Tajima TFHX-C 18 head toubleshooting ...

Hey guys I'm working with a Tajima TEHX-C and alot of the work it has been putting out isnt very crisp. There are times when colors have small gaps in between them, stitching looks rough compared to the digitized image, small letters are barely readable and just art in general is comming out fairly sloppy. :confused:

I'm very new to this machine and I almost feel like this has to do with how fast the machine is working. I'm using the Tajima software so i doubt it has to do with that.... can someone give me a hand?
Thanks
