Appendix
Is there an obstruction in front of the paper output slot?
If the paper output slot is obstructed, paper ejected from the printer can fold
and bend and cause trouble. When printing, make sure that the paper
output slot is unobstructed and that there is room for paper to be ejected.
Ink cartridges are not correctly recognized
Is the bar code on the ink cartridge dirty?
Clean the bar code.
Is the ink cartridge installed in the holder with the (A) side up?
Make sure the ink cartridges are placed in the holder with the ALPS logo (B
side) facing up.
Has an ink cartridge for a different printer been installed?
Ink cartridges made by other manufacturers will not work. Use only ALPS
Micro Dry
TM ink cartridges.
Printing Quality, Hue, and Resolution
Can all four colors of the color inks be combined for black and white print-
ing?
If Multi-Pass Black is set in color printing or if the brightness and contrast
settings are right, 4-color black is possible. To print only with black, turn off
Multi-Pass Black, and return the Image setting under Image Settings to
default.
For monochrome printing, select Monochrome Picture under Document
Type.
Black is printed with the black ink, but gray portions are printed using
four colors.
In color printing, grayscale intermediate colors (such as gray) are printed
using four colors. If you want to print only in black ink, set the Document
Type setting in the Paper tab in the Print dialog box to Monochrome Picture.
I 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
independently using the Halftone setting in the Quality tab.
There seems to be no difference between photographic output using mono-
chrome printing at 1,200 dpi and images obtained by monochrome print-
ing at 600 dpi.
In monochrome printing at 1,200 dpi, only the characters can be printed at
1,200 dpi. This is done by smoothing the 600 dpi images. The quality of
photographs, however, differs little from that of images obtained by mono-
chrome printing at 600 dpi.
