Quality Bulletin: Reflexite Platen Lifting
Dear Valued Partner:
We recently concluded an investigation of reported issues regarding the reflexite platen on our HandReaders.
Excessive mold release was left on a vendor’s plastic chassis assemblies. Those chassis became resistive to
the adhesive glue of the reflexite platen and overtime, the reflexite platen starts lifting and peeling off.
F series hand readers manufactured with a serial number ranging from 1193000 – 1196000, and build date
September 1st - October 30th. We believe that a small percentage of those shipments could be affected (700 –
850 units), however, at this time there is not enough data to bound the serial number or manufacturing date
any closer than this.
If you have identified one of the affected HandReaders above, please contact our Technical Services
department at (866) 861-2480. Our Technical Services representatives will issue a Return for Credit
Authorization number for the defective platen(s). Please be prepared to provide a purchase order for a
replacement platen(s), using the part number S-PL-F30. A same-day sales order will be placed and new
platen(s) will ship out to you overnight.
Please use our UPS account number that was given to you to return the defective platen(s) to the factory.
Once the returned platen is received, a credit memo will be issued to you to offset the purchase order for your
replacement components.
We are also screening all HandReaders that we receive for in-house repairs. If the aforementioned issue is
identified, the platen will be replaced at no cost.
Corrective quality and inspection actions have already been put into place with our vendor. We apologize for
the inconvenience this issue may have caused you and your customer and appreciate your loyalty as we
strive toward its resolution.
Sincerely,
Bonnie Hunter

How To Replace the Platen Base
PLEASE READ BEFORE PROCEEDINGCare must be taken in changing the platen-base because the
“Calibration Values” of the HandReader can be affected. To ease in the
down time of your Customer, this technical note will help guide you in
the changing of the platen-bases.
It is highly recommended that before proceeding, to take note of the
HandReader’s existing “Calibration Numbers”. The calibration numbers
should be within this recommended range R= 0 (+/-2) C= 0 (+/-2) E=100
(+/-20) for optimal verification performance. If the numbers are outside of
this range please clean and “recalibrate” the HandReader(s) before
proceeding. If the R and the C remain out side of this range it is
recommended that the HandReader(s) come back to RSI for cleaning.
Once the platen-base has been replaced there may be a change in the E
(exposure) number, this might be due to, cleaning agents that have
dulled the older platen’s surface, vandalism, or debris.
Since this procedure does involve the camera assembly please take
great care in the handling of it.
PROCEDURE
1. Check and write down Calibration values.
2. Insert key and turn key away from wall to unlock the reader. When latch releases
guide Reader to open position.
CAUTION: If the Reader is equipped with an optional battery backup,
remove the J7 jumper before proceeding. Failure to do so could lead to a
risk of shock and/or main board damage.
3. Disconnect the power supply from the power source.
4. Tag and remove all external connections to aid in re-attachment.
5. Remove Reader from wall by sliding Reader to the right until sleeves clear the pins.

How To Replace the Platen Base
CAUTION: Before removing the back plate of Reader, wear a grounding
wrist strap to help aid in protecting the circuit board from any ESD
damage that might occur from improper handling.
6. Set the Reader on a firm surface such as a table. Remove the four screws that
secure the back plate to the Reader. See figure 1 below.
Figure 1
CAUTION: DO NOT allow the ground lug to contact any part of the main
circuit board. If a Backup battery is installed, please tape ground lug. If
the ground lug touches the main board with a Backup Battery installed,
it will short the main board.

7. Carefully remove the back plate.
8. Locate the cable that on the left side of the HandReader that runs from the top panel
circuit board to the main circuit board. Disconnect this cable from J9 on the main
circuit board. See figure 2. To remove the (J9) connector on the main circuit board,
depress the retaining clip on the connector and pull upwards. Take care to pull on
the connector and to not pull on the cable.

10. Carefully slide out the main circuit board about 1” until the ribbon cable between the
camera assembly and J2 on the main circuit board can be detached from J2. Gently
pull up on the connector, being careful to not disturb the camera assembly. See
figure 2
11. To remove the (J5) connector on the main circuit board, depress the retaining clip on
the connector and pull upwards. Take care to pull on the connector and to not
pull on the wires. See figure 2
12. Carefully remove the main circuit board by sliding it free from the chassis.
13. Remove the 3 platen mounting screws and set aside taking note as to which type of
screw goes where. See figure 3
Figure 3
14. Turn HandReader over and grasp chassis as shown in Figure 4 and pull apart.

CAUTION: DO NOT force apart the HandReader; it may take the camera
out of alignment. There may be a build up of debris between platen and
chassis, so use care when separating the two.
15. Clean any debris from the front part of the HandReader, in order to create a good
seal with the new platen-base.
16. Line up and slide new platen onto chassis. Do not force. If properly lined up it will
slide into place with ease.
17. Make sure that the guide pins are seated properly in the camera housing. The guide
pins should be level with the camera housing assembly. See figure 5 below for an
example of improper placement and 6 below for the correct placement.

18. Replace the screws in the order listed on figure 7. Be careful to not over-tighten
while at the same time still making sure that the screws are snug and that the platenbase is seated flat against the chassis.

19. Carefully slide the main circuit board back into the chassis using the circuit board
guides to seat the main circuit board correctly. See figure 8. Leaving the main circuit
board out about 1”. Attach the camera cable to J2 and J5 on the main circuit board.
Take care to align the connector to the pins on the main circuit board and do not
twist the flat rainbow colored cable, as this will damage the camera.

20. Locate the cable that runs from the top panel circuit board to the main circuit board.
Connect this cable to J9 on the main circuit board. See figure 2 for cable routing.
Make sure that the cable is seated below the back plate standoffs or else the cable
will get pinched when the back plate is re-installed.
21. Slide the main circuit board in the rest of the way. Make sure that the board is
seated properly and does not stick out further than the standoffs for the back plate.
22. Place the back plate onto the chassis. Making sure that the back plate is seated flat
and taking care to not pinch the ground strap.
23. Reattach the ground strap from the main circuit board to the lower left back plate
screw. Do not over tighten. Replace the 3 remaining screws. Do not over tighten.
24. Realign the sleeves of the back plate to the pins of the wall mount and slide the
Reader to the left.
25. Reconnect the J7 battery jumper if back up battery is installed.
26. Reconnect all external connections.
27. Rotate Reader up and turn key away from wall to release lock. Press Reader against
the wall and turn the key towards the wall.
28. Check calibration numbers. If ok…
29. Replacement is complete.
