U1 is a right cover open error. So either that cover is not closed all the way, the tab on the door itself is not hitting the sensor that detects if it is closed, the sensor itself isn't working properly and lastly it could be board malfunctions. Most times on this model it is either a broken tab on the door or it is not shutting correctly. The front door has to be completely shut before the right door will shut. If you are looking at the right dooor straight on the sensor is at the bottom left corner of the machine. There is a little **** in the plastic that is where the sensor is. There is a piece of plastic on a spring that is on a guide that slides back when "triggered" some times that can come off the guide.
Hope this helps.

Hi.. To fix the E527 error, close the front panel (cover A) and open the top cover (cover B). With the photoconductor unit removed, the toner carousel will rotate. It only rotates if cover A is closed all the way. You can easily rotate the carousel to a position where you can remove/reinstall the toner cartridge if stuck.

Hello, this code is : Fusing temp. warming-up error. This means that the fuser did not warm-up in the allowed time. Possible causing-- in order; Thermistor bad or out of position, fuser lamp bad, thermofuse bad, BICU board defective, power supply board bad, poor fusing unit connection ----check this first if you had the fuser out of the machine.
If you would like to talk, I can see if we can try to reset the code -- sometimes if the machine is to cold at warm-up the code will throw. # 216-701-1591. Thank you.
There is a long list here for the U2 code so if you let me know I will tell you what it means..
Again what is the Last part of the Code?
If it is U2-40 code, it is a Crum Chip, Take the toner out clean the end of the toner cartridge, there is a chip, a small plastic connection piece with bronze/silver wire on it.
Or replace the toner cartridge.
You will also need to clear the code with simulation 16.
Turning the machine off might work but, not usually.
