When installing the Printer Mechanism, be careful of the
following:
 Wipe off any ink on the joint portion of the Waste Ink Tube
before reconnecting the tube. Ink on the joint portion makes
the tube likely to get disconnected.
 As shown in
Fig.1-47, insert the Waste Ink Tube over the tube
of the Waste Ink Tray until the top end of the Waste Ink Tube
contacts with the rib.
Figure 1-47. Cautions of inserting the Waste Ink Tube
 Match the positioning holes with guide pins (two pairs) shown
in
Fig.1-46 (p.36).
 Tighten the screws in the order given in
Fig.1-46 (p.36).
 Make sure the Waste Ink Tube or cables are not pinched
between the Printer Mechanism and the Housing Lower.
 Route the CDR Guide Sensor Cable through the opening as
shown in
Fig.1-45.
