parameter in print control software unmatched with current
ink type
From:
Regional Sales Department, Global IP Sales Center
Classification:
There is an information of troubleshooting regarding poor print quality by unmatched
between parameter in print control software and actual installed ink type.
Symptom
There are different image processing parameters for each ink type in Pro TF6250.

parameter in print control software.
If dot pattern or image alignment is not problem but banding or uneven density may
occur, then check the parameter in print control software whether it is matched with
actual installed ink type.
How to Check
・Check the Connection between PC and Machine
・Start print control software (if already started, close it once and then restart)
・Check the parameter below
