blinking yellow triangular light when trying to print on LaserJet P2015dn

[Scribblegirl]

The yellow light is blinking next to the traingular icon with the exclamation point. The toner cartridge is new, there's no paper jam, and there's plenty of paper. Restarting the machine doesn't help. And there's nothing in HP's support solutions that covers this.

Here are the reported error messages from today, beginning with the most recent.

E [02/Nov/2017:14:05:30 -0400] Unable to register ICC color profiles for "HP_LaserJet_P2015_Series": 1001

Help please!

According to the Laserjet P2015 User Guide manual, your reported light pattern indicates that the toner (print cartridge) door is open:

 

I've no idea about your error messages (I don't use Mac systems).

Except it isn't open! Never had this problem before & am totally at a loss. Thanks for your response, though.

The symptoms seem to suggest that the printer thinks the door is open.

Perhaps when you changed the toner ("... toner cartridge is new ...") you managed to dislodge some sort of sensor?

I can't advise with more details of this, sorry  (my expertise is with printer language, not hardware).

I think you may be right but I have no idea how to fix it! Thanks for your insight.

Perhaps just try to remove and reinstall the toner cartridge - you may not have pushed it fully home when you installed it before?
