10.5.1
FC05 Gutter Clipping
Diagnosis
This fault is also known as "gutter catch" and is similar to the associated problem of Printhead Cover
Catch. The problem occurs when the least deflected drops clip the gutter and are thus not printed.
If the jet is misaligned on the gutter, the least deflected drops may catch the edge of the gutter. This will
cause the loss of the drops from the top of the print pattern.
As printing continues, the ink will build up on the gutter edge and the print loss will increase, sometimes
leading to deflector plate shorting and EHT failures.
The following diagram illustrates the problem:
This print sample shows gutter clipping, resulting in loss of the top part of the print.
Cause and Cure:
Check the EHT settings (see - "Changing the System Setup"). Check the jet alignment.
FC06 Printhead Cover Catch
Diagnosis
This problem is caused by the most deflected drops catching the edge of the exit slot in the printhead
cover, and thus failing to be printed.
The following diagram illustrates the condition:
