|
What is Paper Transport Assembly? |
Moves the paper through the printer. |
|
What is Transfer Corona? |
Applies a positive charge to the paper. |
|
What is high voltage power supply? |
Delivers high volts needed to make the printing process happen. Converts household current into high DC voltages used to energize the primary and transfer corona wires. |
|
DC Power supply? |
delivers the lower volts needs to other parts of printer aside from corona. |
|
What is fusing assembly? |
