On occurrence of framing error, overrun error, or parity error, the data is printed as “?”. (2) DTR When this signal is READY, write data or a command. When they are written in BUSY, overrun error is occurred and data is ignored. Data can be written into the input buffer even when the printer is busy printing. A BUSY also occurs when the printer is powered on, in test print, in Online mode, or being reset. (3) TXD If data remaining in the printer's input buffer is 256 bytes or less, the printer transfers a DC3 (13H: Data Receive Not Ready) signal to the host. If data in the input buffer exceeds 256 bytes, the printer transfers a DC1 (11H: Data Receive Ready) signal to the host. (4) GND Common GND on the circuit. 7.3 Error Detection Parity, framing, and overrun are detected. On detection of any error, the data are stored in the buffer as “?”. (1) Framing Error With “space” state having been detected on detection of a stop bit, error takes place. The data are stored in the buffer as “?”. (2) Parity Error With an error having been detected under specifying parity check, the data is stored in the buffer as “?”. (3) Overrun Error On detection of an overrun error, the data are stored in the buffer as “?”. 7.4 Data Receiving Control When DTR/DSR control having been selected, with BUSY signal at “LOW”, data from the host side are received. With the signal at “HIGH”, they can not be received. When DTR/DSR control not having been selected, after X-ON transmission, data is received from the host side. No transmission of data can take place after X-OFF is transmitted. 14 BD2-2880/2890 User’s Manual 7.5 Buffering Data transfer to the input buffer include DTR signals and TD signals as the control signals concerned.

Cutter lock When driving the cutter, the cutter is locked due to an external factor (Paper (ACS-220-5V) jam, etc.). Caution: The 8.5V upper-limit voltage for VP voltage error is only an assumptive voltage just after charging the battery when using the battery power. It cannot be normally used. A normal maximum voltage is 7.2V. (2) External signal outputs 16 BD2-2880/2890 User’s Manual Pin No Signal Name Remarks 20 ERROR LED output.

Head –up Bring down the head-up lever. VP voltage error Set to a voltage within the allowable range (4.2 to 8.5V) and turn on the power again. Alternatively, activate the Pin19 (LFSW) of the CN3(interface connector). Head temperature At the lower limit (less than 0 ˚C), printing becomes operational at 0 ˚C higher. error At the upper limit (65 ˚C or higher), it become operational at 60 ˚C or lower. Cutter lock Eliminate paper jam and activate the Pin19(LFSW) of the CN3(Interface Connector) (ACS-220-5V) or turn on the power again. Caution: Note 1. When auto loading has not been selected with the function selection jumper (J4), set the paper manually. When it has been selected, the auto loading function is enabled to facilitate replacement of the paper. Note 2. The 8.5V upper-limit voltage for VP voltage error is only an assumptive voltage just after charging the battery when using the battery power. It cannot be normally used. A normal maximum voltage is 7.2V. 17 BD2-2880/2890 User’s Manual 8.3 Errors Indication The errors other than no paper are indicated by a LED output (Illumination or blinking) of the Pin 20 (ERROR) of the CN3 (Interface connector).

PRINTER MECHANISM CONTROL SYSTEM 9.1 Thermal Head Control System (Division Driving System) The MLT-288 (Line thermal printer) is driven by this control board has a384 dots/line head divided into 6 blocks of 64 dots each. When actually driving the head, you can select either Fixed Division Number system, which drives the head, always dividing it into 6 blocks or Variable Division Number system which collectively drives several blocks at the time according to the number of activated head dots. For selection by function selection, see 4. DIP SWITCH SETTING. For selection by a command, see 11. PRINT CONTROL FUNCTIONS. 9.1.1 Fixed Division Number System This system always drives each block in the same sequence. 1st Block 2nd Block 3rd Block 4th Block 6th Block 5th Block 64 Dots 64 Dots 64 Dots 64 Dots 64 Dots 64 Dots 1 Dot Line 1st Step of Motor 2nd Step of Motor Note: for a stepping motor driving method, see 9.2 Motor Drive. 9.1.2 Variable Division Number System This system counts the number of printing dots for each block of the printing dot line and drives the blocks collective in such a manner not to exceed the maximum number of driving dots (64 dots). 1st Block 2nd Block 3rd Block 5th Block 6th Block 4th Block 64 Dots 64 Dots 64 Dots 64 Dots 64 Dots 64 Dots 1 Dot Line 1st Step of Motor 1st Step of Motor 2nd Step of Motor 2nd Step 19 BD2-2880/2890 User’s Manual 9.2 Motor Drive The MLT-288 uses a 4-phase bipolar stepping motor. It feeds the 1 dot line worth of paper in two steps by 2-to-2 phase excitation. 9.2.1 Motor Drive Features 1) Drive at an optimum drive speed by the VP voltage. 2) Prevents heat generation of the motor by PWM control to restrain current consumption. 3) Provides acceleration control at the time of start. 9.2.2 Maximum Motor Drive Speeds at Major Voltage VH Voltage Motor Drive Speed 5V 400pps 6V 600pps 7.2V 840pps Caution: The maximum drive speed depends on the VH voltage. A printing speed may slightly differ depending on a processing time or voltage detection accuracy. During the course of printing, a motor drive speed may be slower than the maximum drive speed, depending on what is printed or the head divided drive system. 20 BD2-2880/2890 User’s Manual 10.
