I have my printer in a warehouse where the humidity is only about 10%. I'll print a shirt and it will be fine and the second shirt will have virtually no white link so after reading through the manual I suspected humidity was my issue. So after talking to a brother technician I put a humidifier under the machine and covered the sides with plastic to keep the humidity in but even with this I was only able to hit 30% humidity and nothing changed. I asking if this is actually a humidity issue or if something else is the issue. One last thing after a white head cleaning my white test prints come out at about 95%. Any suggestions would be appreciated.
