Why am I getting a 'USB write error' on my SATO CL4NX?
If your SATO printer shows a 'USB write error', connect the USB memory if it is disconnected. If the copy area in the USB memory is not sufficient, make sure that the USB memory has sufficient copy area. If writing to the USB memory fails, replace the USB memory. If the USB memory is not formatted, format the USB memory.
What to do if my SATO Label Maker shows a 'Media error'?
A 'Media error' on your SATO Label Maker can stem from a few causes. First, verify that the configured media size matches the size of the loaded media. If they differ, adjust the settings accordingly. Also, ensure that the print data doesn't exceed the configured media size. Finally, an incorrect sensor level can cause the media to feed improperly; adjust the sensor level to correct this.
Why does my SATO CL4NX Printer say 'head density changed'?
If your SATO Printer displays 'head density changed', it means either the print head is not installed or a new print head with a different resolution has been installed. Install the print head or use a print head with the same density as the old one.
What to do if my SATO Label Maker shows a parity error?
If your SATO Label Maker displays a parity error, it could be due to incorrect RS-232C settings. In this case, adjust the interface settings correctly. Alternatively, the cable connection may be incorrect; ensure you check and connect the cable correctly.
What to do if my SATO CL4NX shows an 'Overheat error'?
If your SATO printer is showing an 'Overheat error', the temperature of the printer has exceeded the tolerance value. Stop the operation of the printer to let the temperature decreases.
Why does my SATO CL4NX Printer display a media error?
A media error on your SATO Printer can occur if the configured media size differs from the loaded media size, the print data is too large for the configured media size, or the media is fed incorrectly due to an incorrect sensor level. Check the configured and loaded media sizes, verify the print data, and adjust the sensor level.
What causes a machine error on a SATO CL4NX Printer?
If your SATO Printer displays a machine error, it is likely due to a defective circuit board. The suggested solution is to replace the main board.
What does 'Head resolution error' mean on SATO Label Maker?
A 'Head resolution error' on your SATO Label Maker may occur if the print head is not installed; install the print head.
