1.7 Various Sensors and Switches 1. Feed Gap Sensor

The feed gap sensor detects the label/ticket gap to locate the position. The sensor is set to detect gaps along the center line of the label/ticket roll width across the length of the media.

In case of Label

7

2. Black Mark Sensor The black mark sensor locates the position of the ticket by emitting infrared rays onto the black mark at the back side of the ticket. The sensor is positioned central to the ticket roll width on the mechanism.

In case of Ticket

3. Ribbon End Sensor The sensor detects the end portion of the ribbon. 4. Ribbon Encoder Sensor The encoder is located in the gear box of the DC motor and is used to detect

whether the ribbon is broken or abnormally rewound. 5. Label End Sensor The sensor detects the end portion of the label. 6. Thermal Head Position Switch The switch detects whether the thermal head is set in a printable status or not. 7. Peel-Off Sensor The sensor detects the backing paper of the label.

Note: (1) The max. paper length above is for standard 2MB memory. (2) The printing length above is based on the assumption that there is not any

downloaded file in the printer memory. (3) The quoted width and thickness are said of the label plus the backing paper. (4) Likewise, the approval of a label entails that of its backing paper. (5) In the peel off mode, the minimum pitch is 35 mm. (6) In the cutter mode, it is recommended that the print media be wound outside lest

paper jam should result. (7) In the cutter mode, the paper thickness must be less than or equal to 250 m. (8) Paper shape is as shown on next page:

3.10 Stepping Motor and DC Motor Driving / Protection Circuit

Figure 13 Stepping Motor and DC Motor Driving / Protection Circuit

Above is Stepping Motor and DC Motor Driving / Protection Circuit. JP12 connector sends patterns as shown in Table 1. The power level of the stepping motor is determined by the status of I0 and I1. Power level is as shown by the patterns in Table 2. Motor port is protection pin. When it is in LOW status, power of motor system will be disconnected. Power reverts to "ON" when the pulse of MOTOR pin is in "HIGH" status. PHASE1 and PHASE2 determine the stepping motor driving circuit mode. For example: in full step mode, the sequence of PHASE1/PHASE2 is 0/0 0/1 1/1 1/0.

3.11 Communication (Serial and Parallel Port) Circuit

Figure 14 Parallel Port and RS-232 (Serial Port) Circuit

RS-232 circuit is used with externally connected PC or keyboard. JP13 is connected to PC serial port through RS-232 connection. RxD is data receive pin of MCU. CTS is Clear To Send of MCU, the signals of which are sent through external device. TxD is data output pin of MCU. RTS is Request To Send signal which MCU sends to external device. Parallel port is is connected to the parallel port of the externally connected PC through the centronics cable. When PC strobe signals enter, the printer responds 'busy' status until parallel port data is read. When it is in 'error' status, the printer responds error signals to PC.

3.12 Cutter Driving Circuit

Figure 15 Cutter Driving Circuit

Above shows the cutter driving circuit. When printer power is turned on, RESET signal is 1. CUTTER OUT controls the activation of the cutter. CD_PHASE conrols the rotation direction (HIGH, forward; LOW, backward). When the signal of CUTTER OUT is LOW, cutter will be activated. Cutter sensor sends Hi-Lo signals to MCU through CUTTER SEN. Pin that detects the cutter action. CUTTER SEN : Detect pin of cutter sensor (check if cutter position is correct, usually in HIGH status). PEEL-OFF SEN : Detect pin of peel-off sensor (usually in high status). .

5.1 Error Messages 1. Syntax Error The command format is incorrect. The serial port setting is incorrect. 2. Out of Range Numeric input is too large to be processed. The input string is too long to be stored. The size of the text or bar code exceeds that of the label. 3. Download Error The download file format is incorrect. There is not enough memory to store the file. 4. Stack Overflow A mathematical expression is too complicated. Divide it into several expressions. The nested routine is too deep. 5. Memory Error Too many variables defined. 6. RS-232 Error The serial port setting is incorrect. 7. File not Found Cannot open the file specified. Download the file again. 8. Type Mismatch Variable type mismatch. 9. Gap not Found Cannot detect label gap. Calibrate the label again. 10 Clock Access Error Can not read from / write to the real time clock.

5.2 Troubleshooting

The following guide lists some of the most common problems that may be encountered when operating the bar code printer. If the printer still does not function after all suggested solutions have been invoked, please contact the Customer Service Department of your purchased reseller or distributor for assistance

Problem Solution

Ribbon does not advance or rewind Check the setting of print method. (SET RIBBON ON)

Poor print quality Clean the thermal print head. Adjust the print density setting. Ribbon and media are not compatible.

Power indicator does not illuminate

Check the power cord, see whether it is properly connected.

ON-LINE indicator is off Out of paper or out of ribbon Calibrate the sensitivity of gap sensor.

ERROR indicator lights on Command syntax is not correct. Rewind ribbon paper core is not installed. Serial port baud rate setting is not correct.

Continuous feeding when printing labels

Calibrate the gap sensor.

Note: When the voltage is too low or when the printing covers a wide range on the label, the

print density may become inadequate. At this, please lower the print speed to secure normal print quality.

56

5.3 Calibrating the Gap Register 1. Install the label. 2. Turn on the printer power while pressing the PAUSE button, the printer will calibrate

the transparency of the backing paper and adjust the gap register.

5.4 Self Test 1. Install the label. 2. Turn on the printer power while pressing the FEED button, the printer will: (1) Print print head check pattern. (2) Calibrate the label length. (3) Print internal settings. (4) Initiate self-test. (5) Enter dump mode.

5.5 Clearing RAM Press the PAUSE button and FEED button more than 3 seconds, the printer will clear the memory and reset the printer. Be sure to calibrate the gap register with blank label before printing.

5.6 Diagnosis Operation Procedure When the power is turned on without pressing any button, self diagnosis is automatically performed to test the available memory. If any error should occur at this moment, the ERR light will flash. Do the self test and inspect the test pattern to check if the thermal head is available.

57

5.7 Cleaning the Print Head The printer should be cleaned at regular intervals to retain high quality and optimum performance. The greater the usage of the printer, the more frequent the cleaning. 1. Turn the power off 2. Open the printer cover. 3. Open the printer carriage by pulling up the release lever on the left side of the front

rubber roller. 4. Remove the ribbon and label. 5. Clean the print had element with a head cleaner pen. 6. Clean the front rubber roller with a piece of alcohol moistened cloth.
