LEXMARK 2004 SERIES.PRINTER NOT PRINTING DOWN RIGHTHAND SIDE,ONTO COPY.

There is a firmware update for the Lexmark Pro900 Series printer that addresses print quality issues. Please visit the Lexmark website to download and install the Lexmark Pro900 Series Firmware Update.
After successfully updating your printer, try to print, scan or make a copy again to verify that the problem is fixed.
Should the problem continue, it might be a printhead problem. Please contact Lexmark Technical Support Center for further assistance.

Try to unplug and replug the printer into the power source to reset it. When the printer turns on, try to copy 2-sided again. Refer to the Lexmark 7500 Series User's Guide for the step-by-step instructions on how to copy on both sides of the paper.
Notes:

• Use only plain paper in Letter or A4-size. Do not make duplex copies on envelopes, card stock, or photo paper.
• You cannot print duplex through the PictBridge port.

Hmm...Likely a driver issue. Try downloading a new driver (more up-to-date. Remove the old driver first (Need help? Look on the net for 'Removing Printer drivers') I suggest unplugging the printer before installing the new driver as well.
Here is the driver site:

Lexmark uses a dedicated 'Print spooler' that may be having issues. Ask a techy friend for help with this.

Hello,

Specs say 10PPM black and 8PPM color in quick mode.

If you use higher resolution it will be reduced accordingly.

Refer to:

Z600 Series Specs

That is for a Z601, but the 600 should be the same.
