2.2 Paper Installation

2.2.1 Paper Loading

POS892 adopts 79.5mm±0.5mm width thermal paper roll. Steps of Loading Thermal Paper are as below:

1. Hold down the upper cover button on the left side, open the movable upper cover.
2. Draw a certain length of the paper roll, put the paper end on the print head.
3. Close the upper cover and press it downwards lightly.

2.2.2 Solution to Paper Jam

If the cutter jams, turn off the power, and turn on again; the cutter will return to its original position. If paper jams, open the paper storage cover and take out the paper. If the cutter cannot return to the original position, open its cover and manually turn the white plastic gear in the suggested direction to return the cutter to its original position.

If the cutter jams but you wish to avoid data loss, do not turn off the power. Manually return the cutter to its original position as described above. Then, open the paper cover, remove the paper, and close the paper cover. The printer will automatically recover from a Cutting Error.

2.3 Interface

2.3.1 Serial Interface

The serial interface of SP-POS892 printer is compatible with RS-232C, supports DTR/DSR and XON/XOFF handshaking protocols, and uses a DB9 socket (female). The pin order of the serial port is shown in Figure 2-2.

Figure 2-2 shows a DB9 connector with pins numbered 1-9. The diagram indicates pin numbers and their corresponding signal names.

2.3.2 Ethernet Interface

Models with an Ethernet interface use an RJ45 Network socket. The appearance is shown in Figure 2-3.

Figure 2-3 shows an RJ45 Ethernet connector.

2.3.3 USB Interface

The standard accessories of POS892 printer include a Mini USB cable with a D Type connector, which connects the printer and the main device. The USB type is a slave device type (DEVICE). Pins description of Mini-USB is shown in Figure 2-4.

Figure 2-4 shows a Mini-USB connector with pins labeled 1 to 4. The table lists Pin, Function, and Notes: 1: V Bus (Power +5V), 2: Data- (Data-), 3: Data+ (Data+), 4: GND (Ground).

2.3.4 Cash Drawer Interface

The cash drawer interface of POS892 adopts an RJ-11 6-pin socket, as shown in Figure 2-5.

Figure 2-5 shows an RJ-11 6-pin connector.

The pin assignment is as follows:

2.3.5 Power Connection

POS892 uses an external power supply adapter (24V±10%, 1.5A). The power socket is model A-1009-3P, as shown in Figure 2-6.

Figure 2-6 shows a power socket with pins labeled 1, 2, 3. The pin assignment is as follows:

2.4 Buzzer, Buttons and Indicators

The POS892 printer has one button (FEED), one inner buzzer, and three indicators.

The FEED button is for paper feeding. Its function (enabling/disabling on/off) can be set by print command. When enabled, pressing the FEED button starts paper feeding; releasing it stops feeding.

The buzzer indicates the error status type, which can be set to enable or disable error alarms via parameter settings. The buzzer's indication is consistent with the error indicator.

The green POWER indicator shows the power status; it lights up when the printer is turned on.

The red indicator is the paper status indicator; it lights up when the printer is out of paper.

The Red/Blue indicator is the ERROR/ALARM indicator. The red indicator is dark when the printer works normally. It flashes during abnormal alarm status. If it stays on for a long time, it indicates the paper case is open during printing. The blue indicator flashes to signal that the printer has received a document.

When the document received indicator flashes, the buzzer rings three times, indicating the printer has received a document.

When the error indicator flashes and the buzzer rings, it signifies an error in the printer.

Different flicker types indicate different error types:

• 1. Non-recoverable error: The number of indicator flickers and buzzer sounds indicates the error type, followed by persistent lighting.
• 2. Recoverable error: The number of indicator flickers and buzzer sounds indicates the error type, followed by persistent indicator-off.
• 3. Auto-recoverable error: The indicator flickers and the buzzer sounds persistently.
• 4. Paper out: The PAPER OUT indicator lights up and the buzzer sounds persistently. If the paper case cover is open, the system tests for paper presence rather than paper out status.

The details for Non-recoverable errors are as follows:

Recoverable error details:

Auto-recoverable error details:

2.5 Power on status

Ensure the paper cover is closed when the printer is powered off. Press the power button. The error indicator and paper out indicator will flash twice alternately and then turn off, indicating the printer is in normal working mode.

2.6 Self-test

The self-test checks the printer's condition. If the printer prints the self-test receipt correctly, it means the printer is working normally, except for the interface with the host. Otherwise, it requires repair.

The self-test prints the manufacturer name, printer type, software version, interface type, printer default parameters, 96 ASCII characters, default code page content (English or Chinese), and barcode type.

Way of self-test: Hold down the 【FEED】 button and turn on the power. The self-test begins automatically. Different models may have slightly different self-test parameters. The self-test for the SP-POS892US model is shown in Figure 2-7.

Figure 2-7 shows a sample self-test receipt containing details like Manufacturer (SPRT), Model (POS891/892), Version, Interface (RS232, USB), Baud Rate, Data Bits, Parity, Handshake, Language (Chinese), Font, Print Width, Print Density, Print Speed, Barcode Types (UPCA, etc.), and 2D Code Types (PDF417, QR CODE, DATA Matrix).

2.7 Hexadecimal Printing

Turn on the printer according to the steps below to enter Hexadecimal Printing mode:

1. Open the cover.
2. Hold down the 【FEED】 button, connect the power, wait for the alarm, and close the paper cover.
3. The printer will print 3 lines as below:

Hexadecimal Dump

To terminate hexadecimal dump, press FEED button three times.

This mode prints all input as hexadecimal numbers. Feed one line with a single click of the “FEED” button. After 3 clicks, it will print "*** Completed ***" and exit hexadecimal printing mode.

2.8 Parameter Setting

There are two ways to set printer parameters:

1. Use the setting tool on the PC side.
2. Set using the buttons. The specific operation is as follows:

When the printer is powered off, open the paper case cover. Hold the 【FEED】 button, then switch on the printer and release the 【FEED】 button when the status indicator and paper-out indicator flash alternately. Then press the 【FEED】 button twice and close the paper cover. The printer enters the setting mode and prints the first parameter and its default value. Detailed methods can be found in Appendix A.

Steps for exiting parameter setup: Open the paper case cover and press the 【FEED】 button; then close the paper case cover and release the 【FEED】 button. The printer will save the parameters, exit setting mode, and enter normal working mode. Data will not be saved if the printer is turned off directly.

2.9 Enter the program upgrade mode

When the printer is powered off, open the paper case cover. Hold the 【FEED】 button, then switch on the printer and release the 【FEED】 button when the status indicator and paper-out indicator flash alternately. Then press the 【FEED】 button five times (RS232 and USB interfaces support this; Ethernet uses a web page mode for direct upgrade). Close the paper cover; the printer enters program upgrade mode. At this time, the status indicator flashes once per second.

Quick enter method: Open the paper case cover when the printer is powered off. Hold the 【FEED】 button and switch on the printer, then release the 【FEED】 button quickly. The printer enters program upgrade mode, and the status indicator flashes once per second.

Notice:

• 1. When the printer enters program upgrade mode, the paper-out indicator flashing means the interface cannot be upgraded.
