How do I clear the flashing Paper and red Status LEDs (lights)? The Status Monitor states Paper Jam, Incorrect Paper Size for Auto DX, or Size Mismatch, what should I do?

Description of Solution 200000022839

If the Paper LED and red Status LED are flashing, this indicates either a paper jam, incorrect paper size for auto DX (duplex), or a paper size mismatch.


1. Verify the program being printed from (MS Word, Quickbooks, etc.) and the correct drivers are loaded on the computer.


2. Check for a paper jam in the MP tray or paper tray as follows:


a. Press the front cover release button and open the front cover.


b. Slowly take out the drum unit and toner cartridge assembly. If paper is jammed, it will be pulled out with the drum and toner unit.



NOTE: Place the drum and toner unit on a piece of disposable paper or cloth to avoid spilling and scattering the toner.


c. Remove the toner cartridge from the drum by holding down the lock lever (blue tab) on the right side of the drum unit and lift the toner out.




NOTE: Handle the toner cartridge carefully. If toner scatters on your hands or clothes, immediately wash it off with cold water.


d. Remove any jammed paper found in the drum unit.


e. Place the toner cartridge into the drum (be sure it clicks into place).




f. Reseat the drum unit into the printer pressing it in securely.




g. Close the front cover making sure it latches on both sides.


h. Open the MP tray door and remove any paper from the MP tray. Close the MP tray door.


3. Check if the paper tray is installed correctly as follows:


a. Pull the paper tray completely out of the printer.



b. Pull any jammed paper down and out of the printer.




c. Remove the paper from the tray and set the paper guides to the correct paper size.


- It will be necessary to hold the release levers (1) when moving the guides to a larger size.


- The release lever for the left and right guides is located at the middle of the right guide.


- The release lever for the rear guide is in the middle of the rear guide.


NOTE: Make sure that the rear guide does NOT push tightly against the paper. It should be set to the position marked for the paper size that will be loaded into the tray.  If the rear guide is pushed too tightly against the rear edge of the paper, the paper may be unable to feed properly.




d. Slide the paper tray back into the printer. It should slide in smoothly. If it doesn't, check for any obstructions where the tray slides into the machine such as a paper clip, pen, paper, or other item.


e. Make sure the Paper LED is off and then, the Status LED turns green.


f. If the printer does not start printing, press the GO button.


4. Check that the paper size selected in the printer driver setting matches the size of paper you have in the MP tray or paper tray. The paper sizes you can use for automatic duplex printing is A4, letter, legal, or folio. Press GO after verifying the paper size is correct.


5. If the printer still indicates the error, perform a factory reset on the printer by doing the following:


a. Turn off the printer.


b. Make sure that the front cover is closed and the power cord is plugged in.


c. Hold down GO as you turn on the power switch. Keep GO pressed down until all the LEDs light up and then Status LED turns off.


d. Release GO. Make sure that all the LEDs are off. 


e. Press GO eight times. Make sure that all the LEDs light up to indicate the print server has been reset to its factory default settings. The printer will restart.
