Service Modes
Overview
Service Mode comes in 2 variations (which are not open to end users) as described below.
1. Download Mode
ROM can be upgraded in this mode. To enter service mode, invoke this mode first. Press
PAUSE Key once in download mode to enter standalone mode.
2. Standalone Mode
In standalone mode, strong cleaning, ink initial loading, Shipping the printer, Printhead replacement and
test printing (nozzle check pattern printing and settings printing), Printhead moving to print position are
functional. Service utility is also accessible from PC in this mode.
Differences between startup in the normal mode and startup in the standalone mode are as follows:
When service call error occurs because a Printhead failure occurs or the replacement timing of Purge Unit
/ Blade Cleaner / Transport Unit (mist absorber) is reached, Printer can be started in the standalone
mode so that these parts can be moved to the replacement positions using service utility.
<Differences of startup in standalone mode from startup in normal mode>
•
Initial cleaning is not performed at power ON.
•
When a print data error occurs, a Printhead ID error occurs, or Purge Unit / Blade Cleaner/ Transport Unit
(mist absorber) replacement timing is reached, the resulting service call error is masked.
Download Mode
