Dual Density Values
Dual density calibration values are stored in the EEPROM of the Microprocessor. It is not necessary to
recalibrate the optical density values unless:
- The Microprocessor Board or microprocessor has been replaced.
- Major service or repair replacement has been performed on the dual density sensor or emitter.
- Testing on the bench in diagnostics mode indicates a high rate of “C0” errors related to the
“Density Sum”. The “C0” error will have a message indicating “Dual Density Sum Over Limit”.
If the “C0” error is not associated with a “Density Sum Over Limit” error, Density Calibration will
not correct the problem.
System Stalls and Incomplete Power-up
For the calibration process to work properly, the System must be powered up without any notes or obstructions in
the note path.
- If any object is present in the note path during calibration, the process will not complete properly, resulting
in such problems as erratic performance or poor acceptance.
- If an obstruction is present in the note path during subsequent power-ups, the acceptor will try to clear the
note path and complete the power-up sequence. If the acceptor cannot clear the note path, the power-up
sequence will be halted, and the stacker punch will not cycle.
- If the System has been improperly powered up and stalls, power down the System, and check the note path.
Correct the problem as necessary and re-energize the System.
Dip Switch Note Inhibits And String Sensor
The DIPswitches on the microprocessor board are read during power-up to check the communications mode,
whether any notes have been inhibited and whether the string sensor is enabled or disabled. The EPROM / FLASH
on the acceptor Microprocessor Board must support the protocol selected or the System will not operate properly.
The DIPswitches are located on the Microprocessor Board. Table 1-1 lists the switch functions.
