| What is charged in the 2nd step of the printer process? | primary corona (more recently known as the charge roller) |
| In the 3rd stage of the Printer process, how is the writing done? | Laser writes to the drum |
| The 4th stage of the printer process, developing, what does the developing? | Toner is placed on the photo-sensitive drum on areas discharged by the laser |
| What goes on in the transferring phase in the printer process? | tranfers image from the drum to the charged paper by the transfer corona |
| The 2nd to last phase in the printer process is Fusing. What happens in the fusing stage? | heating, pressure and melting done by the fuser assembly |
| What happens during the cleaning phase in the printer process? | Drum is scraped by the wiping blade and preps for the next job |
| What is toner? | charged plastic resin bonded to iron particles ... basically it is ink in a laser printer |
| What does the primary grid do in a printer | It regulates the charge and keeps it uniform on the drum |
| Why are we still using dot matrix (or impact) printers? | We can make carbon copies from them as it actually makes contact with the page |
| How many print heads are there in a dot matrix printer? | 9, 18 or 24 heads, though 18 is not so popular any longer |
| What 2 modes can a dot matrix printer print in? | font mode and dot addressable modes |
| What mode of dot matrix printing has fonts loaded into the printer's memory? | Font mode |
| What mode of dot-matrix printing does its printing dot by dot? | Dot addressable mode |
