Oki DP-5000 manual Are you printing on the wrong side of the paper?

3Is the platen dirty or is there an obstruction on the platen?

Clean the platen by following the directions in Chapter 5. If anything is stuck to the platen, remove it, being careful not to damage the platen.

If cleaning the head and the platen does not work, contact the supplier from where you purchased the printer.

4Are you using the correct cartridges for the chosen printing medium?

Use only OKI cartridges for the DP-5000 printer. When printing transparencies, use only recom- mended Overhead Projector Transparency Film (A4).

5Are you printing images with many 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. Try changing the Halftone option in the Image Settings dialogue box from Fine to Standard. Use a Blends option appropriate for the image.

6Are you printing on envelopes, thermal paper, or picture postcards?

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 back side of picture postcards 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.

7Are you printing in colour on the glossy side of a greeting card?

The glossy side of a greeting card can only be printed on using metallic cartridges.

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

With both VPhoto Print Film and Dye Sub Paper, printing should take place on the glossy side. Par- ticularly with Dye Sub Paper, take care not to print on back of the sheet while using Dye Sub ink cartridges. The ribbons in the cartridges may break.
