4.5 Reset 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 notused, the parts enclosed by dotted lines are not required.

4.6 Oscillation 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.

4.7 Head-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.

CBM-202PC-04 User’s Manual

4.8 Head 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 printinghead.

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.

17 CITIZEN

4.9 PaperEnd 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 (Pin7) 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,
printingis 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 ParallelInterface 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 whenthe power has beenalready turned on. The printer automa ticallystarts self-printing and returns
to the normal waiting state after printing is completed.)

4.15 ErrorOutput 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 paper runs
out, and "HIGH" is output when new printing paper is set. LEDER(Pin 3) of the CPU outputs other errors
in the follow ing patterns.
