I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).

If you are unfamiliar with how the Community's private message capability works, you can learn about that here.

I got the message from them to inform me that the warranty on my printer has expired.

So it seems like the power supply does in fact resolve this issue, the high voltage supply to be specific. Thankfully there are still some printer repair technicians in this world. Here is the link to the part: https://www.laserxperts.com/rg5-7985.html, it costs about $30 but maybe you can find cheaper on eBay? At any rate, for those interested here is a copy of the schematic that details the power supply/toner cartridge circuit diagram. It's really too bad we have to do this research on our own, this should be something HP should've provided especially since a previous user already mentioned this was the solution.
