In this article, we will consider another artifact that occurs during printing due to damage to the fuser unit (thermal film) of the printer.
On the left edge of the sheet, the image is smeared or not visible at all. If you run your finger along this flat, you will notice that the toner is loose on the paper and is easily erased. This is a clear sign of damage to the printer fuser. The thermal film has torn.
If the printer continues to be used without solving the problem, the swath will become wider. Then the rubber shaft will be damaged. And printer repair will be more expensive.
This is a damaged thermal film. Often the use of paper with the remains of clips or staples from a stapler leads to its destruction.
