Cartridge Alignment
When to Align Cartridges
If you suspect that the plotter is not producing plots of the highest quality, you can run a
simple cartridgeĆalignment routine that will ensure that the print cartridges are aligned.
Perform this routine also after clearing a media jam.
The alignment is also automatically performed after each time you replace or reseat the print
cartridges. In this case, the plotter uses the first sheet of media that you load to perform the
alignment.
CarriageĆLED Calibration
The cartridgeĆalignment routine includes calibration of the carriage LED. This is the optical
sensor on the cartridge carriage, used to find the left and right media edges during media
loading. (This calibration is independent of the setupĆsheet calibration. The setupĆsheet
calibration calibrates the same LED, but the values stored are used only for scanning a setup
sheet and are separate from the values strored during the cartridge alignment.)
Aligning Cartridges
You do not have to enter service mode to align cartridges.
, With the plotter switched on, ensure the mediaĆjam
lever (pinchĆarm lever) is up and the window down.
The
Load Media
light should be on.
. Choose the correct
Media Type
on the front panel: If you are using plotting paper, as
recommended in the following step, turn the
Paper
LED on. The
Final
and
Draft
lights
have no significance for this procedure and either can be on.
A Load an AĆsize or A4Ćsize sheet of good quality plotting paper. (You can also use larger
media sizes.) The
Ready
LED lights up.
4 Press the
Align Cartridges
key.
The plotter takes 3 to 4 minutes to perform its alignment
routine using the sheet of paper you have just loaded.
In the course of the routine, it draws lines and shaded
areas and then ejects the paper.
5 Wait one minute for the ink to dry and unload the paper.
