Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble, Jenny.
This code is an indicator of a "density sensor malfunction", meaning a bad sensor or a bad logic board.
What we can try here are some cleaning and reset steps.First, open up the printer, and check for any internal debris such as scraps of paper, paperclip or staple, etc. Next proceed with cleaning by blowing out the Inside compartment with compressed air and checking carefully on both sides for any obstructions. Next remove all of the toner cartridges/drum assembly, then clean the metal electrical contacts on the back, as well as where they mate up inside the printer, using qtips and rubbing alcohol. Dry well, then reseat the cartridges.
Then reset the machine:unplug power at the wall outletwait 5 minutespress and hold the power/on button for 60+ secondskeep holding while plugging back in, and for another 60 seconds after, then release
I am an independent technician and I've spent my personal time, unpaid, in an effort to assist with the question for which you solicited my services. This site works on the honor system, and to that end, I have prioritized working with you ahead of other paying customers.
Although you’ve already paid your fee to the site, I am only compensated for my efforts when customers such as yourself leave positive feedback for my work. Again I apologize there is not a better outcome here, though this is really beyond either of our control. I do hope you’ll consider leaving a 5 star rating for me, rather than “shoot the messenger”, so that I may get credit for my time spent in good faith to answer your question accurately.
