Description STROBE is a strobe pulse used to read data from the host computer. The pulse width must be more than 0.5 p.sec. Normally it is HIGH, and data is latched at the trailing edge of this signal. DATA 1 to 8 are parallel data bits. When the signal is HIGH, the data bit is 1, and when it is LOW, the data bit is O. The most significant bit (MSB) is DATA8. The signal state must be maintained for 0.5 @cc. on either side of the STROBE signal active edge. ACKNLG is an acknowledge pulse with an approximate width of 1 or 10P. This signal goes LOW when the data reception is completed, which indicates that the printer can accept new data. Timing with the BUSY signal is speci%d through SelecType. The BUSY signal informs the host computer of the printer state. When the signal is HIGH, the printer cannot accept data, The PE signal indicates paper empty for the standard tray selected through SelecTyps or command, or for the optional paper cassette. Paper empty is indicated by HIGH. Use in reverse mode. Not used. Not used. Logic ground level. Connected to the printer chassis. The printer chassis GND and the signal GND are connected to each other. Not connected. Ground level for the twisted pair return signal. The STROBE signal is ignored when this signal is LOW. This level goes LOW when the printer is: . out of paper . in paper jam state . in enor state q off line Same as for pins19 to 30. Not used. Pulled up to +5V through 1.0 KQ resistance.

1.4.6 Resolution Improvement Technology
The
EPL-3000/ActionLaser 1300 printers have RITech (Resolution Improvement Technology), which is designed to improve print quality at 300 dpi. With this method, the dot-map data extracted from the image data is reassembled to improve the print data.
The main improvement from this technique is in eliminating "jaggies" in diagonal lines. It is most effective when the dot-map data fits the development characteristics of the printer mechanism. It is therefore necessary to set appropriate values in PJL commands.

Note:
RITech is not effective for printing a screen pattern or gray scale. In such cases, RITech must be set to OFF. (The default setting is MEDIUM.) Since the RITech effect depends on the toner condition, it should be adjusted when the imaging cartridge is replaced or after the imaging cartridge is used for a long time.
The following settings are available in PJL commands for RITech: DARK, MEDIUM, LIGHT, and OFF. When the toner density of area A is almost the same as that of area B (as shown in the figure below), the RITech setting is optimum. In other words, the optimum setting is achieved when it is difficult to distinguish the shape of area A from that of area B.

Operating Principles
2.1.1.1 Paper Feeding
On the multi-purpose tray (standard tray), various sizes of paper can be fed by fitting the paper guide against the sides of the paper. The depressing cam is fixed to the shaft of the paper take-up roller, but the transport rollers are free. The transport rolls are rotated by the rotation of the transport roller. The depressing cam presses the paper lifting-up plate. When the paper take-up solenoid (SL1) is actuated, the paper take-up roller rotates and the 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 (PC1). Both of the sensors are comprised of a photo interrupter and an actuator. When the paper turns the actuator on, output from the paper take-up sensor (PC1) switches to "L" and output from the paper exit sensor (PC2) switches to "H".

Operating Principles
Drum charge is the process of charging the PC drum with static electricity before laser exposure. This printer uses the brush charge method, rather than corona charge, to charge the drum. In brush charge, there is no generation of ozone as a result of corona discharge. This method also allows the drum to be charged at a low voltage, because a direct electric load is applied to the PC drum.

2.1.1.4 Laser Exposure
Laser exposure is the process of creating an invisible static electric image on the PC drum with 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.

2.1.1.5 Development
Development is the process of creating a toner image on the PC drum by applying toner to the invisible static electric image. The doctor blade spreads a thin, even mat of toner over the flexible sleeve. When the toner passes between the doctor blade and the flexible sleeve, it becomes negatively charged. The flexible sleeve transports toner to the surface of the PC drum and controls the development with the developing bias voltage. No positive toner is transported, and the dwtor blade is charged to prevent the printing from having a foggy background.

After the image is transferred onto paper, any remaining toner on the PC drum is scraped off by the cleaning blade and collected in the used toner bottle.
2.1.1.7 Image Transfer
Image transfer is the process of transferring to the paper the toner image created on the PC drum during development. ?his printer uses the roller image transfer method, instead of corona image transfer, as the image transfer process. In roller image transfer, there is no generation of ozone as there is with corona discharge. Also, there is no blurring caused by motion in the image transkr, because the image transfer roller pressure bonds the paper vvith the PC drum A reverse bias voltage is applied so that the positive toner is not transkwred onto the image transfer roller. (The drum charge bias voltage is used.)

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 of the heater lamp, based on the TH1 ;ignals from the thermistor.
