The three iTherm
®
280 indicator lights are:
• Power LED Indicates printer activity and non-recoverable errors
•
Error LED Indicates problems and probability of recovery
•
Paper LED Indicates paper status (paper low)
/ >=."?
The power indicator lets the user know that the printer is ON. If the
POWER
indicator
blinks in conjunction with the
ERROR
indicator, the printer is experiencing a non-
recoverable error: see the fault indicators discussed below. If the
POWER
indicator blinks
and there is no error indicator blinking, the printer is being held in reset by the host.

The
ERROR
indicator lets the user know that the printer is experiencing a problem. If the
POWER
indicator is lit (not blinking), the error is generally recoverable without data loss.
If the
POWER
indicator is blinking, a non-recoverable error has occurred: see the fault
indicators below. If the error is not operator recoverable, a power cycle may correct the
problem. If a power cycle does not correct the fault, the printer must be serviced.

The
PAPER
indicator signals the paper status. If the printer is equipped with a paper low
option, the
PAPER
indicator will blink when the paper is low. The low sensor is adjustable,
and the amount of paper remaining is dependent on the adjustment. If the
PAPER
indicator is lit with the error indicator, the printer is out of paper: in this case, the printer
stops printing and waits for the paper to be changed.
The
ERROR
indicator is the primary fault indicator, and is either always on or blinking if a
fault has occurred. There are three types of faults:
Fully-recoverable faults
Paper out or cover open
Semi-recoverable faults Head jam
Non-recoverable faults
Component failure
