2Is the ink cartridge installed in the holder with the
(A) side up?
Make sure the ink cartridges are placed in the holder with the identification markings (B side) facing up.
3Has an ink cartridge for a different printer been installed?
Ink cartridges made by other manufacturers will not work. Use only ink cartridges recommended by OKI.
Printing quality, hue, and resolution queries
1Can all four colours of the colour inks be combined for black and white printing?
If Darker Black is set in colour printing or if the brightness and contrast settings are correct,
For monochrome printing, select Greyscale under Document Type.
2Black is printed with black ink, but grey portions are printed using four colours.
In colour printing, greyscale intermediate colours (such as grey) are printed using four colours. If you want to print only in black ink, set the Docu- ment Type setting in the Document/Quality tab in the Print dialogue box to Greyscale.
3I would like to adjust the image quality of photographs without reducing character resolution.
Characters always print at the currently selected resolution (if an outline font is used). The image quality of photographs can be adjusted independ- ently using the Halftone setting in the More Set- tings dialogue box.
4There seems to be no difference between photographic output using monochrome printing at ‘Fine’ and images obtained by monochrome printing at ‘Standard’.
When monochrome printing in Fine, only the characters can be printed at 1200 dpi. This is done by smoothing the 600 dpi images. The qual- ity of photographs, however, differs little from that of images obtained by monochrome printing at Standard.
