So I concluded my side of doubt to the customer and customer gave me signal to go ahead with the idea till the time we order the new part. I have doubt about strength of glue because this strip is getting lock on the end with metal part which has spring like effect for holding this strip straight with appropriate tension on strip so applying glue to this strip is doubtful for me. Now I decided to try to repair the plastic Strip by applying fast stick glue. Furthermore my customer was in hurry to get it repair. So now what is solution for this worn out Strip? I didn’t find the part in my nearby location and buying it online is not worth because of delivery time and cost. So this is main culprit because on initialize of cartridge location cradle sensor is not passing signal to logic board about location of cradle hence for detecting the location cradle bangs left and right corner on the rail. On removing the encoder strip I found that right side locking notch of the strip already worn out. So I have removed the plastic strip that is Encoder Strip which decides where to stop the Cartridge while printing by sensing the location with help of sensor which is located behind cradle of the Cartridge. On visualize inside with a torch light I found one plastic strip was hanging in between the path way of cradle. Once powered ON I found Cartridge cradle was banging left and right side end of the mechanism.
