Which printer component is most likely failing?
1. Drum
2. Transfer corona wire
3. >>Fuser roller
4. Pickup roller
Explanation : The fuser roller is most likely failing. The fuser roller is the component that uses pressure and heat to bond the toner to the paper. The fuser roller temperature can reach 300 degrees Fahrenheit in some models. If the fuser roller does not reach sufficient temperature or does not provide sufficient pressure, the toner does not bond to the paper and can flake off.
The problem is most likely not the drum. The electrically charged drum is used to transfer toner to the paper. Problems relating to the drum can result in symptoms such as blank print, all-black print, blotchy or spotty print, repeating marks, and so forth.
The problem is most likely not the transfer corona. The transfer corona charges the paper so that toner transfers from the drum to the paper. Problems with the transfer corona most often result in a blank page or poor print quality.
The problem is most likely not the pickup roller. The pickup roller does what its name implies. It picks up the paper from the paper tray to start it on its path through the printer. Problems with the pickup roller usually show up as misfed paper and paper jams.
