Question about Computers & Internet
I have lost the function image on my duplicator. The start up image is displayed and then nothing. I was in the image contrast mode when I tried to brighten the image. When I hit the up arrow it got lighter, when I hit the down arrow it got even lighter. Finally I hit the up arrow and the image was gone. Can you help restore the image?

Flyback transformers usually have 2 adjustable rods - 1 is for focus the other is for screen (G2) voltage. try turning Clockwise the Screen adjust with brightness-contrast at max. Till you see white diagonal lines, then go back until the lines disappear - then tune the brightness to your desired level.

Sounds like an extended desktop. have you tried dragging an open window (ie. internet explorer webpage) to the top, right, bottom, AND left? When you get to one of the edges, move it like you are moving it off and it should move to the other screen. You can change your setting to 'duplicate' your desktop in your video settings.

From your description, it sounds like an alignment problem. There are 3 LCD panels in the projector. Each one displays an exact duplicate image of the others except it's either red, green, or blue. Under normal conditions, the images precisely overlay one another so you get a sharp image. Due to age, heat, or vibration/shock(impact) it would appear that the red LCD panel has shifted a little, giving the "ghosting" effect. You'll have to have the unit repaired by a qualified tech. He'll have the special electronic equipment needed to align the panels properly. Before sending the unit in, try a reset in the menu. Sometimes, the projectors can shift the image electronically, using math algorithms which will try to auto-sharpen the display. Hope I was able to help!---Rick

Sounds like a bad drum cartridge. Pull the toner/drum cartridge out of the machine and set it down. Press down on a (blue?) tab to release the toner cartridge, and you can lift the toner cartridge out of the drum cartridge. There is a cleaning blade in there - a soft plastic blade that rides against the drum and scrapes off toner that didn't get transferred to the paper. If it gets stuck off the drum surface, images repeat a few inches (one drum circumference) down the page.
A new DR-350 drum unit should fix it. have the machine's power on when replacing it. While the door is open, touch the CLEAR key. The display will read "REPLACE DRUM?" or something like that. Press 1 for Yes.
