3 Is 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.
4 Are you using the correct cartridges for the chosen printing
medium?
Use only OKI cartridges for the DP-5000 printer. When printing
transparencies, use only recommended Overhead Projector
Transparency Film (A4).
5 Are you printing images with many sudden colour variations or
very bright colours?
In these situations, the overlap of different colours 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.
6 Are you printing on envelopes, thermal paper, or picture
postcards?
Printing is unreliable on envelopes and other surfaces which have a
non-uniform thickness. Printing 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.
7 Are 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.
8 Are 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. Particularly 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.
