Cleaning Lazer

Many thanks to miguelovitch for telling me to take the top off the machine and clean the lazer...all we had to do was clean the little blue "eye" and the machine was fixed! I am so grateful.

Load disc and no disc is displayed continually.

Could be a dirty Lazer or a dying one. Use a cotten swab damped with eye glass cleaner and gently clean the Lazer eye. If problem consist then your Lazer might be dying.

why does it say no disc when clearly there is?

Some disc's are for certain regions only . Perhaps you got one for a different region and maybe it's just a bad one

CD plyer isn't working. It skippes or doesn't play the music. Could you tell me what to do? I would like to fix it mayself.

Try buying a cd/dvd player cleaner disk. This will clean the lazer eye. If it doesn't solve the problem clean the eye manually with a Q tip on a cotton swab. Make sure the device is unplugged.

My PS3 recognizes and plays music c.d.'s but will not recognize the games.

Simple, Lazer died buy a lazer from a reputable supplier, this one you shouldnt buy off of ebay (you dont know what you get or who has swapped there old one and sent back) not giving anyone a free plug but modsupplier.com has been good to me. So which one do i get you ask I will tell you lay the console down and put a disk in and watch it go in If it goes in without turning its a single eye lazer if it turns as it goes in it is a duel eye lazer. Here is the part that hurts single eye lazer is very expensive duel eye is about $80-100 weigh up if its cheaper to get sony to fix it if you fix it make sure you have no disk in it when you take it apart !!!! Yes it is easy to do Good Luck

Hello My printer(3100 cn dell) every time I


This means that loose toner powder has gotten in the way of the lazer "eye". If you open up the front door, you will see a blue tab toward the right, pull that toward you, then look on the right side of the printer, you will see that a door has opened. Pull that blue stick out as far as you can and you will see some toner powder on that, clear it off, and make sure the little pad is clean. After you have cleared the powder off, slide it back in and out a few times, this will clean the eye. Run another document through, if the line is still there, just clean another time. Should go away. I have this problem alot.
