4.3 Points to Note on Disassembly and Reassembly

4.3.1 Note: Items that should never be disassembled

Assemblies that should never be removed after initial factory adjustments, are indicated by the presence of red screws.
Under no circumstance should these red screws be loosened or removed. Removing these screws will render the printer out of alignment forever.

4.3.2 Moving the carriage manually

When moving the carriage, hold it by the handle [1] shown below.
Move the carriage as required during assembly and disassembly to prevent the carriage from contacting the parts to be removed.
You cannot move the carriage when capping has been performed. Refer to DISASSEMBLY/REASSEMBLY > Points to Notes on Disassembly and Reassembly
> Opening the caps and moving the wiper unit to remove the caps, and then move the carriage.
