The soution given is misleading, the Lexmark printers use a Photoconductive drum (photoconductor) or often abbreviated to PC.
They obey standard EP image formation process, as such the drum is charged by the charge roller, the charge is dissipated by the laser (striking the PC), toner is attracted to the PC where the charge is lost and the transferred to the media by the transfer roller. Standard 6 stage EP formation process

The reason the laser does not strike the paper directly to reduce charge, where is the charge going to go ? With the PC the charge tunnels vertifcally to the aluminium core, paper is an insulator so the process cannot work.

Anyway, when replacing the PC in the E342 you need to reset the PC counter.
Power the printer off
Hold the DIamond shaped button (return) and power on
release the button when "Performing self test" is displayed
Select "Reset PC count" and press Select, the counter will Zero.

If this does not work
Power up while holding Return button but have the front access cover open
Close the cover once "!" displays, you can print the menus by holding the select button then until they print out.

I do not know of any Lexmark Laser printers that contain a photo conductor.

Lexmark engines use a "Write Black" process. This means that the charge roller will charge the paper and the laser will discharge the area that it wants the toner to adhere to. At least I believe that it is a Write Black process.

Regardless of the process, there is no photo conductor. The imaging of the page is the function of the laser.

What exactly is the failure you are trying to solve.

My 343n is printing faint on one side does anyone know why, we have 80% toner and 28% left on the photoconductor life

Try to use different supplies - if you have another toner and another PC kit. If the supplies are working fine, it could be the transfer roller that's causing the faint prints. I would suggest cleaning the transfer roll with a soft cloth. If problem continues, you might need to replace the roller.

It says replace photocon, what is that ?

That is an organic drum that the laser writes to, and which transfers the toner to the paper. After a given number of prints, these need to be replaced, as they get scratched and worn out.

Unless you are having problems with the printer, (or this particular model locks down the printer), you can continue to use it as is. The only problem you will notice is that your print quality is going to start to degrade; eventually getting lines and/or a grey shading in the background of your prints.

You should be able to purchase a Photoconductor kit through whomever you normally buy your toner from, or from a local dealer that sells Lexmark printers. They can also be purchased online and many different locations.
