17. HOW TO ADJUST THE PRINT HEAD POSITION

17.2.2 Adjustment procedure for a spare print head

If the print quality becomes inferior after replacing the print head with a spare part, adjust the print head
position in the same way as the original one.
Step 1)
First, remove the original print head from the printer.
Note: Be sure to place the print head on a soft cloth or antistatic sheet.
Step 2)
Completely remove "Loctite" adhesive applied to the print head fixing screws.
Failure to do this disables accurate measurement of the adjustment value.
Note: DO NOT loosen the print head fixing screws at this stage.
Step 3)
Remove the print head fixing clip (green part) and check the adjustment value for the original print head
by fitting the jigs one by one, in the order from "±0mm" to "±0.4mm". Insert the positioning studs of the jig
into the positioning holes and the adjustment holes of the print head, and check which jig snugly fits the
print head.
Note: Do not push the jig hard against the print head. Doing so may damage the print head or the jigs.
