Tip & How-To about Audio Players & Recorders

How to clean the lense on your CD or DVD player

If your unit has some time on it it probably has a dirty lense on the laser assembly. This isn't difficult to clean but you must exercise care not to damage any components of the laser assembly.

Unplug the unit. Remove the top cover. If the disc drive has a cover, remove it. You should see the lense, which looks like a fish eye, looking up at you. The lense is mounted on a set of springs and will move around as you clean it. This is normal but do not apply anymore pressure than necessary.

The alcohol will do the work loosening the dirt. Using 200 proof grain alcohol, and commercial grade, lint free, cotton swabs, (available from any electronic parts supplier, here is an example www.mcmelectronic.com ), moisten swab and gently touch the lense while rotating the swab head.

Use a dry swab after the wet one to remove the loosened dirt. Blow dry the assembly with canned air, also available at MCM. Reassemble unit and you should have a working player.

In the unfortunate chance that you still are not reading discs you could have a defective or weak laser assembly. This would have to be replaced with a new unit. I hope this has helped you.

my printer canon ir 2022 prints faints and blank pages, what can be a problem and how to fix it?


Hello,
first You must check, if the image is on the drum. To do these, start print and when you hear that paper is in drum section open the left door and look at the drum surface for the toner image on it.
i.e.
If the image is on it and it looks solid, check the transfer roller or replace him. Also clean the laser unit ( lenses and polygon mirror ) and change the drum unit. It can also be the problem with toner station.
i.e. the cylinder doesn't turns or the there isn't toner on cylinder.

It can be a bunch of things, so without seeing the machine it is difficult to say what is the problem... but, in most cases, the problem is in dirty laser unit or in transfer roller.

I have a bose lifestyle 12 that will not recogize all cds


Most likely you have a dirty laser lense. Disconnect unit from AC. Remove the case. Remove what you have to to expose the laser. It should look like a fish eye lookin up. Using 200 proof alcohol and a comercial swab (lint free) carefully clean the lense using the least amount of pressure possible. Blow any dust or residue off with canned air. Reassemble. Unit should work, if not the laser is probably bad and you need a new one.

Disc doesn't spin and player does not recognise disc


Generally when this happens you have one of two problems. 1) your laser lense is dirty or 2) your laser is shot. You didn't mention how old your unit is or how many hours are on it. To answer the first question......Unplug unit. Remove all cases until you can see the lense. Should be facing up and look like a fish eye. Using 200 proof alcohol and commercial swabs (lint free) moisten swab and gently clean lense. Use as little pressure as possible and be very careful. Blow lense and assembly dry using canned air. Reassemble and if all went well the unit should work. If not you probably need a new laser assembly which means you need a new unit. Price to replace would be as much or more than a new unit. Hope this helps.

i recently got windows 7 and i have a hp 2605dn laserjet printer. for some reason, pictures with red are faded. just replaced with a new cartidge and still have problem is there any special color settings i should have


The recent Windows 7 is probably just a coincedence.

This is a common problem on these printers.

Cause is dirty lenses and or mirrors in the laser unit.

Solution is remove laser unit, open it, clean lenses and mirrors (very carefully to avoid disturbing alignments, and scratching).

The laser unit is deep in the printer, so it's quite a lot of work, but very rewarding when you've fixed it.

Alternatives - buy a replacement laser unit and swap and clean old one at leisure, or get an exchange refurb printer - if you think your mechanical skills arn't up to it.
