Figure 6-10 The Thermal Test - Tektronix Phaser 380 Service Manual

The Thermal Tests let you select, start and observe the operation of the printers
heaters and determine if they are operational. The test displays the real-time
temperature of active heaters. A simple graphic of a vertical bar"|" between
two brackets [.....|.......] show that the temperature is within its expected range.
If the symbol "|" is replaced by a "<" or ">" outside the bracket, the
temperature is too cold or too hot. Note that the temperature of the
cap/wipe/purge unit's heater is estimated, there is no direct temperature
sensing.
