AR-M550/M620/M700 DETAILS OF EACH SECTION 6 - 64
[Toner hopper and toner bottle section]
A. Outline
Adoption of the rotating toner bottle enables large capacity with a com-
pact toner bottle size.
When the remaining toner detection sensor in the toner hopper unit
detects no toner, the toner bottle turns to supply toner to the toner hop-
per. Following supply, since the sensor detects full or empty status
inside the toner hopper based on a standard quantity of approximately
150 g of toner, even if the toner cartridge becomes empty, copying is
not immediately suspended because toner inside the toner hopper is
used (approximately 5K/6% print duty documents).
8 Transfer roller Applies a voltage to transfer toner from the OPC drum to paper.
9 Drum separation pawl Separates paper from the OPC drum mechanically.
10 Cleaning blade
Cleans and scrapes toner from the OPC drum.
11 Resist roller Deflects paper to adjust the paper feed timing to the process section.
12 Paper dust cleaner Remove paper dust from the resist roller to reduce paper dust entry to the process section.
