The machine turns on or off the scanning lamp using the drive signal (XE-ON) generated by the CPU on the reader controller PCB. In response to the signal,

the inverter PCB generates high-frequency high voltage in the activation motor circuit using the drive voltage (+24 V) supplied by the reader controller PCB,

thus turning on the scanning lamp.

2. Detecting an Error

The machine identifies an error in the intensity of light as an activation error occurring when the lamp is initially turned on (shading correction).

ERROR CODE:

E225

-0001: at time of shading, the detected intensity of light falls short of a specific level.

-0002: in ADF mode, the intensity of light between originals falls short of a specific level.

iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N

The machine's scanning lamp is a xenon lamp consisting of a tube in which xenon gas is sealed. On the inner side of the glass tube are 2 electrodes running parallel

to the tube axis, while the inner side is coated with fluorescent material. When high-frequency high voltage is applied to the electrodes, the gas inside the tube starts

to discharge, thus illuminating the fluorescent material.

increases the speed at which the original is moved.

e.g., at 50%, collects the image at twice the speed for 100%.

325 mm/sec

decreases the speed at which the original is moved.

e.g., at 200%, collects image data at 1/2 the speed for 100%.
