Calibration

If, for example, yellow is aligned downwards (G) at plus 4 with cyan, then add the

determined 4 to the cyan reference value of 10 and enter "14" in the settings for yellow

printing downwards.

G - Vertical offset from magenta to cyan in the range of +/- 5 pixel at 300 DPI

H - Vertical offset from yellow to cyan in the range of +/- 5 pixel at 300 DPI

I - Vertical offset from black (key) to cyan in the range of +/- 5 pixel at 300 DPI

J - Vertical offset from cyan printed upwards to cyan printed downwards

K - Vertical offset from cyan printed upwards to magenta printed downwards

L - Vertical offset from cyan printed upwards to yellow printed downwards

M - Vertical offset from cyan printed upwards to black (key) printed downwards

9.3 Printhead Replacement

Place the disassembled printhead unit on a clean, dry and flat surface.

Remove the tubing sheet metal flap at the front left and close all plastic hose clamps

with 4 clicks each.

Remove the electronics sheet metal flap at the front right.

Locate the small 4-pin plastic connector housing to the left of the corresponding

angled PCB and carefully pull it out of the socket. Do not pull on the cable, but only

on the connector housing!

Use the short side of the 1.5 mm Allen wrench and carefully lift the corresponding

angled printhead PCB on its left side (see figure).

After the angled PCB has been pulled out of its connector on the left side (A), it can

also be removed from its fixation (B) on the right side to the left (C).

Using two fingers, carefully lift the two small plastic frames - that hold the printhead

FCC cables in place - one after the other about 2mm.

Once both frames are unlocked, the FCC cables can be easily pulled out of the

connectors.

Put the angled PCB aside until the new printhead can be mounted.

Completely remove the two M3 screws from the left and right front of the

corresponding printhead.

Insert the two supplied M4 screws into the now visible threaded holes by turning

them 3-4 times.

Lift the printhead at the front by approx. 5cm and place an object underneath. This

prevents ink from leaking out of the ink bag when the tubing is loosened.
