@Tina1969 Here's what you need to do, to resolve this issue once and for all:
have you customized the printer's ePrint email address? If you wish to keep the ePrint email address you will need to try logging into that HP Connected account using another email.
If you do not wish to keep the printer's ePrint email address or have not customized it yet. We can easily fix this by removing and enabling Web Services. This will release the printer from the old HP Connected account allowing you to add it to your new HP Connected account.
We need to remove the printer from the other HP Connected account. To do this please follow these steps:
1. Press the ePrint button (Web Services menu) on the bottom left-hand corner of the printer's front panel menu. Here, you can check to see what the ePrint email address is.
2. Go to 'Settings' or select 'Remove Web services'.
3. Once complete, enable 'Web services'.
4. The information page will print with the new claim code (everything prior to @hpeprint.com).
