when colour printing is not required it is recommended to use a black ribbon in order to increase the lifetime of the colour ribbon. the colour option does not have to be removed when printing with a black ribbon.
to install the colour option
1 switch the printer on
2 lift the top cover (2) as shown in the illustration.
3 remove the black ink ribbon cassette (11).
4 switch the printer off.
caution:the print head may be very hot immediately after printing.
the mounting of the colour option is best done from the rear of the printer.
1 insert the blue plug (40) into the connector socket (41) of the colour option.
2 move the print head to a centre position.
3 remove the connection plug (40) out of the plastic shaft (39) which is holding down the string of cables leading to the print head.
4 hold the colour option as illustrated below:
5 mount the colour option on to the print head carriage in such a way that the pointed edge (44) fits into the slot (45) and the hole (42) fits onto the pin (43). press it firmly in position until the spring clip (46) engages.
6 tuck the cable (47) behind the plastic clip (48) and under the plastic fixture (65) to avoid the cable coming in contact with the moving horizontal belt (49) or the mounted ink ribbon cassette.
