There is a chip on each cartridge that the printer reads when it is inserted. Sometimes the glue that holds the chip in place comes loose and the chip falls off. Seen this happen, especially with refurbished cartridges. Or maybe the chip is bad itself. Try to use your old cartridge and if you don't get this error, then you know it is the chip and or the cartridge.

If your printer has a maintenance cycle try running it. The drum might be dirty.

check the type of paper is correct, if it is you can clean the rollers, etc use alcohol / distilled water mixed 50/50

If you print a test page from the printers control panel, does it print in color? (Like the supplies page)

Please change the LSU because the LSU unit is damage

There is a solenoid on the transfix assembly that has a tendency to "stick" in the open position, causing paper jams at the exit. The Solenoid is located on the right side of the machine, at the top area in the middle. You can test it with your fingers to see if it sticks in the up position. If it is, simply clean the sticky residue off both metal surfaces with alcohol and it should return to normal operations.

You may have the "separator page" option turned on in your print driver. This option will insert a blank page after each print job to separate one print job from another. Simply uncheck the box by the separator page option and you should be back to normal !

This type of print quality defect shows up if you have loaded the wrong type of paper in your machine and didn't remember to change the paper type (plain paper, card stock, labels, etc.). This can also happen if the paper has a high moisture content, or if the humidity in the room is too much. Also make sure the room temperature is within its normal operating range (not too hot, not too cold). The problem you describe could also be caused by using non-Xerox toner/drum units. Compatible toners don't work very well in Xerox printers. Aside from those problems, the only other thing would be if the Fuser Assembly is near the end of its life...it will also cause some print quality problems like you are describing.

This indicates a process drive or printhead error has occurred. The printhead is stuck or is not tilting properly. Check that the process drive gear train is properly homed. Check for obstructions or ink spills around the printhead. (was the printer tipped on its side or moved while the ink was still hot?) Check for blockage in the purge tube. Verify the printhead travels smoothly from left to right. Check to see if the process drive gears assembly is loose (broken frame where screws are).

The printhead temperature is too low. Check the air temperature (the room should not be cold) Test the heaters in Service Diagnostics Monitor. If the heaters function properly, then replace the Electronics Module...if they don't, then it could be a bad printhead, drum assembly, drum heater relay board, or drum temperature sensor.
