What Does 4803 Error Mean and the Reason Behind this Issue?
The Kyocera 4803 Scan Error arises when the MFP encounters a problem establishing a secure connection with the email server during the scan-to-email process. This error typically stems from compatibility issues between the MFP’s encryption protocols and the email server’s security settings.
In simpler terms, the MFP and the email server are speaking different encryption languages. The MFP might be using newer, more secure encryption protocols, while the email server might be clinging to older, less secure ones. This mismatch led to a communication breakdown, resulting in the Kyocera 4803 Scan Error.
Procedure for Solving Kyocera 4803 Issue
Now that you understand the root cause of the error, let’s embark on a journey to vanquish it. Follow these steps meticulously, and you’ll be back to sending scanned documents via email in no time.

Bonus Tips – Different Kyocera Send to Email Erro Codes and Reasons
In addition to 4803, here are some other common Kyocera scan-to-email error codes and what they mean:
4804 – Error in the recipient’s email address specified. Double-check the address entered.
4806 – The scanned file exceeded the allowable size limit for email set on the printer. Lower the scan resolution or split it into multiple emails.
4808 – Authentication failure likely due to incorrect SMTP login credentials configured. Verify the username and password.
4812 – The scanned data could not be converted to a TIFF or PDF file for email attachment. Try rescanning the document.
5000 – The printer’s memory is full preventing scan processing. Delete unused jobs or adjust scan settings.
5500 – General communication error during email transmission. Indicates a problem connecting with the SMTP server.
5501 – Email transmission timed out. Network connectivity issues are likely preventing communication.
5502 – The SMTP server actively rejected the message and did not specify a reason. Contact your email admin.
