I am trying to check the warranty status of my M425dn.
At the warranty check page, I enter my serial number and click Submit. The page returns "This product cannot be identified by serial number alone. Please enter a product number below or edit the serial number above."
I then enter the associated product number as listed on the unit's rear sticker: CF286A. I click Submit again. Now the page returns "This product number is not associated with the serial number provided. Please review your records and make any necessary edits."
I have triple checked my serial number and product number. I very much need to know the warranty status of this unit. What do I do?
