PROCESSOR - DRUM Temperature
Adjustment Specification
Purpose: To set the correct temperature for the DRUM.
Setting Temperature: This procedure is required after replacing the PROCESSOR AY,
PROCESSOR DRUM, or the DRE BOARD, or if you expect that DRUM
temperatures are causing image quality problems.
Specification: The temperature at the PROCESSOR DRUM must be between 123.8° -
124.2° C (254.84° - 256.56° F).
Special Tools:
• TEMPERATURE METER with PROBE TL5574
• BLOCK for PROBE, KIT SP7F3477
• LAPTOP COMPUTER with Microsoft INTERNET EXPLORER 5.5

Note:
• A TEMPERATURE METER and PROBE with a BAR TYPE
ELEMENT must be used for this procedure. PROBES with
CIRCULAR TYPE ELEMENTS will not provide correct
readings. The TEMPERATURE METER and PROBE must be
calibrated together at least once per year. If the PROBE breaks, a
new PROBE and the existing METER must be calibrated again.
• The TEMPERATURE METER must be at room temperature
during this procedure. If the METER has been in a hot or cold
vehicle, allow it to adjust to room temperature before using.
