Troubleshooting 3 of 6
Machine Problems
If the device rejects the file or changes output unexpectedly, confirm the supported encoding and color mode in the exact software and machine documentation, then test a known-good file.
Separate file acceptance from output defects. If the machine rejects a JPEG, verify supported coding modes, color modes, size limits, and software version. If it accepts the file but the output fails, compare machine state, maintenance, preset, and material using a known-good test.
Use a known-good file to distinguish a current machine issue from a JPEG-specific one. If both the known-good file and new image fail, check machine status, media, consumables, and maintenance. If only the new image fails, compare encoding, color mode, size, and import settings. Follow the exact manufacturer's troubleshooting and safety guidance; do not prescribe generic heat, power, or speed adjustments from the image format.
