Maintenance The HP DeskJet 300 Series printers do not require any scheduled maintenance. Periodic cleaning, however, not only enhances the look of the printer, but also maintains it in optimum condition. Cleaning may also make it easier to diagnose a problem visually. Maintaining Print Cartridges In order to maintain optimum print quality, the printer automatically performs the operations of "spitting", wiping, and capping the print cartridge nozzles. These operations are not visible to the user and require no user intervention. Although print cartridges require no routine maintenance, proper use and handling of them will help insure optimum print quality and print cartridge life. Read "Print Cartridge Tips" in this section for tips on using and handling the print cartridges. Note See "Troubleshooting Print Cartridges" and "Solving Print Quality Problems" in chapter 6 for more print cartridge troubleshooting information. Warning The print cartridge ink contains diethylene glycol which may be harmful if swallowed. Keep new and used cartridges out of the reach of children. If ink is accidentally ingested, contact the HP Health Line (800) 457-4209 in North America. From all other international locations the HP Health Line can be reached by calling (503) 494-7199. For health related issues, this line is staffed 24 hours per day. Print Cartridge Safety Ink used in the print cartridge does not pose a health hazard to customers. During the development of ink formulas, all the ingredients are screened and researched for known potential health related issues. Only those chemicals that meet or exceed worldwide safety and regulatory requirements are used in HP inks. Cleaning the Print Cartridge HP DeskJet 300 Series printers automatically carry out "spits and wipes" to help maintain the print cartridge. These printers also have a print cartridge cleaning routine to restore print cartridges to optimum functioning. See "Using the Print Cartridge Cleaning Routine" in chapter 6.
