Table 3-7. This section describes the procedures for solving the problem
when an ink out (cartridge out) error is displayed even though
a brand-new ink cartridge has been installed.
Step Check Point
9 Have the cartridges been Because this printer uses a new type of cartridge, traces of
refilled? whether the cartridges have been refilled can basically be
checked. The reasons are as follows.
1. In contrast to previous CSICs, there is no ventilation
hole at the top of the cartridge. There is no refill point
like previously.
2. If a syringe is inserted through the film to charge the
inside of the cartridge with ink, a hole is made in the
film, and so the customer must use measures such as
applying tape in order to prevent ink from leaking out.
10 The data in the ink Of the many items of data stored in the CSIC chips, the
only item that is updated by the printer is the ink

1. Corrupt data in the CSIC chip. The cause of this might be
as follows.
1.1.The data was recorded incorrectly when the CSIC

2. A head hot error as described in No. 7 occurred. In such
cases, the data is not randomized as described above,
but the only part of the CSIC data that is changed is the
ink consumption counter. No data in any of the other
addresses is affected.

data in the EEPROM to be randomized, so that the
data became corrupted.
printers which used DC motors have a sequence
which forcibly changed the consumption status to
100% for currently-installed ink cartridges as a
result of customer error. However, this printer
does not have such a function. Accordingly, CSIC
problems relating to ink life should be analyzed
based on the above points.
