Carriage and Scan-Axis Problems
1. Printhead continuity problems.
When installing the Ink Tubes System, it is possible that the crane
(the part of the Tubes System that is connected to the front of the
Carriage) is not clipped properly. This can cause Printhead continuity
problems afterwards, especially in the light cyan and light magenta
Printheads (XX16 REPLACE message appears for these Printheads).
n Whenever there is a Printhead continuity problem, always check
that the crane is completely clipped to the front of the carriage.
2. Unknown Line Sensor ID.
When performing the Scan-Axis Calibration, the Printer asks for the
Line Sensor ID. But there is no label on the Line Sensor indicating it.
n If the Line Sensor ID is not indicated on the Line Sensor, use the
default value which is "0". In the future, if the LED’s are
modified, a sticker will be included with the new Line Sensor ID.
3. Line Sensor is shown as "Not calibrated" in the Service
Configuration Print.
This is a firmware bug. It is possible that the Line Sensor is
calibrated even though the Service Configuration Print indicates
that the Calibration has not been performed.
n Just ignore this information about the Line Sensor calibration.
n If there are any errors related to the Line Sensor, perform the
Scan-Axis calibration to make sure that the Line Sensor
calibration is completed.
Media-Axis Problems
1. Printer unloads media (it suddenly starts to rewind and unloads the
media)
If the window was raised at exactly the same moment when the
Printer moved the media (e.g. during media loading) from that
moment onwards the Printer will always reject the media unless the
Printer is turned OFF and then back ON again.
n Problem disappears after re-booting the Printer.
NOTE This problem is solved in any A.02.xx firmware release.
