6.1.1 Draining the Ink from the Ink Tubes
--This must be performed before removing the print head unit or engine unit--
(1) Plug the power cord into the outlet.
(2) Make the machine enter the maintenance mode by pressing:
Menu/Set, *, 2, 8, 6 and 4 keys in this sequence.
(3) Pull the release lever towards you and open the scanner unit. On the underside of the scanner
unit, turn the scanner open sensor actuator towards you and keep it depressed with adhesive
tape.
This prevents the machine from detecting that the cover is open.
(4) Open the ink slot cover and pull out all four ink cartridges.
NOTE: Be sure to perform steps (3) and (4) in that order. Performing step (4) before step (3)
will cause Function code 76 not to be enabled in step (5).
(5) Carry out initial purge with Function code 76 + 9 key + FAX Start button.
For details, refer to Chapter 7, Section 7.5.18 "Purge Operation."
