M) Pump does not run
* Remove transformer power cord from unit and check for proper AC
voltage at connector. (See Troubleshooting Chart at end of this list.)
Replace transformer if defective.
* Remove front cover and check electrical connectors on pump. If proper
voltage is present at pump and pump is not running, remove wires (2) going
to pump, and check resistance across pump coil (See Troubleshooting Chart
at end of this list.)
* If no voltage is present at pump connectors check transformer and AC
outlet.
N) Ink leaks from ink bottle cap
* Remove brass connector and check for presence of “O” rings on the under
side of brass connector and replace if missing or damaged.
* Tighten container cap.
* Reposition container and check for leaks.
* If leak continues, replace bottle with a new one and retest.
* If leak continues, replace ink bottle cap assembly.
O) Product delay/character width changing on
product
* Check the orientation of box to MICROJET — it must be perpendicular.
* Clean photocell filters with water, and check that both photocell LED
lights come on when product passes by. If photocell LED does not come on,
go to procedure “G”.
* Check to insure no extraneous spaces are inserted before or after text in
message. If so, delete extra spaces.
* If problem continues, check for dark colored bands on box. (Photocells
will not detect black). Test with a blank box.
* If product delay/character width continues to move, call for service.
