The depressing cam presses the paper lifting-up plate. When the paper take-up solenoid depressing cam releases to feed the first sheet of paper. The timing to align the leading edge of paper with the image is determined by the paper take-up sensor Both of the sensors are comprised of a photo interrupter and an actuator.

Laser exposure is the process laser beams emitted from the optical unit. The mirror motor (scanner motor) rotates the four-sided mirror counterclockwise to produce a laser light scan. (One side of the mirror produces one scan.)

The SOS (start of scan) sensor detects the laser rays from the SOS mirror and outputs the SOS signals to make the starting position of each line of the image uniform.

2.1.1.8 Fusing

Fusing is the process of fixing the transferred toner image onto the paper. This printer uses the heating roller method for fusing. The heating roller method fixes the toner image with an upper fusing roller that is heated by the heater lamp. The printer uses the cleaning roller to clean that roller if it becomes dirty.

After the power is turned on, the heater lamp lights until the temperature of the upper fusing roller reaches 168°C (334°F). After warm up, the mechanical control board controls the on/off operation

During pause mode, the control temperature is decreased to save power in the standby state, heater lamp (Hi) being turned off.

When the power on/off switch is set to on and the printer is initialized, warming-up starts and the heater lamp is lit. The heater lamp remains lit until the temperature of the fusing section reaches 168 “C (337 “F).

The temperature of fusing section is controlled to keep it at about

135 “C (275 “F). If the standby state persists for 5 consecutive

minutes, the printer enters the low temperature standby mode. When the controller gives the print instruction, the temperature is

controlled to keep the fusing section at about 168‘C (334 “F). The temperature is controlled to keep the fusing section at about 100

Print data and commands transmitted from the host computer via parallel or optional interfaces are read using the interrupt process of the CPU and are stored in the DRAM input buffer.

Data and commands in the input buffer are processed by the CPU, which then stores the printing bit-map data (image data) in the V-RAM (Video RAM) (image buffer) in the DRAM. The size of the V-RAM depends on the available DRAM size and can be specified using printer settings. A page error occurs when the V-RAM is so small that the CPU cannot process data faster than it is transmitted to the engine controller board. printer settings.

6.1 MAINTENANCE

The

method. Unlike most impact or ink-jet printers, the key components in the electrographic process are integrated into an expendable cartridge (the imaging cartridge). replacement of the imaging cartridge is essential to ensure high-quality output. Other maintenance items are also described in this section, which is divided into two sections: user maintenance (preventive maintenance) and service maintenance (repair).

6.1.1

User Maintenance

Users can achieve maximum print quality from the printer by following the procedures below:

6.1.1.1 Cleaning

This section describes the cleaning required for optimal print quality.

●

External Cleaning

Be sure to disconnect the printer from the power outlet before cleaning it. Wipe the cover and external parts of the printer with a damp cloth that has been soaked in a neutral cleaning solution.

. Internal Cleaning

and

Therefore, periodic

printing

Be sure the printer has been disconnected from the power supply and that the fusing unit has cooled down. Clean printer inside using a soft cloth.

6.1.1.2 Consumable Replacement

This printer uses consumable imaging cartridge SO51O2O. The life of this cartridge is 4500 pages

when printing on A4 or

If printed images become faint, remove the cartridge and gently shake it. This will distribute the toner and may make the images darker. If the image is still too light, replace the imaging cartridge. The procedure for changing the imaging cartridge is described below.

●

Imaging Cartridge Replacement

1. Gently open the upper unit and remove the imaging cartridge by pulling it out.

2.

Dispose of the used imaging cartridge.

3. While holding the new imaging cartridge horizontally, gently shake it a few times to distribute the toner evenly.
