:
. This condition results when the printer is in an over temperature condition. If the
printer is operating in an environment where the ambient temperature is roughly room temperature, this
error would most likely be the result of a hardware problem. The printer will automatically resume
operation after the detected head temperature reaches legal operation limits.

RROR
:
If the printer detects a power supply voltage (+24VDC to +25VDC) outside of legal
limits, then a voltage error occurs. This error could be the result of a poor cable connection. The printer
will automatically resume operation after the power supply is detected within legal limits.

RROR
:
This type of error occurs when the printer senses an internal error due to
connectivity or interfacing problem with the thermal print head. This can be a result of a cable problem
between the main controller board and the printer engine. The printer will remain in this error state until
the power is cycled or the unit is reset. If the problem persists, the printer will require service.

:
If the paper type selected is indexed paper, and while feeding paper or
printing a black mark is not seen within approximately 10” of paper, then this type of error will occur. The
purpose of this error is to alert the user to the presence of the wrong kind of paper in the printer, or that
the paper was inserted in the wrong direction (so the black mark index is rotated 180 degrees. The
condition is cleared by raising of the head release lever (presumably to change the paper).

:
This error indicates that the printer detected an error in the paper path for presenting the
ticket to the customer. To clear this condition, open the printer head and inspect for a jammed ticket.
2.6 Paper Feed Operation
The printer has been designed to run with black mark indexed paper. Paper feeding is accomplished by
use of the feed button. Each long press (~1 second) of the feed key will result in paper being advanced to
the top of the next form.
2.7 Cut Key Functions
The CUT key performs no function in the PSA-66-ST printer and should be ignored.
2.8 Self Test
If the FEED key is held depressed during power up or reset, a self test will be triggered which will result in
the proper printing of a configuration ticket if the test passes successfully. The test ticket is illustrated in
Figure
2-2
and it contains important information about how the unit is configured.
