1. Press Menu to open the MENUS.
2. Press to highlight DIAGNOSTICS, and then press .
3. Press to highlight PQ TROUBLESHOOTING, and then press .
The message PRINTING... PQ TROUBLESHOOTING appears on the control-panel display until the
printer finishes printing the PQ troubleshooting pages. The printer returns to the Ready state after
printing the PQ troubleshooting pages.
the pages it produces are individual colors, black, magenta, yellow and cyan and a white page and a config sheet.If the defect is on all pages then it might be a bad transfer belt. If it is only on one of the color pages, that will tell you which cartridge is bad.
