Black Mark Hi, My brother accidently so he says pressed his finger on to the Acer screen and now there's this black mark type going from the top right to the bottom right and the colour around it is white- different to the rest of the screen. What is the problem and how do I fix it?

Only sounds as if he has damaged the pixels so much they don't display the colour properly any more, if it is still under warranty get it replaced by Acer, if not take it to an electronics store like pc world and they might be able to fix it for a price.

How do I access the question mark

All you have to do is hold the SHIFT key down and then press the BACKSLASH (/) key. This should allow you to access your question mark character.

Here is a link to an image of an ACER Keyboard:

Just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the information and items at the website indicated.

You can see the QUESTION MARK / BACKSLASH key near the lower right hand corner of the keyboard in that image.

I hope that was helpful to you, good luck and take care.

Just went to use my garmin 255w and screen is all garbled with a black mark and weird marks on screen. Is there anything I can do. Thanks

Looks like the screen is broken. Did it fall down? Did you carry it in a backpack and forgot about it?
If you turn it on and press with your finger on the screen. Does the mark move?

The label stock has black backing and when I try to calibrate the labels the printer doesn't seem to recognize the top of the form - why?

Black backing is meant to be used with the reflective sensor. This is the red light that you see in the "throat" when you raise the printhead. You need to change the sensor type in the printer from GAP or WEB to MARK. Press the SETUP key and then press NEXT until you see the setting for SENSOR TYPE. Change it from GAP or WEB to MARK. This will turn on the reflective sensor and then the printer will index from black mark to black mark.

Be careful though...setting in the printer driver usually override the printer settings so you may have to change the sensor type in the printer driver, depending on what software / driver you're using.

Hope that helps !

Trying to toggle from blue keys to white keys


You have to hold the shift key down and then hit the question mark key.


In the picture above the key is white but most of them are black. There are 2 shift keys at either ends of the keyboard with the trade mark up arrows on them.

Black mark on right side of paper

The scanner is not working properly, not the printer part of the unit.
The LED array is not lighting causing black scanned prints.
Resolder the contacts in the LED array...probaly a cold solder joint.

I bought an HD 32"LCD/dvd combo from Walmart on Nov 6, 2007 for my disabled brother. When I was visiting him last evening I noticed a thick black mark on the screen at the top right about 1 1/2...

I'm affraid that there is not much you can do to fix it.
The TV still under manufacturers warranty. Take it back to walmart to be repaired.

Black streaks on the fax

Yes it does, the rubber blade that cleans the drum is not doing its thing properly, hence leaving your mark, pull the drum unit out and expose drum by pulling back the cover underneath it, you should see your mark on the drum, don't touch drum with fingers or brush/clean it, it is photosensitive too so keep away from light for any period of time.
