ACCESSING PENS
Press the Access Pens button to access the pen carriage when you need to replace, reseat, or
clean pens. The pen carriage will move into the platen area to allow easy access to the pens.
Each time the pen carriage moves out from its service station so that you can access the pens,
the pen nozzles are exposed to the air. If the pen nozzles are exposed to the air (except during
plotting) for more than a few minutes at a time, they are susceptible to clogging and drying.
Each time you remove a pen from its slot and then put it back, the plotter performs the pen
alignment procedure automatically.
REPLACING PENS
The pens should be replaced in response to a Pen Checking prompt or poor plot quality. Four
high-capacity ink cartridges are used in the plotter. Pen life expectancy is dependent on the
type of media and plotting mode used.
To replace the pens, perform the following steps:
Note
The four pens must be loaded in their designated pen slots in the carriage.
Use the color label on the cartridges and color dots on the carriage to match
positions. The plotter should be powered on when changing pens. If you se-
lected “Service pens” from the display, skip step 1.
