Maintenance
Startup Procedure
At the beginning of each shift, perform the following tasks:
1 With the spray cap on the solvent bottle, spray the nozzles with
solvent. In harsh environments, you may need to spray the nozzles
more often than once per shift.
2 Purge the printhead.
3 Check the ink level in the bottle; install a new bottle if necessary. In
harsh environments, or if print quality declines, replace the ink bottle
with solvent and purge solvent through the unit.
2
Shutdown Procedure
If you are shutting down a porous unit for less than two weeks, simply
turn off the controller. You do not need to purge the printheads with ink
or solvent. Also, do not remove any ink that may have caked on the nozzle
block. This will keep contaminants from entering the nozzles.
When you restart the unit, follow the daily maintenance procedures on
“Startup Procedure” on page 2-1.
If you are shutting down a porous unit for more than two weeks purge the
printheads with porous solvent. Leave the solvent in the ink lines until
you restart the unit.

Servicing Procedures
Preparing the QM1610 for Servicing
Before beginning work on the QM1610, follow these steps. Failure to
follow these steps may result in serious injury or damage to the unit.
To begin servicing the QM1610:
1 Remove the ink bottle.
2 Cover the front of the printhead with an absorbent cloth and purge
the printhead to remove any ink from the system.
3 Remove the QM1610 and power supply to a well-lit, static-free
workbench.
5
Special Notes for Reassembling the QM1610
Printhead
Make sure the regulator is properly seated in the saddle of the printhead
base to allow proper connection of ink bottles. Also ensure that the valve
supporting pins are installed properly to prevent valves unseating from
the valve board.
Finally, make sure that valves are properly oriented and seated in the
PCB, and that all wiring and tubing will not be kinked when the printhead
cover is replaced.

Backflushing a Nozzle
1 Prepare the QM1610 for servicing. (refer to “Preparing the QM1610
for Servicing” on page 5-1.)
2 Remove the printhead bottom cover by removing the three screws
from the bottom of the printhead. With the unit flat on the workbench,
place your thumb on the regulator and press down lightly as you lift
up the Bottom half of the printhead.
Note: Hold the components in place with your finger if necessary. Make sure
the inner assembly remains in the printhead top cover. Also, avoid
unnecessary flexing of the inner tubing and connected cable to prevent
damaging the connections.
3 From a print sample, locate the nozzle that needs backflushing.
4 Disconnect the tubing connected between the valve and the nozzle
from the valve end only; allow it to hang free.
EQUIPMENT DAMAGE. Remaining ink pressure may cause ink to
shoot out of the tubing.
5 Place a cloth at the open end of the tubing.
6 Install the cleaner assembly nozzle (from the service kit) on a bottle of
solvent.
7 Press the solvent bottle against the clogged nozzle and spray solvent
through it for several seconds.
8 Reconnect the tubing to the valve.
9 Replace printhead bottom cover, remount, and purge for several
minutes.
