I have Several Printers that are showing up in the De-duplication Dashboard. They have the same Name, But Different IP addresses and Serial Numbers. I have attached my Identification Rule as well as my Related Entries. I am newer to CMDB and any help would be appreciated.

Hi @Amy Stamper,
Your printers are being flagged as duplicates because your Identification Rule likely includes Name as a unique identifier. Since "im 2500" looks like a generic model name rather than a unique hostname, the system sees multiple devices with the exact same name and flags them as duplicates, even though their IPs and Serials differ.
You can fix it as below:
Open CI Class Manager and navigate to the Printer class (or the Hardware class if the rule is inherited).
Check the Identification Rules. You likely have an entry that attempts to identify based on Name alone.
Remove or lower the priority of the "Name" rule. You should rely primarily on Serial Number or Mac Address for printers, as names are often not unique.
Clean Up: Once the rule is updated to rely on Serial Number, you may need to manually process the existing de-duplication tasks (or delete the incorrect CIs and let Discovery recreate them correctly).
Best Practice: Ideally, all CIs on your network should have unique hostnames, but if that isn't possible, your CMDB rules must be adjusted to ignore Name for identification.
If you find my response helpful, mark it as helpful and accepted solution.

Maham Tahir.
