Make sure that the ribbon will be threaded under the guiding pins of the
print head (see illustration below).
Caution! The print head may be hot!
Tighten the ribbon again by turning the knob several times.
First close the document plate and then the printing mechanism. Finally
close the housing cover.
Notes on the automatic document detection
In order to guarantee a good readability for the automatic document detec-
tion the indicated lifetime of the colour ribbons is at a limit of 23% for the
contrast.
You will find the exact limit for the automatic document detection in the
description of your scanner. Depending on the type of device a consider-
able lower lifetime of the colour ribbon might occur.
With regard to the document detection you may increase the lifetime of the
colour ribbon by printing the text on a bright background, by selecting the
double print option and by using violet colour ribbons instead of black
ones.
