Roland SC – 545EX hangs-up

Roland SC-545EX hangs-up
My Roland SC-545EX hangs-up when I am printing a 3 X 5 Square Feet tarpaulin. I am almost finish printing, about 1-inch where left before the printing is completed.
On the VERSAWORKS, the printing is completed while on the printer’s panel, it was still printing but the head doesn’t moving or printing.
I can still press buttons on the printer panel but the printing stops.
No error prompts, printing in progress indicator on the panel, print head is not moving.
