Removing and Replacing the Printer Interface Board
To remove the printer interface board (4), proceed as follows (see Figure 2):
1. Disconnect the printer driver ribbon cable (5) and printer interface ribbon cable (6).
2. Remove the four screws (7) from the printer interface board. Retain the screws.
3. Remove and retain the printer interface board and the printer interface board shield (8).
To replace the printer interface board, proceed as follows (see Figure 2):
1. Connect the printer interface ribbon cable (6) to printer interface board header P1. Cable
assemblies may differ. If the connector is not polarized, note the orientation of Pin 1 of the
connector and Pin 1 of the board.
2. Connect the printer ribbon cable (5) connector to printer interface board header P2.
3. Place the printer interface board (4), component side down, on the module. Replace the printer
interface board shield (8) and insert the four screws (7) retained during disassembly.
4. If the printer interface board has been repaired, or if a new printer interface board has been
installed, the print quality may require adjustment. See ‘Adjusting Print Quality’ below.
Removing and Replacing the Battery
You may encounter printers that were manufactured with replaceable batteries or printers
manufactured with soldered batteries. Replaceable batteries must be properly stored and handled
to avoid discharge. The time and date functions of the printer are battery supported when the unit
is not running. If the time or date printout is incorrect, try resetting the time and date as described
in the Operator’s Manual. Power the printer and STATIM OFF and wait several minutes before
powering them back ON. If the time and date are still incorrect, replace the battery on the printer
interface board.
To replace the battery, proceed as follows:
1. Remove the Printer Interface Board as described in
Removing the Printer Interface Board
.
2.
a. If there is a replaceable battery, remove and discard the old battery. Install a new battery.
Always replace the battery with a fresh battery of equal rating and size.
b. If the battery is soldered, carefully de-solder BAT1 from the component side of the board.
Note the orientation of the anode and cathode. Solder the replacement battery in position
BAT1.
Adjusting Print Quality
To adjust print quality, use the R21 contrast adjustment pot (9) located on the Printer Interface
Board.
To adjust the print quality, proceed as follows (see Figure 2):
1. Remove the cover.
2. The printer contrast adjustment pot (R21) is located at the edge of the board. Adjustments
may be made using a small adjustment tool while the printer module is still in the cover
assembly.
