◆If a line segment is missing or broken, the jet listed in the same column is out. In Fig. 4-21,jets 263 and 265 are out.

◆If a line segment is marked with a code letter, it has already been detected by the software, so no further action by you is required. This data, however, may be requested by MacDermid ColorSpan Technical Services (phone: 800-925-0563) to help diagnose printing problems.

Note

If this test auto-detects (marks with an E) that more

 

than twelve jets are missing on any one printhead,

 

the printhead may be improperly seated. Try reseat-

 

ing the printhead, and print another Jet Coverage

 

pattern.

 

 

7.When the calibration pattern has printed, the control panel displays a menu with the following options:

◆Report individual bad jets — enables you to report a bad jet.◆Clear individual bad jets — enables you to clear (mark as good) a jet.

◆View current bad jets — lists the bad jets on a given printhead.
