tions. For example, printers at cold and low marshy places are maintained at a higher temperature
and vice versa.
Temperature during Warm-Up mode
When the engine executes warm-up mode, the temperature of the fuser is raised to stand-by tem-
perature.
Environmental Index
The engine senses the present environment when it performs a printing job or warm-up procedure
and assigns the fuser with a different temperature for each mode according to the present envi-
ronment conditions. It is very important to control the temperature of the fuser while printing.
Functional Requirements for LSU Control
LSU receives the image data and makes the latent image on the OPC surface using a single
beam.
LSU Ready Check
The WorkCentre 3119 feeding mechanism will pick up paper when the LSU is ready. When the
paper is sensed by the feed sensor, the engine control module checks whether the LSU and
Hsync is ready for an appointed time.
Sequence of LSU module
When the engine control module receives a print command, the LSU performs several steps:
1. Setting up the initial value.
2. With the above result, the LSU controls the polygon motor and laser diode when receiving a
print command.
3. It then monitors the registered value related to LReady and Hsync, and if an error occurs, it
sets up an error flag.
4. If no error flag is raised, it sets the values to mask the video data for horizontal and vertical
regions. However, if there is an error, it will recover according to the recovery sequence.
Functional Requirements of Environment Recognition
This determines the index to indicate the inner environment in a printer. The engine is divided into
several levels according to the index. It is used to control high-voltage values, warm-up timesand
the fuser temperature.
Transfer Roller
There are two cases to recognize the environment for taking the environmental index.
•
Recognizing Environment without paper: Operates when the OPC revolves without the
paper.
•
Recognizing Environment with paper: Operated when the front edge of the paper is
between the transfer roller and OPC.
