Hello Cathy O,
Thank you for your response and suggestion. We will therefore escalate the information to the Support Department.
Both those codes are Communication Errors and the only thing the Knowledgebase suggests is to try to power off for 2 minutes and power back on. If that doesn't work, it suggests to contact the Support Department for more assistance: 1-800-821-2797
We have the unusual problem with network controler on Altalink C 8045.
Machine does not see the network (no LED blinking) and it does not respond to ping.
Fault codes are 316-501,303-331 give nothing consistent to solve the problem.
