Storage MX or XR print heads
Store the MX or XR print heads under following conditions:
When a print head with ink is stored or not used for more than six months, ink deposits
may form, which can result in the clogging of different nozzles.
In this case, fill the print head with fresh ink before using.
Procedure:

Leave the nozzle plate closed with the nozzle locking clamp!

Remove the feeder tube on the head and pump the old ink out of the ink supply
system

Then remove the return flow from the ink system and pump the old ink out of the
print head

Finally, rinse out the head and resume operation
Customers having replacement heads in storage should rotate them every three months.
In this way, the customer has a regular control over the functional integrity of his print
heads.
All print heads must be tested once before installation
Before storage of the MX or XR print heads the ink bottle must be taken out and stored
according the storage instructions given below ink bottles.
The print head must be closed with the nozzle clip and the air inlet of the ink system
must be closed with the plastic plug. Close the ink filler opening (bottle) with the screw
cap. See also Disassembly of the print head
