I have Dell computer, Windows XP 98 Home Edition and A940 printer, circa 2002. The printer stopped printing, and also won't copy. There have been no error messages and the printer shows that the cartridges are almost full. Through printer troubleshooting I was able to print out a complete test page and black and color printing was fine. I have turned the printer off, unplugged it totally, waited, put it all back together, taken out and replaced the printer cartridges, run a test alignment which was partially successful, but then it wont copy a page I put on the screen, or print a document. I uninstalled the printer and reinstalled it, turning everything off as necessary. The printer "thinks" it's printing out but the pages are blank....and yet that troubleshooting test page was fine. I am using a refilled Series 2 black cartridge and an original Dell color cartridge. Any ideas?
