Can someone help me change up the words?

A positively charged drum has the image drawn on it with a laser. The areas touched by light become negatively charged.

Positively charged toner particles are attracted to the negative areas on the drum. The drum rolls across paper with a higher negative charge, leaving the toner on the paper.

The paper and toner is then run through a fuser where it is heated to melt the toner to the paper.

How and why do you want to change them?

Certainly! I'd be happy to help you change up the words in the given passage. Here's a modified version:

An electrically charged drum carries an image created by a laser. The regions exposed to the laser become electrically opposite, carrying a negative charge.

Negatively charged toner particles are drawn towards the negatively charged areas on the drum's surface. The drum then moves over paper that possesses an even stronger negative charge, causing the toner to transfer onto the paper.

Next, the paper with the toner is passed through a fuser, where the heat is applied to melt the toner particles, causing them to adhere permanently to the paper.

I hope this revised version meets your requirements! If you have any further requests or need additional assistance, feel free to ask.
