Question mimaki cjv 30 issue

hello,cjv 30-130, should i adjust the motor , when the machine come to the cappaing station, seems it needs to travel a bit more so the head is entirely covered by the cap. A lot of times it hit the cap and not sit fully and right away throw me error code 07. I have to tilt the capping slider more to the inside the and to the left more like a touch by 1/8 " , and it work to boot up and ready, any idea, when i do test print the print carriage run so fast and with horrible force from left to right and vibrate the whole machine , scary ,. pls give some suggestion, thanks
