5.4 ADJUSTMENT
This procedure is used for correcting media feed and printing position. This is done by mechanical
adjustments (head tilt) and firmware parameter adjustments. If this item is selected when X and Y excitations
are off, the X and Y excitations will be turned on and the initialization sequence will be carried out. Items for
adjustment are listed in Table 2-1. All these procedures are implemented during production.
When the head is replaced, head cleaning (followed by switching off and replacing the head), head rank
input, ink filling and print positioning are implemented. CW adjustment, reciprocal printing positioning and
zone delay compensation are carried out when the printing position is to be corrected after a change of
media type. If media feed is off, the media feed distance is compensated.
Item Details
Capping Position Adjustment To adjust capping position parameters in the firmware
Skew Verification To use sensor results to check for media skew
Head Rank Input To enter a specific value for a specific head and fill inks
Head Nozzle Verification After filling inks, to check head nozzle ejection by print results
Black Head Tilt Verification To check head tilt by printing (mechanical adjustment)
Colour Head Tilt Verification To check head tilt by printing (mechanical adjustment)
Repeatability Printing Positioning To align reciprocal printing position by printing
CW Adjustment To align the shafts of the two heads by printing and adjust left margin
Flush Pointer Adjustment To adjust the position for flushing into the flushing box
Media Feed Distance Compensation To print a line in the X direction and enter its distance (X resolution
adjustment)
XF-XR Sensor Distance To measure the distance XF and XR sensors with cut media
XF, Cutter-to-Head Distance To adjust top and bottom margins
Test Print To check head nozzles and adjust parameters (enter serial numbers)
Head Cleaning Done after manufacturing and before head replacement
5.4.1 Adjusting the capping position
This procedure is used for aligning the capping position correctly by adjusting the capping position
parameters in the firmware. When this item is selected, the printer carries out the home position detection
sequence and then automatically pushes the carriage against the maintenance unit to detect the carriage
position at that time. The position displayed is the distance from the home position flag.
Press [ENTER] to update the capping positions and move to “AJST: Measure High”, press [Back] to move to
“AJST: Home” without updating the capping position.
