A new model “Skylark 2 (A270/A271)” will be launched in January 98. Skylark 2 is a
slightly modified version of the already existing model “Skylark (Ricoh FT2012/2212,
Gestetner 2812/2812z, Nashuatec 3612s/3612, Rex-Rotary 8612/8612z, Infotec
5121/5121 z)”.
There will be seven destination codes depending on the are a: -57 is Middle East / South
America (Ricoh), -27 is Europe (Ricoh), -29 is Asia and Africa (Ricoh), -23 is Russia
(Ricoh), -10 is Middle East/South America (Gestetner and Nashuatec), -22 is Europe and
Asia (Gestetner, Nashuatec and Rex-Rotary), -26 is Europe (Infotec).
This RTB clarifies the differences between the base copier and Skylark 2 (based on the
style of the service manual).
