The touch screen could have lost its calibration, but there is a good chance that it is bad, and needs to be replaced. To calibrate it, push the yellow clear modes key, then the numbers 1, 9, 9, 3, then push the red "Clear / Stop" key 5 times, and choose number one. Follow the prompts. Use a stylus or other dull pointed item. If you don't get a response, you need a new touch screen.

Most fuser problems have to do with the fuser lamp and or the thermistor, or the thermal fuse. If you can put you hand near, and I did say near, because the fuser is very hot and can burn you, you should feel heat. Use an inferred thermometer to pick up heat. Should be around 225 degrees F +- a few degrees. If no heat detected the lamp is bad or is not receiving voltage. The thermistor detects heat from the fuser roller, it lays on it, and sends a signal to the logic to turn up the voltage to the lamp or turn it down. The thermal fuse could be open hence not voltage to the lamp. Last but not least no power from power supply or no signal from logic board to turn up the juice. Hope that helps.

you need to replace dram blade developer

Transfer roller is grounding out cause could be developer powder spilling over time and has now created a path to ground causing it to leak voltage

kindly check the cover that the machine is showing and close properly

i think you need to replace your developer unit a new one!

Hard Disk Drive - identical to the one in your computer (but probably a different size). It is where the images are stored when making copies. If you have a failure, then it is probably reporting that it cannot read or write to the hard disk.

LD unit beam pitch adjustment incorrectly.

It could be that the shifting roller that shifts paper from side to side in the almost top area of your finisher has its movement blocked, or that there is a defect in its motor. This roller lies below the flat black paper guide that leads paper out onto the finisher's shift tray.
