"No Process Unit" Error

You must install a new toner bottle into the process unit before powering the printer on with the new  process unit . When the process unit initialises it checks to ensure that there is toner present. If there is none it reports no process unit. If you are replacing the process unit using the toner bottle from the one on the previous unit it will not work as it now contains no toner.  It was immediately dropped into the process unit when it was originally locked into place. 
 

When you put additional paper options on the printer you must enable the options in the Printer’s Driver Properties so you can select them from the application.  To make sure this has been done if you look at the Printer Driver Properties through your application (File, Print, T9112/6 Properties) the picture of the printer that is displayed represents the paper sources that are currently available.  If your chosen paper source is not displayed you have not selected it in the Printer Driver.  If you go to Printer Properties in the driver  (Start, Settings, Printers, Properties) and select the Printer Options heading you can now select your additional trays.  Incidentally when you do have your option enabled you can actually click the mouse pointer on the displayed printer properties in your application for the paper source you want to select and the driver will select the correct paper tray.
 

The "Replace Parts" message appears on the display when the Process Unit has reached its End of Life. Remove the End Of Lifed unit and install a new process unit and toner.

Follow these steps to clear the "Replace Parts" message:-

1. Press the Ready button to take the printer Off-Line
2. Press the Menu button to enter the Setup Menu
3. Press the Menu button repeatedly until "Clear Warning" is displayed.
4. Press the Enter button to select "Clear Warning"
5. Press the Enter button again if the display shows "Print Unit".
6. "Selected" should be briefly displayed on the printer.
7. Press Ready button again to exit the Menu and put printer On-Line.

On a long print run the printer may stop with the STACKER FULL message in the display.

Do not panic! It just means that your paper output stack i.e. you pile of paper on the lid of the printer is too large and you need to remove some or all of it. There is a small black plastic switch on the lid of the printer, if this is pushed up because of the size of your printed paper pile, the printer indicates the above error.
