Cleaning the Print Head

The EPI-4000 offers a print head cleaning cycle to ensure that all the print head’s ink nozzles deliver ink correctly. Whenever you turn on the printer, it performs a cleaning cycle automatically. The printer performs another cleaning cycle every 145 hours.

Under ordinary use, the EPI-4000’s automatic cleaning cycles keep the print head clean. If, however, you notice that the print quality is declining, you can run the cleaning cycle to clean the print head.

Note: Your ink cartridge will run out prematurely if you run the print head cleaning cycle often,

CAUTION:

•If you have persistent problems with print quality,, make sure you are using the right type of paper for the EPI-4000. See the section on choosing paper in Chapter 3.

•Do not follow the steps in this section to run the cleaning cycle when the display reads IL, the ink low message. If you run a cleaning cycle when the display reads IL, the display changes to 1E, the ink end message, and you cannot use the printer until you replace the ink cartridge.
