1. PRODUCT INTRODUCTION

Thank you very much for purchasing Kroy K4350/4350C printer. The attractive desktop printer delivers superior performance at an economical price. Both powerful and easy-to-use, K4350/4350C printer is your best choice among desktop direct thermal and thermal transfer label printers.

K4350/4350C printer offers both thermal transfer and direct thermal printing at selectable speeds of 1.5 and 2.0 inches per second. It can accept a wide range of media, including roll feed, die-cut, and fan-fold labels or tags for both thermal transfer and direct thermal printing. All of the most frequently used bar code formats are available. Fonts and bar codes can be printed in any one of four directions. K4350/4350C printer provides a choice of five different sizes of alphanumeric fonts. By using font multiplication, an even greater range of sizes is possible. Smooth fonts can be downloaded from provided user friendly label design software. In addition, K4350/4350C is capable of independently executing BASIC programming functions, including arithmetic, logical operation, loop, flow-control and file management, among others. This programming capability provides the greatest efficiency in label printing. The status of printer and error messages may either be printed out or viewed on a monitor by means of the RS-232 connection.

2.5 Buttons and Indicators

PWR. (POWER) Indicator

The green PWR. indicator illuminates when the POWER switch is turned on.

ON-LINE Indicator

The green ON-LINE indicator illuminates when the printer is ready to print. When PAUSE button is pressed, the ON-LINE indicator flashes.

ERR. Indicator (Error/Paper Empty)

The red ERR. indicator illuminates in the event of a printer error, such as memory error, syntax error, and so forth. For a full list of error messages, please refer to section 4.2, Error Messages.

PAUSE Button

The PAUSE button allows the user to stop a print job and then continue the printing with a second depression of the button. By pressing the PAUSE button: (1) the printer stops printing after the printing label, (2) the PAUSE LED flashes, and (3) the printer will hold all data in memory. This allows for trouble-free replacement of label stock and thermal transfer ribbon. A second depression of the PAUSE button will restart the printer.

Note: If the PAUSE button is held down for more than 3 seconds, the printer will be reset and all data of the previous printing job will be lost.

FEED Button

Press the FEED button to feed the label to the beginning of the next label.

To initiate the self test mode, depress the FEED button while turning on the printer power. The printer will calibrate the label length. If the label gap is not detected within 7", the printer stops feeding labels and the media is treated as continuous paper. In self test, a check pattern is used to check the performance of the thermal print head. Following the check pattern, the printer prints internal settings as listed below:

1. Printer model and firmware version
2. Mileage
3. Flash times
4. Check sum
5. Serial port setting
6. Code page setting
7. Country code setting

3.8 Dump Mode

After the self test, the printer enters the dump mode. In this mode, any characters sent from the host computer will be printed in two columns, as shown. The characters received will be shown in the first column, and their corresponding hexadecimal values, in the second. This is often helpful to users for the verification of programming commands or debugging of printer programs. Reset the printer by turning the POWER switch off and on.

4. USING K4350/4350C

4.1 Power-on Utilities

There are three power-on utilities to set up and test K4350/4350C hardware. These utilities are activated by pressing the FEED or PAUSE button and turning on the printer power simultaneously. The utilities are listed as below:

1. Self-test
2. Gap sensor calibration
3. Printer initialization

4.1.1 Self Test Utility

Install the label first. Press the FEED button and then turn on the printer power. Do not release the FEED button until the printer feeds labels. The printer performs the following items:

1. Calibrate label pitch
2. Print out thermal print head check pattern
3. Print the internal settings
4. Enter dump mode

Regarding the self-test and dump mode, please refer to section 3.7 "Self Test" and section 3.8 "Dump Mode" for more information.

4.1.2 Gap Sensor Calibration Utility

This utility is used to calibrate the sensitivity of gap sensor. Users may have to calibrate the gap sensor for two reasons:

1. The media is being changed to a new type.
2. Initialize the printer.

Note: The ERR. LED may flash if gap sensor is not calibrated properly.

Please follow the steps below to calibrate gap sensor:

1. Turn off the printer power and install blank labels (without any logo or character) on printer.
2. Hold down the PAUSE button then turn on printer power.
3. Release PAUSE button when the printer feeds labels. Do not turn off printer power until the printer stops and two green LEDs light on.

4.1.3 Printer Initialization

Printer initialization clears all downloaded files resident in flash memory, and sets printer parameters to default values.

Parameter Default	Value Cleared by Initialization
MILEAGE N/A No
FLASH TIMES N/A No
CHECK SUM N/A No
SERIAL PORT 96,N,8,1 Yes
CODE PAGE 437 (8 bit), USA (7 bit) Yes
COUNTRY CODE 001 Yes
SPEED	2.0"/sec	Yes
DENSITY	09	Yes
SIZE	N/A Yes
GAP(BLINE)	N/A Yes
TRANSPARANCY	05,05,05	Yes

Please follow the steps below to initialize the printer:

1. Turn off the printer power.
2. Hold down the PAUSE and FEED buttons and turn on the printer power.
3. Do not release the buttons until the three LEDs flash in turn.

Note: Printing method (thermal transfer or thermal direct printing) will be set automatically at the activation of printer power.
