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.)
