vz3000

Sharp VZ3000 Hi everyone - i am new here Any ideas or pictures be appreciated what part is missing here This tab should press the microswitch so that the microcontroller receives the information that the carriage is in its end position – meaning it is parked. Thanks Rafał

Ok, so actually it's a vz3000, but thought this was the best area to ask, seen quite a few in pics so know you guys have them too. Basic history, had this since new, had belts replaced in past, several years ago, about 18 months ago started to play fast and then slow, so bought new belt kits...
