INK LEAK CHECK
An ink leak check is required when disconnecting the Ink Supply Tube from the
Printhead.
The judgment method of the ink leak check is described below.
 Leak check procedure
1. Pull out the jigs for the leak check.
Figure 7-5. Leak Check Procedure (1)
2. Check the ink adherence state on the cloudy surface of the jigs to determine
whether or not there is an ink leak.
 Judgment criterion of leak check
Check whether or not ink is adhered at a position of 2 mm or more from the
leading edge of the cloudy surface of the jigs. (Consider the result to be a fail
if any of the jigs for the leak check does not pass the check.)
• Pass (no ink leak)
When ink adherence is less than 2 mm from the leading edge of the jig
• Fail (ink leak)
When ink adherence is 2 mm or more from the leading edge of the jig
