3.2.7 Ink Leak Check
This section describes the procedure for ink leak check necessary when disconnecting the Ink Supply Unit from
the Printhead or in a similar case.
Tools
 Ink Leak Measurement Jig (Parts code: TBD)
Battery type: CR2016 (3 V) x1

Do not touch or press the regulator located under the regulator protection plate of the Ink
Leak Measurement Jig.
 The Ink Leak Measurement Jig applies pressure by sending air using a syringe into the
ink path, and detects the variation of pressure in the ink path between the self-sealing
valve in the Printhead and the ink supply holes of the ink cartridges to check the
presence of ink leakage. If air leak occurs in the Ink Leak Measurement Jig, the leak
check itself cannot be done. Therefore, before performing the leak check, perform "Ink
Leakage Inspection Condition (p80)" without inserting the Ink Leak Check Cartridge to
the printer to test air leak from the Ink Leak Measurement Jig itself. (If the Ink Leak
Check Cartridge is not loaded to the printer, the valve in the cartridge is shut. Therefore,
the air leak check from the Ink Leak Measurement Jig itself becomes possible.)
 The ink leak check should be done with the ink tubes secured with the tube clamps and
the CR Cover attached after the joint section of the Printhead and the Ink Supply Unit
has been secured. (See "Ink Supply Unit (p42)".)
