REPLACING A MAG READER AND CABLE
Before changing the mag reader, use a cleaning card to ensure that the head of the mag reader is
free from dirt.
Insert the cleaning card with the fuzzy side facing down. Remove and re-insert the card several
times. Turn the card around (fuzzy side still facing down) and repeat the previous step. Then
retry the reader.
If it is still malfunctioning, examine the card guides for any type of debris (pieces of card labels,
dirt deposits, etc.) that may be interfering with the normal operation of the reader. Be sure to
examine the guides over the entire length that the card travels. Removal of the external face of
the mag reader allows a more thorough examination. Removal of all foreign matter usually
returns the mag reader to normal operation. Reassemble and retry the mag reader.
Remove Old Mag Reader
1. Unlock and open the rear door on the head of the Series 1000.
2. Turn off the AC power switch located on the right side of the unit.
3. Remove the hood of the unit.
4. Working inside the head of the unit, remove the four screws that secure the external cover
assembly (shields the mag card reader) to the face of the unit. Save these screws and the
cover; you will reinstall them after replacing the mag reader.
5. Locate the J5 connector in the middle of the left edge of the Series 1000 MPU PCB.
Disconnect the attached cable.
6. Working inside the head of the unit, remove and set aside the two screws, one on each side,
that secure the mag reader to the face of the unit.
7. Remove the mag card reader with cable and rubber gasket from the front of the unit.
Install Mag Reader
8. Holding the mag reader so that the larger square protruding card guide is on the left and the
smaller guide is on the right, install the new rubber gasket and insert the unit into the cabinet
face.
9. Insert the two screws used to secure the reader and tighten.
10. Connect the cable from the mag reader to the Series 1000. Check the rear of the mag
reader for your model number and select the proper procedure below to install the cable.
For Model 100, Rev. L, install the mag reader with the black wire to the left (as viewed from
behind the reader). If the black wire is to the right the cable is reversed and must be
corrected to avoid incorrect data transfer.
