Product spec and feature
11) SMPS (Switching Mode Power Supply)
This power supply uses the AC supply voltage to generate the DC voltages used by the system.
The SMPS has 5 output channels (+3.3V, +5V, +24V).
12) HVPS (High Voltage Power Supply)
The HVPS creates the high voltages (Transfer, Charge, Attr, Supply DC, Supply AC) used for the
electro photographic process. The high voltage is created from the 24V line from the SMPS. High
Voltage output is supplied to the toner cartridge, PTB unit.
13) Main Controller PBA
The Main controller PBA is very important as it is the heart of printer. It has several major function
blocks.
* CPU : This manages the printing order from the host, creates bitmap data for the
engine to print and controls various devices that are needed to operate the printer.
*Engine Control Block: This manages images and controls various kinds of I/O
* Memory Block : The operating system uses this to store video data and printing orders given by host.
* ROM Block : The printer OS and PDL Interpreter are stored here.
* In addition there are USB 2.0 Block, IEEE 1284 Block, Option Block, OPE Panel, etc.
14) Drive PBA
Each toner cartridge requires the HV Supply only when that colour image is being processed. This
unit takes its HV source from the HVPS and using 4 solenoids selects which cartridge is to receive
the Supply voltage. This section also contains the DEVE motor, DEVE clutch, and DEVE solenoid
drives. These are activated in sequence as required by the printing process.
15) DEVE CRUM PBA
This detects new or used toner cartridges and also checks that cartridges are approved parts. If a
toner cartridge is not suitable for the machine an error message is displayed.
