this effect. Use a halftone option appropriate for the image.

7Are you printing on envelopes, thermal paper, or picture cards?

Printing is unreliable on envelopes and other sur- faces which have a non-uniform thickness. Print- ing and feeding of thermal paper is unreliable. The paper side of picture cards may be printed on if the surface is smooth and the card thickness is 0.23 mm (0.01") or less, but printing on the photo side is unreliable.

8Are you printing on the wrong side of the paper?

With both VPhoto Print Film and Dye Sublima- tion Paper, printing should take place on the glossy side. Take care not to print on back of the paper, particularly with Dye Sublimation paper, while using the Dye Sub ink cartridges as the rib- bons in the cartridges may break.
