sensor

Two electrical contacts are attached to the ink cartridge holder in the carriage unit,
and when the ink cartridge is installed, the metal pins built into the ink cartridge
touch these contacts. “he IE (ink end) sensor circuit applies a HIGH level signal
when performing the ink end status detection operation. The ink level is
determined by the resistance between the two contacts by measuring the input

signal level with analog port ANO (pin 73) of CPU.

4. Thermistor

A thermistor is attached to theprinthead unit to monitor its temperature. The CPU

changes the printhead drive signal’s pulse width (charge pulse width) based on the

The flushing counter consists of the following counters.

CL Counter K

This counter indicates the amount of ink that exists in the cap, in
proportion to the number of flushing operations. When the counter

value exceeds or equals 3000 (R 2 3000), the printer performs the
false absorbing operation.

This counter is used to keep a wet condition inside the cap.
The flushing operation is performed based on the counter N value at
the flushing position, when the printer is in the standby state.

This counter is used to switch cleaning operation mode, to prevent an excessive ink drainage. The

counter value is changed when

This counter prevents excessive ink drainage to the waste ink drain tank by

selected when the counter value is equal to or exceeds 10 (B> 10), the printer
only performs the false charging operation.

This counter is used to prevent a continual initial charge operation. If the

BI-DIRECTIONAL

The bidirectioml printing alignment adjustment is required after you have
mechanism or replaced the main board. This adjustment lets you determine the compensation
value required to adjust deviations in the print position caused by the different print speeds that
result from the slight variations allowed within the tolerances of the mechanical components. The
adjustment modifies the print timing between odd-numbered lines and even-numbered lines in
