1.2 Power-On Sequence
This section describes the power-on sequences for this product. The preconditions are as follows.
Normal power-on sequence
No error occurred at the last power-on, and the power was turned off normally.
Initial ink charge has finished and every pack has sufficient ink.
No paper on the paper path.
The Printhead is capped by the cap of the Ink System.
CR Lock is engaged normally.
This indicates the Simple Sequence.
PG position is set to PG 1.
Option Cassette Unit is not installed.
The following explains how to use the simplified diagrams in Table 1-1 or Table 1-2. The
diagrams show the movement of each component as seen from the front of the printer.
