QM7500 Technical Manual
Introduction This QM7500 Technical Manual provides you with complete maintenance,
troubleshooting and servicing information for the MSSC QM7500 Ink Jet Printer. It
also contains a replacement parts list.
CAUTION: This manual is designed for use by qualified technicians only. Any
unauthorized repairs will void your warranty. Unless you are a qualified
technician, do not attempt maintenance that is not discussed in the QM7500
Owners Manual (PN QM32004). You may accidentally damage components
resulting in injury or damage to the equipment.
For more information or assistance contact your local distributor or MSSC
Technical Support any time at (573) 437-7030; FAX: (573) 437-4030.\

Maintenance Startup
At beginning of each shift:
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.
Shutdown
If you are shutting down the 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 page 2.
If you are shutting down the 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 Preparing the QM7500 for Servicing
Before beginning work on the QM7500, follow these steps. Failure to follow these
steps may result in serious injury or damage to the unit.
To begin servicing the QM7500:
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 QM7500 and power supply to a well-lit, static-free workbench.
Special Notes for Reassembling the QM7500 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 retaining clip
offset is facing the valve board to prevent valves unseating from the valve board.
Finally, make sure that valves are properly oriented and seated in the valve board,
and that all wiring and tubing will not be kinked when the printhead cover is
replaced.
