Hello dddhunhan,
Please take a look at this article for assistance with code 93, 983. If you are still having issues after trying these steps, I suggest that you call into our support department for assistance @ 1-800-835-6100.
I replaced the process gear because error code 94,700 appeared on the printer.
After that, the error code 93,984.00 suddenly appears in the cleaning state before the printer is ready for power. What is this? What can I do?
