There are two side of the Filter for the HM1C, an inlet side and a outlet side.  Here the Inlet side has been marked to make it easier to see.  In the future, all filters from SWF East will be marked this way.

To change the filter without making a mess, make sure that the circulation pump is powered o. Because the HM1C turns the pump on by itself when doing automatic head cleanings, it is a good idea to turn o the upper unit of the printer before proceeding with the Filter change. Flip the power switch to the down position. This power switch should always be left o.See Figure C.

It is important to understand how the ink ows through the circulation system. See Figure B. If the lter is put onto the HM1C backwards then it will slow the ow of ink to the head and clog the lter a lot faster than it should.

To remove the lter, disconnect the outlet side rst. Then attach the new lter’s outlet connector. Then you can remove the inlet side connector, and twist it onto the new lter.

Last Chance Filters need to be changed approximately every four weeks, depending on the amount of printing done. Failure to change these lters on time can cause poor nozzle checks and even clogs in the WIMS system. Last Chance Filters are available from: colmanandcompany.com.
