(6) Open the ink cartridge cover.
(7) Remove the five screws from the upper cover.
(8) Lift the upper cover up and off the lower cover.
NOTE:
When lifting up the upper cover, do not put your hands in the opening above the
platen (shown below). Doing so may damage or stain the CR encoder strip inside.
Assembling Notes:
• When mounting the upper cover:
- Make sure that the jam clear cover is not mounted.
- Make sure that the ink cartridge cover is open
- Make sure that the head/carriage unit is placed in the head capping position (home
position). This prevents the ink supply tubes from getting crushed between the upper
and lower covers.
- Take care not to deform the PF encoder disk
• After mounting the upper cover, check that the PF encoder disk is not bent or deformed
through the peep hole. (See the illustration above.)
