4.5Reset Circuit

The reset state is effectuated by setting the RES terminal to "Low." To surely reset, it is necessary to set it to "Low" at least for 20ms at power -on and for 625ns while operating.

If an external reset is not used, the parts enclosed by dotted lines are not required.

4.6Oscillation Circuit

The oscillation circuit incorporates a clock oscillator which generates a system clock and an internal clock. There are two methods to supply a clock; one is to connect a ceramic oscillator, and the other is to input an external clock.

When using the ceramic oscillator, we recommend the CSTCS16.00MXOC3 (With capacitor) made by MURATA. When inputting the external clock, you may either open the XTAL terminal or input an antiphase clock to the XTAL terminal.

4.7Head-up Detection Circuit

Print head up/down is detected by a head-up sensor built in the printer so that the printer will not be energized on with the head up. The circuit is "opened" when the print head is up, and "closed" when down.

When the print head is up, HEADUP (Pin 88) of the CPU is turned to "High," and if the printer is printing, it will immediately stop printing and output an error. It resumes printing when the print head is down.

16

CITIZEN

CBM-202PC-04 User’s Manual

4.8Head Control Circuit

VP is controlled in order to prevent electrolytic corrosion of the printing head. HVC(Pin-4) of the Gate Array is turned to "HIGH" when turning on VP, and turned to "LOW" when turning it off.

A temperature detection circuit is provided in order to prevent deterioration of the printing quality or breakage of the printing head due to a temperature. This function detects a temperature by means of a thermistor included in the printer and determines according to that temperature how much energy should be applied to the printing head. If a temperature of the printing head exceeds 60•, it will stop printing to prevent breakage of the printing head.

As a protection when the CPU crashes, connect in such a manner that the Gate Array will be reset by an output from the watchdog timer of the CPU. The CPU itself has been set so that it will be reset. So that the head strobe will not be turned to ON at that time, be sure to insert one pull -up resistor into STRB1 through STRB3, respectively.

4.9Paper End Detection Circuit

A paper sensor built in the printer detects whether there is the printing paper, so that the printer will not be turned on when it has no paper.

When the printer has no paper,PAPER (P in 7) of the CPU is turned to "HIGH." If printing is under way, it will stop after printing that line, and output an error. When the paper is set, printing is automatically resumed.

4.11 Auto Cutter Control Circuit

This CPU has a function to control the auto cutter, using the Pin 33 of the Gate Array.

When the auto cutter is not used, set the Pin 33 of the Gate Array to "HIGH." If se t to "LOW," the printer will not function properly, resulting in an alarm.

4.12 Parallel Interface Circuit

The Gate Array ports are mainly used to provide an 8-bit parallel interface.

When the parallel interface is not used, pull up STB(Pin 52) of the Gate Array with a 10kΩ resistor. STB(Pin 87) of the CPU should be connected to INTR(Pin 56) of the Gate Array or pulled up with a 10kΩ resistor.

4.14 Switch Circuit

The printer has a switch input function for paper feed. Also provided is a function to perform self -printing, using this switch. (Turn on the power while holding down this switch, or apply a reset with this switch held down when the power has been already turned on. The printer automatically starts self-printing and returns to the normal waiting state after printing is completed.)

4.15 Error Output Circuit

The printer has two kinds of error outputs. (Up to a current of 10mA is available in order to mainly indicate with the LEDs. If this limit is exceeded, the CPU may be destroyed. Select the current control resistors, LEDs, etc. carefully.)

LEDPE(Pin 4) of the CPU is a paper error exclusive output. "LOW" is output when the printing pap er runs out, and "HIGH" is output when new printing paper is set. LEDER(Pin 3) of the CPU outputs other errors in the following patterns.

1)	Error output pattern
	Error		Display Pattern	Description
Memory error				Blinks at intervals of 200 ms
Cutter lock				Blinks at intervals of 150 ms(6 times) and 500
(Cutter error)				ms(1 time) as one cycle.
Head-up				Illuminated until the error is reset.
VH voltage error				Illuminated until the error is reset.
Head temperature				Blinks at intervals of 1 sec.
error
Macro execution wait				Blinks at intervals of 500 ms
2)	Error descriptions
	Error			Description
Head-up			The head-up lever has been shifted up.
VH voltage error			When the VH voltage is beyond an allowable range (4.2 ~ 8.5V)
Head temperature error			When a head temperature is less than 0°C or 65°C or more
Cutter lock			When the cutter is locked due to an external factor (Paper jam, etc.) at cutter
(ASC-220-5V)			drive time

Note) The upper-limit voltage of 8.5V for the VH voltage error is a voltage assumed only immediately after charging the battery when the battery power is used and cannot be normally used. A maximum normal voltage is 7.2V.

	Head-up	Shift down the head-up lever.
	VH voltage error	Set the VH voltage to within the allowable range(4.2 ~ 8.5 V) and turn on the
		power again, or set the LFSW(Pin-2) of the CPU to Active. See Note 2.
	Head temperature error	At the lower limit(Less than 0°C), printing is enabled at 0°C or more.
		At the upper limit(65°C or more), printing is enabled at 60°C or less.
	Cutter lock(ACS-220-5v)	Eliminate the paper jam and set LFSW(Pin-2) of the CPU to Active or turn
		on the power again.
	Note)

1.If auto loading has not been selected with the function selection J4(Jumper), set the paper manually. If it has been selected, the auto loading function will be enabled to facilitate paper replacement.

2.The upper-limit voltage of 8.5V for the VH voltage error is a voltage assumed only immediately after charging the battery when the battery power is used and cannot be normally used. A maximum normal voltage is 7.2V.
