2.3 Disassembling and Reassembling the Printer

Precautions during disassembly/reassembly are given below. Refer to the Parts Catalog
for the disassembly procedures. In the Parts Catalog , illustration numbers are in the
order of disassembly.

2.3.1 Carriage lock release

When the printer is properly turned off with a cartridge installed in the carriage, the
carriage is locked in the carriage capping position.
When the printer can be turned on normally, the carriage will be unlocked. However,
when the printer does not operate properly, it may be necessary to unlock the carriage
manually. The carriage lock can be released by removing the cartridge and, while
pressing the lever of the purge unit, moving the carriage toward the left.

2.3.2 Removing tap screws

The printer unit and the base are attached with tap screws. Mold scrap from the
tapping process may still be adhered to removed screws. Using those screws as-is may
strip screw threads on the mold side. When reusing screws, remove the mold scrap
completely or use a new screw.
