Autofocus warning messages
• In connection with Autofocus, several warning and information messages may appear even if
the scanning job was otherwise finished successfully.
• Double-click on the yellow warning triangle in the Jobs window to read the message.
• Messages are shown in the following cases:
•If Autofocus is activated but ColorQuartet is unable to find a focus. In this
case, the program will default to the value found in the last focus calibra-
tion.
• If no focus calibration has been recorded for that drum.
• If the scanner cannot read the bar
code on the drum. If this occurs, you
can find the drum number by looking at the two digits before and two digits
after the two long lines in the middle of the code:
• Note that on older drums, the bar code may start to wear off and become
difficult to read. To order a new bar code label from your authorized Purup-
Eskofot dealer, please state the drum number. If the scanner cannot read
the bar code even though the label looks ok, the bar code reader may need
to be cleaned or adjusted. Contact your authorized Purup-Eskofot dealer for
technical support.
