DELL c1765nfw, stopped printing in color - error 007-371, code:1000000
I have a printer (DELL c1765nfw) that I bought last year in May (warranty lasts until May 2017). It was working fine until couple months ago. Upon requesting to print it loaded up and prepared like normally, but just before printing it became silent (sounded like it suddenly shut off) and error message appeared on it's panel screen with error 007-371, Code:1000000 . The same happened after I restarted it and tried again. I also tried printing from USB and copying - same error. One of the toners was changed not too long ago, but it still printed just fine after the change.
I looked for any jammed papers or other small items in it from the front, and after opening rear panel, from the back, but there didn't seem to be anything. I also removed and checked all toner cartridges. The problem still appeared, and I was getting the same error. I tried printing in black and white and it worked, but after requesting to print in color I got the same error message. I even changed all the toners to new ones (even though some of them still had more than 50% of powder left) - it still didn't print in color.
I would want to know what does this error mean (printer's manual for this error just states to contact support), and what should I do. I sent an email to dell support but got no answer. I looked in dell's and other forums, but couldn't find a clear answer, just a suggestions that the printer's head device might be faulty.
Thank you in advance for any help you can provide.
