Platten bearings
Carriage rails
Printhead
Paper advance bearings E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: C. Printhead
The printhead is the component in a dot-matrix printer that prints the text or images on the paper. It is made up of a number of small pins that strike the ink ribbon, which then transfers the ink to the paper. The printhead is a very delicate component and should never be lubricated, as this could damage it.
The other options are all components that should be lubricated on a regular basis.
- Platten bearings: These are the bearings that support the printhead carriage. They should be lubricated with a light oil or grease to reduce friction and keep them moving smoothly.
- Carriage rails: These are the rails that the printhead carriage rides on. They should also be lubricated with a light oil or grease to reduce friction and keep them moving smoothly.
- Paper advance bearings: These are the bearings that support the paper as it is fed into the printer. They should be lubricated with a light oil or grease to reduce friction and keep them moving smoothly.
It is important to follow the manufacturer’s instructions when lubricating any components on a dot-matrix printer. Using the wrong type of lubricant or applying too much lubricant can damage the printer.
