Troubleshooting
6.7.3 WHEN FLUORESCENT/ LED LAMPS FLICKER (ONLY FOR
100V MODELS)
Problem
Under the usage environment of this machine, at the installation location, fluorescent and/or
LED lamps flicker.
Causes
A voltage drop occurs when an electrical current is applied to the fusing lamp. It depends on
the electrical power environment at the customer's installation location.
Solutions
Set [Flicker Control] to "On".
Four-line LCD panel: SP menu > [Engine Maintenance] > [Flicker Control]
Touch panel: SP menu > [Engine Service Setting] > [Flicker Control]
Side Effect
• The power consumption is increased: When using thinner paper than Thick 1, the fusing
temperature is controlled to increase 5°C (*).
• The face curl of paper may become worse.
*: To control the flicker, the machine slowly raises/drops the fusing temperature when turning
the fusing lamp ON/OFF. The fusing temperature rise becomes slow when printing continuously,
so the fusing efficiency of a solid image in the right or the left edges may become worse. To
maintain the fusing efficiency, the fusing temperature is controlled to increase 5°C.
When the paper in use is thicker than Thick 2, the printing speed becomes half. The fusing
efficiency is not affected even if not
i
ncreasing the fusing temperature.
