the LED array, which uses light emitting diodes to produce its images. The latent image retains
much of the charge applied to the drum's surface during charging. The segments of the
photoreceptor drum that correspond to the non-image areas have a reduced electrical change.
Step 3: Developing
In the development cycle, charged toner is attracted to the latent image by static electricity,
making the image visible.
Step 4: Transfer
The paper is brought into contact with each of the four photoreceptor drums, one after the other,
transferring the toner images to the paper. The transfer process applies a charge through the
paper so the toner particles adhere to the paper rather than to the drum.
Step 5: Fusing
Heat and pressure fuses the toner to the paper to produce the final product.
