2.2.3 Disassembly Flowchart
This section describes procedures for disassembling the parts/units in a flowchart format. For some parts/units,
detailed procedures or precautions are provided (accordingly indicated by icons and cell's color). Refer to the
explanations in the example chart below and perform an appropriate disassembling and assembling procedure.
(See "2.3 Detailed Disassembly/Reassembly Procedure for each Part/Unit (p38)".)
For routing cables, see "2.4 Routing FFCs/Cables (p46)".
2.2.3.1 Parts/Units whose Configuration is Different between Models in the Flowchart
The models describe in this manual employ the same printer mechanism but they have different printing related
functions and structures. Therefore, the parts/units vary and the shape of them differs even they have the same
parts name.
In the flowchart in this section, the parts are in two colors: black for the common parts or units, and blue for the
parts or units which differ between models. For the parts or units which differ between models, confirm the
composition of the parts for the printer whose disassembly procedure you want to check, and then see the
disassembly flowchart.
Note: The 2nd Cassette Unit is installed for WF-4640 series, and option for WF-5690/4630/5620/5190/5110 series.
