1. If you are printing using postscript driver, try using PCL6 - printout would be darker for grey scaled items.

2. Print in lower resolution 600dpi or 300dpi, printouts would be darker.

3. Try printing all characters as black

You can adjust darkness at the printer using the console menu.
In the Configuration Menu ' Print Quality sub Menu , there is a parameter called Tonor Density. Factory Default is 3. Set to 4 or 5 to increase darkness..

The only thing to try is to run the cleaning software from 3-7 times, or until print quality is good. Right click the printer icon in the printer folder, select properties, then at the bottom click preferences. Locate maintainence, and run the clean and follow the instructions. If after 7 times the quality doesn't improve, you will have to replace the printheads. As long as the quality improves with each clean, continue to do so until it is acceptable.

Skipped Print Areas on Printouts

You may have a bad toner cartridge, if the cartridge has contaminants in it, it will not put toner on the drum in these areas, Try removing and giving the cartridge a good shake, try installing a new or at least another cartridge to see if the problem is here.

Hope this is of some help.
