Printer ejects a blank page after appearing to print
Make sure:
•You remove the sticker and transparent tape from the backs and bottoms of the print cartridges. For help, see “Install the cartridges” on page 45.
•Your cartridge does not have clogged nozzles. Try cleaning the print cartridge nozzles. Follow the steps in “Improving print quality” on page 48.
Printer prints very slowly
•Close any software programs not in use.
•Check the document you are printing. Photos and graphics may take longer to print than regular text. Documents that are large or that contain background images may also take longer to print.
•Check the printer to see if another document is printing. Print jobs are printed in the order the printer receives them.
•Decrease the print quality setting to Normal or Quick Print.
Note: Higher print quality settings result in better quality documents, but may take longer to print.
