Specifications-RelatedRegarding the replacing operation of photo-interrupter (shift tray- D1/E1/F1)[Detail]In the machines prior to the Countermeasure cut-in serial number in factory described below the photo-interrupter used for thesift tray assembly of shift trayD1/ E1/ F1 each (total number of the photo-interrupters is 3) is changed for supply reason.- Old type : Photo-interrupter (FK2-0149-000)- New type : Photo-interrupter (WG8-5783-000)When the photo-interrupter or a related part is replaced in accordance with this change, please follow [Servicing Work] set forthbelow.[Service work]a) For shift tray -D1a-1) When the photo-interrupter [1] or [4] for old type shift tray -D1 is replaced individually, use old type photo-interrupter(FK2-0149-000).a-2) When the photo-interrupter [1] or [4] for new type shift tray -D1 is replaced individually, use new type photo-interrupter(WG8-5783-000).a-3) When the replacement of photo-interrupter [1] on the tray assembly [2] is needed, the replacement of tray assembly [2](FM2-4454-000) is also available instead of the replacement of photo-interrupter [1].a-4) The sensor cover [3] goes out of use. When the replacement of sensor cover [3] is required due to its damage or anotherreason, prepare and replace the tray assembly [2] (FM2-4454-000).b) For shift tray -E1b-1) When the photo-interrupter [1] or [4] for old type shift tray -E1 is replaced individually, use old type photo-interrupter(FK2-0149-000).b-2) When the photo-interrupter [1] or [4] for new type shift tray -E1 is replaced individually, use new type photo-interrupter(WG8-5783-000).b-3) When the replacement of photo-interrupter [1] on the tray assembly [2] is needed, the replacement of tray assembly [2](FM4-5078-000) is also available instead of the replacement of photo-interrupter [1].b-4) The sensor cover [3] goes out of use. When the replacement of sensor cover [3] is required due to its damage or anotherreason, prepare and replace the tray assembly [2] (FM4-5078-000).c) For shift tray -F1c-1) All shift tray-F1 are manufactured with new type photo-interrupter (WG8-5783-000) [1] and [4]. When the photo-interrupter[1] or [4] is replaced individually, make sure to use new type photo-interrupter (WG8-5783-000).c-2) The sensor cover [3] goes out of use. When the replacement of sensor cover [3] is required due to its damage or anotherreason, prepare the tray assembly [2] (FM1-J711-000) which has been set up as a new service part and then replace the originaltray assembly with the new type tray assembly.88
