I dont have screenshots, but see if you can navigate thru the below steps to setup gmail on you xerox device.
Gmail Setup is as follows.
1. Server = smtp.gmail.com
2. Port = 587
3. Make sure encryption is turned on
4. Use STARTTLS (encryption)
5. Use SMTP AUTH (login credentials)
6. Use System (login credentials)
7. Login Username would be full Gmail email address.
8. There may be up to 4 places to enter the Gmail email address (on different screens). They all must match.
9. Login password would be your Gmail account password.
10. Disable certificate checking.
11. You will need to manually log into the Gmail account using a browser and allow "less secure apps". (Google this for details).
12. Ensure that your subnet mask, gateway, DNS settings are correct on the xerox device. They need to match the settings of your network.
13. You may also want to add .local to the hostname and domain name in DNS settings on the printer.
Let us know what the results of this are
First, keep in mind that it's extremely rare (nearly never) for this type of issue to be caused by a fault of the device itself (especially when email is the only thing that is affected).Your settings may not have changed but the most common reason for this issue would be that something outside of your xerox device has changed. The trick is to find out what.
Here are some general possiblities...
1. The most common would be a changed password for the email account that the machine is using to log into the remote smtp server. If this was changed (and authentication is enabled) then the machine is still trying to use the old password to log in, which no longer works.
2. The remote smtp server has changed something like which port to use, adding encryption or authentication requirements, etc. When this happens they do not notify anyone beforehand. Email just stops working.
3. The machine current software no longer supports the latest security emplemented on the smtp server (when the smtp server changes are made). You mentioned that you already updated the firmware.
4. Something on your network has changed - IP scheme, default gateway, DNS, changes made by network admins, etc.
5. Someone changed a setting within the machine that is not obvious.
Answers to these common questions will provide clues as to which troubleshooting path will most likely lead to the solution. By answering these questions, you are helping us to help you. Please reply with answers to these questions whether you feel they are relevant or not...
1. Can you print to the machine?
2. Do all other functions on the device work correctly (besides email)
3. Was there a know change made to your network? (could also be an unknown change if this is not a simple residential network).
4. Did you change ISP service or did your ISP make any changes to your network or service?
5. Did you change email service?
6. Who are you using for smtp (sending email) service?
7. What is the smtp server hostname that you are using? (ex. smtp.gmail.com)
8. Were any changes made to the machine settings that you know of prior to email failing?
9. Were there any recent power issues that may have affected power to the machine (this can sometimes corrupt settings in the machine, but it's rare)?
10. What is the current version of firmware on the device?
11. How familiar are you with networking and smtp settings?
Once you provide the answers to the questions above, we can assist with pointing you in the right direction to narrow the cause.
