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 increasing the fusing temperature.
