Power-On Sequence
This section describes the power-on sequences, detailing the conditions and operations involved from turning on the printer to the final readiness state. It includes steps for checking waste ink overflow, avoiding deadlock, checking CDR tray sensor, releasing CR lock, seeking home position, resetting APG, initializing PF motor, and detecting ink cartridges.
Standard Operation Time
This section provides the standard operation time for servicing the product, broken down by parts/units. It lists the time in seconds for replacement and adjustment, along with the total time required for each component.
