Handling Position

CAUTION

□ When lifting up "Printer Mechanism", "Lever, Change" and "Combination Gear, 27.2, 19.2" may detach and drop. Take care not to drop and damage them.

□ When lifting up "Printer Mechanism", take care not to leak and drip ink from the end of "Waste Ink Tube" ("Waste Ink Pads" side).

□ To prevent "Frame, Main" from warping, do not lift "Printer Mechanism" holding the places which are not specified to hold.

When installing "Printer Mechanism" to "Housing, Lower", pass "Waste Ink Tube" through the hook indicated in the figure below, and securely set it in the groove, so that "Porous Pad, Ink Eject, Upper, Support" will not float from the tube. If installed insecurely, it may cause the ink leakage.
