4 Getting Help When Things Go Wrong Why won't it print? continued What is the problem? Possible cause To solve the problem... A blank page came out of the printer. The printer is really slow. You may be out of ink. You may have forgotten to remove the vinyl tape from the print cartridge. You may be trying to print a fax. Your computer may have less than the minimum system requirements. Too many software programs may be running at the same time. You may be using outdated printer software. You may be printing a complex document containing graphics or photographs. 1 Lift the printer's cover and verify that the print cartridges are installed properly. 2 If you are out of ink, replace the print cartridge. See "Replacing Print Cartridges" on page 27. 3 Print your document again. Make sure you have removed the protective piece of vinyl tape on each of the print cartridges. See "Replacing Print Cartridges" on page 27. 1 Save the fax in a graphic format, such as TIFF. 2 Place it in a word processing document and print it from there. 1 Check the amount of RAM and processor speed in your computer. See "System Requirements" on page 52. 2 Free up some space on your hard drive. Having less than 100 MB of free space on your computer's hard drive can mean longer processing times. Close all unnecessary software programs. Check the printer driver you are using. Be sure to check the HP web site at http:// www.hp.com/support/home_products for the most recent software updates. Be patient. Large, complex documents containing graphics or photographs print slower than text-only documents. 36
