I worked on a CM2320. One of the described problems was that it kept initializing. One of the problems I found was that the wall plug was just barely plugged in--it kept powering off and on as the machine vibrated.

Now, email addresses can't be stored in the contact list or in the history. When you look at the email history on the machine after sending an email, it shows no addresses. When you go to the tools via web browser from a PC, and look at the contact list, it shows 50 duplicate email addresses--all of them the last email address used to send from the machine. You can't add any and when you try to edit what's there, it doesn't save it.

When you type in the email address on the machine, the machine scans and sends it fine. But it won't store the email addresses anymore.

The customer claims this function worked fine before I worked on it, but it's not something I ever thought to test, so I can't say for sure.

Firmware version is 20100512.
