Ran into the same problem with this DVD player and my LG tv. Try this:
Open the DVD tray, with the DVD tray open press the HDMI select button until the proper resolution for your tv is illuminated, put the DVD back in, close the tray and try again. Simple fix -- worked beautifully for me.

Good luck

SOURCE: Invalid Imaging Unit and Toners

Sorry about my last post. I didn't realize that it would be placed unter solutions. BUT I did get a resolution from Samsung. They passed me to the advanced team and they suggested I use a special code they gave me to reset all the machine. As I said before the machine was giving me an error that all the toners and the imaging unit were invalid. Samsung said to try this and if it didn't work they would send me a new (refurb) unit. They said to press in sequence <menu><#><1><9><3><start (b&w)> then when the unit cycles it will ask to imput the country, in my case I entered the US. The machine will then reset itself and all the cartridges and imaging unit should be reset to work. IT WORKED!! The machine said to wait while it re-installs the toners. When it did the red warning light turned off and the printer is working great. Hope this helps.

on a calc that's work properly, in the 'y=' screen, none of the 'Plot#' things are highlighted. try pressing 'y=', and if you have a 'Plot#" in a black box, go up to it and press enter to un-highlight it.
either it will work as soon as you press 'graph',or you have another problem

The picture I took look grainy. Just started doing this.. do you have any suggestions Thanks susie


If the pricture was taken in low-light then it just will look grainy. If not then make sure you're zoomed all the way out (i.e. not using Digital zoom as opposed to Optical Zoom) and make sure the resolution settings on the camera Menu are set to the highest setting.

Can i set the printer to print black only


Hi ethelinebake.

I thing the right way to ask would be..Can i print without colour, and the answer is, yes in Greyscale
I am from Denmark, mayby some of text and pictures not look simular to yours, but i think you can see what i mean - ok
Go to controlpanel ->Printers (or Printers and fax), right cklick on your printer -> click on "Print Preferences"(see pricture Fig. 1 ("Udskriftsindstillinger" = "Print Preferences"))
Now you get a new menu, cklick on "Adwanced" (see picture Fig. 2 ("Avanceret" = "Advanced")), then select "Greyscale" ("Gr?skala" = "Greyscale"), and then "OK".
All what i printed out after that, was in greyscale "colour".

...now you also have learnd a little bit danish too :o))
