Sinajet+plotter+driver Info

| Issue | Likely Cause | Fix | |-------|--------------|-----| | Plotter moves but cuts air (no media contact) | Blade depth set in driver overrides manual setting—or tool selection is wrong (pen vs. blade). | In driver, set “Tool” to “Cut” (not “Draw”). Reset blade depth manually. | | Cuts are distorted/offset on long runs | Driver is using HP-GL when plotter expects DMPL, or vice versa. | Switch command language in the driver’s advanced settings. | | “Device not found” error | USB power management or wrong COM port. | In Windows Device Manager, disable “USB Selective Suspend.” Manually reassign COM port to 1-4. | | Registration marks fail (Contour cutting) | Driver’s “mark sensor” mode is off or mark sizes don’t match software. | Enable “ARMS” (Automatic Registration Mark Sensor) in the driver’s post-print section. Match mark size (e.g., 10mm square). |
