Printhead cleaning mode (PH CLEANING)

Use this option to select an automatic printhead cleaning mode for the selected media type.

Parameters:

START & END — Performs cleaning at the start or end of the print based on the print history record.

DURING PRINT — Performs cleaning after a certain period of time even during printing.

NOTE DURING PRINT can cause some banding.

NOTE When the TENSION winding or BACK & FWD (MEDIA ADV MODE mode) is
selected, the printer will only use START & END even if you have selected DURING PRINT.

When you select DURING PRINT and cleaning has interrupted printing of an image, the media
will feed back so that the image that was being printed before cleaning started, can be
continued. The amount of back feed can be set through the BACK ADJUST VAL option.

Media back feed adjustment (BACK ADJUST VAL)

This option sets the amount of back feed when printing of an image is interrupted by the automatic
cleaning process.

Set a back feed adjustment value for the media based on the back feed adjustment pattern. See How
do I...Calibrate the printer.

Parameters: ±2000 pulses (+5 mm), 1 pulse=2.5 µm

Hint After printing the back feed adjustment pattern, measure the start distance. Try setting
the value at 0005 and reprint the back feed adjustment pattern and re-measure the distance
and modify the value if necessary. Increasing the value will increase the distance.
