I have a Lexmark Z53 Color Jetprinter. It worked fine in the past, but has recently started printing blank pages. This occurs whenever I try to print any type of document (Word, PDF, etc). So far, I've made sure that there is ink in the printer, I've checked the cable connections (it's attached by a parallel port), and I've gone through the troubleshooting steps in the Lexmark knowledge base (I removed the tape from the cartridges and I cleaned the cartridge nozzles with a clean print nozzle test). My OS is Windows XP, and there haven't been any error messages. I'm not sure what steps to take next. Any insight would be great!
