Why doe message say "warming up"? - HP PSC 950 All-In-One InkJet Printer

Power up your all-in-one and then after a few seconds of warm up scan

I can't be sure, but it may mean "warming up now, please wait".

The Dr lo is for the warming draw. I assume you have a warming drawer. Page 17 of your manual describes how this function works. It also states on page 11 "The Off/Cancel pad stops any function except the WARMING DRAWER, Timer and Control Lock. If you have actually unplugged the stove and plugged it back in it should come on with a PF for power failure. You push the Off/Cancel pad to clear the PF and then you have to push start to do anything else. such as bake, etc. Have you pushed Drawer OFF? That should clear the dr lo message. If this message comes on as soon as you plug the stove in or just after you push the Off/Cancell pad or after you push start or bake try to push Drawer Off. If this does not work then it apppears you have a malfunctioning control panel.

Sorry I'm late with a reply. Removed software and reloaded. Everything OK now. Thank you

Have the same problem. Suspect a lamp problem but cannot find any info/help to check lamp or to replace it

problem not clear please explain...

My book doesn't have an error message E-07, only E-01 and E-02. Both error messages will beep.
E-01 means baking area too hot. To reset open lid and remove bread case to cool. After panel message disappears replace bread case and press start.
E-02 means baking area too cold. Unplug unit and allow it and the baking area to warm. Then try again.

Hope this helps.

I had the same problem and found that one of the toner cartridges must have not been seated properly. I removed the black toner cartridge and re-fitted it. The printer now works fine again with no errors. 17H is a code relating to a fault in the rotation ......... possibly one or more toner cartridges need checking. Use the menu on the printer to turn it to the appropriate position (i.e. engine menu then select replacement of whichever toner you are checking).
Hope this fixes your as well.
