This printer has both a USB and parallel printer connection.
I suggest you connect this printer to your computer using the USB printer cable and install the printer driver software on your computer.
You can download the Lexmark printer drivers from theirsupport WEB site. Please click on this link and select your model printer todownload :- http://support.lexmark.com/index?page=home&locale=EN&userlocale=EN_US&segment=DOWNLOAD

This might be an issue with the duplexer. Please contact Lexmark Technical Support center.

IN the setup menu of the printer is a setting to disable the audible alarm.
Press > or

hold the go and return buttons while powering up the unit it will come up to registration hit select this is where you adjust the laser lock of the scanner

i take it that your getting an invalide engine code error? this is caused usually by the printer taking a power surge. you can get a batch file from lexmark to reflash the engine board however if it will take the code it usually odesnt last to long. change the engine board and your problem will go away

do you get 5 beeps when the printer powers up? three things can cause this the control panel, the logic board and the engine board if you have replaced the logic board the engine board is the problem change that and your problem should go away

Printer is Posting a 953 or 954 Service NVRAM Failure Message ID: ENUS9756
To clear an NVRAM error message: 
Turn the printer off. 
Leave it powered off for at least a minute to give it a chance to reset, then power it back on. 
If that clears the error, continue using the printer but keep an eye on it for the next day or two to see if the error returns. If the error does not return, the printer should be fine.
If the NVRAM error does return, you can try resetting the printer's NVRAM as follows:
Turn the printer off. 
Now press and hold down the right Menu arrow button (>), the Select button, and the Go button at the same time. 
While continuing to hold all three of these buttons down, turn on the printer. 
Keep holding down the buttons until the printer displays Clearing NVRAM or Restoring Factory Defaults, indicating that the printer is performing an NVRAM clear. You can release the buttons at this point. WARNING! Do not power off the printer during this process. 
When the printer has finished the NVRAM clear, it should return to the Ready mode. 
If the printer has not gone back to Ready after fifteen minutes, turn off the printer and then turn it back on again as you normally would.
If these steps do not clear the NVRAM error, there may be an issue with an installed option on the printer. Electrical options (like flash memory, network cards, code SIMMS, and additional RAM memory) are the most likely causes. To see if an installed option is causing the error: 
Turn off the power and remove any options that have been installed. (For information on removing memory or code SIMMs, click here.)
Turn the printer back on.  
If the NVRAM error continues, the printer will probably need service. 
If the NVRAM error is gone after you have removed all of the options, power off the printer again. 
Reinstall the options one by one. Power on the printer each time to see if the NVRAM error returns. 
If the NVRAM error returns as soon as you reinstall an option, that option may be causing the error. 
Remove that option. 
Turn off the printer and reinstall all remaining options (if any). If the NVRAM error appears only when that one particular option is installed, that option may be defective or incompatible with the printer. 
If you can reinstall all of the options and the NVRAM error is gone, an option may have been loose and simply needed to be reseated. Again, keep an eye on the printer for the next day or two to see if the error returns. If not, the printer should be fine.

the top roller is the charge roller and the bottom one is the transfer roller if a foriegn substance got on either roller they could create this problem the oil from your fingers getting on them could create this. given everything youve changed the rollers are whats left. you can clean the charge roller but its better to get new ones these are consumable
