1.6.4 Ink Smudge Prevention Mode

When the printer is in this mode, the carriage remains at the edge of the carriage for extra time before
each return. This extra time allows ink to dry enough to avoid ink smudges caused by bleeding and ink
contact with the paper. Note this function is designed as a response to any customer's complaint and is
not described in the user's guide. Also, it is necessary to acknowledge to customers in advance that this
mode does not provide the fastest throughput for the printer. The printer goes into this mode when you
press the Cleaning (Black) and Cleaning (Color) buttons while turning on the printer.
