If print cartridge is exposed to air for an extended period of time, a
layer of dried ink will form a crust on the nose of the print cartridge. If
this occurs, follow the steps below to remove the dried ink from the
nose of the print cartridge.
1. Hold the print cartridge over a waste bln so that the nose of the
print cartridge is pointed toward the waste bin.
2. Gently scrape the dried ink with the edge of a 80mm x 130mm
business card or other rigid paper stock so that the dried ink falls
into the waste bin.
