3.3 Disassembly and Reassembly
See below for supplemental information and cautions for disassembling and
reassembling the printer.
Refer to the
Parts Catalog
for the disassembly procedure. The illustrations in the
Parts
Catalog are numbered according to the order of disassembly.
3.3.1 Carriage lock release
NB: When releasing the carriage lock of the S900/S820, it is necessary to remove the
printer unit from the bottom case unit.
Normally, when a cartridge is installed on the carriage and the power is turned off, the
printer moves the carriage to the capping position to lock it. When the power is turned
on, the carriage lock is normally released. However, if the printer does not operate
properly, you can release the carriage lock manually.
On the front of the printer, rotate the gear as shown by the arrow in the illustration
below to release the carriage lock.
