Cleaning the print cartridges

Maintaining the printer

4 Maintaining the printer

To maintain the best possible print quality, you can use PDAs running the Palm OS or Pocket PC to perform

printer maintenance tasks, such as cleaning and aligning print cartridges and calibrating color.

Cleaning the print cartridges

If printed characters are incomplete, or if dots or lines are missing from the printouts, you might need to

clean the print cartridges. These are symptoms of clogged ink nozzles, which can result from prolonged

exposure to air.

NOTE: Before you clean the print cartridges, make sure the print cartridge ink levels are not low or

empty. Low ink levels can also cause incomplete characters, missing lines, or dots on the printouts. Check

the print cartridge lights to make sure they are not on. (For information about printer lights, see the

onscreen user’s guide for the printer.) You can also check the status of the print cartridges from the

Toolbox. (For more information, see Viewing printer status information.)

Replace any low or empty print cartridges. For instructions, see the onscreen user’s guide for the printer.

To clean print cartridges automatically

NOTE: Clean the print cartridges only when necessary. Cleaning uses ink and shortens the life of the

print cartridges. There are three levels of cleaning available. After one level of cleaning, perform the next

level of cleaning only if the results are not satisfactory.

1. Open the Toolbox. (See Opening the Toolbox.)

2. On the Services (Palm OS) or Printer Services (Pocket PC) tab, tap Clean Print Cartridge, and then

follow the onscreen instructions.

To clean print cartridges manually

Poor contact between the print cartridges and the print cartridge cradles can also affect the quality of the

printout. When this occurs, try cleaning the electrical contacts on the print cartridges and print cartridge

cradles.

For information about cleaning print cartridges manually, see the onscreen user’s guide for the printer.
