Functional Requirements of Toner Cartridge
Installation Toner Cartridge
The WorkCentre 3119 main firmware checks the validity and status of the CRUM on the toner car-
tridge. The crum stores the ID, the opc cycle, the toner consumption and so on.
Toner Save
This function is to reduce toner consumption. There are 3 different methods used on this printer
to do so:
• Modulating the video data
• Modulating the DEV voltage in the engine firmware.
• Controlling the power of the laser diode.
Functional Requirements of OPC Drum
Clean OPC Drum
To clean the contamination of the OPC drum, all remaining toner should be removed.
Manual: This function can be used by the user at anytime. When the user selects this function, the
engine receives the OPC cleaning command from the main system and performs the cleaning op-
eration. There are two methods to clean the OPC. One is the minus clean mode, and the other is
the plus clean mode.
Minus clean mode: Supplying negative voltage to the transfer roller to remove toner with a nega-
tive charge.
Plus clean mode: Supplying positive voltage to the transfer roller to remove toner with a positive
charge. The developer team presents the cleaning process.
Functional Requirements of Fan Operation
The fan is always in operation except during sleep mode. When the engine encounters an error,
the engine stops the fan. However, when the engine enters sleep mode, the engine stops the fan
after 5 minutes due to toner fusing. The Fan operates during warm up and print.

Door Open

When the cover is open, the engine stops all functions. It sends an error message to the main sys-
tem and an error message is displayed on the LCD. If the cover is closed, the engine operates the
warm-up process.
No paper
When the paper cassette is empty, the engine notifes the printer system. Then, an error message
is displayed on the LCD. When the user loads paper in the cassette, the error is removed.
