6.7.1.4. Cleaning Crusted Ink from Print Cartridge Nozzles
Storing an uncapped print cartridge outside of the service station can cause a crust of ink on the nozzles.
Do not install an ink-crusted print cartridge into the product.
Caution:
Use care during cleaning to avoid staining your hands or clothes with ink from the print cartridge.
1. Hold the print cartridge by the top of the cartridge.
2. Scrape dried ink off of the orifice plate into a trash container, using the edge of an index card or other
rigid paper stock (see Figure 6.11.4).
3. Follow the host printer's instructions to initiate a printing self-test to produce a page of printed informa-
tion.
• If dots are not missing toward the end of the printout, the print cartridge was successfully restored to
operating condition.
• If dots are missing toward the end of the printout, removing dried ink did not restore print cartridge
operation. Replace the print cartridge.
