5.10.2 Standard Pattern Printout (T&D 10)
In this test the printer prints a patter with a lot of information to check all the correct functionalities.
If the T&D9 was previously done and the same sheet used is loaded, the printers automatically prints the
whole pattern as indicated in next figure 5.5A, otherwise a blank area appears in correspondance of the
T&D19 pattern.
At the beginning of this test is also checked the presence of mechanical options (MSRW /MICR).
On the pattern is printed the result of this test:
OPTIONAL DEVICE NOT FOUND (not detected)
OPTIONAL DEVICE <Iidentify device>
In the case in which the optional device is present, but in error, the pattern is halted and the specific error condition
are displayed on the operator panel with the printout::
OPTIONAL DEVICE FAULT
1. The paper is loaded with 8 step less than the stored value of the first printable line, than it prints:
- 4 underlined signs on the left and right sides to check the loading line skew.
- 9 groups of “EE” separated by a space with an incremental vertical paper movement of 1/180”
between each group (from –8 to +8 values).
Under each group except for the central one (0 value) is printed the check marker which must be
signed after the end of the test .
- A continuous line is printed for the reference of the step 9.
2. A line is printed with the controller code ID and version, the character generator ID and version, the
quantity of Ram size and the release of built -inT&D.
If the LAN interface is installed its status, version and MAC address are printed.
3. In the following two lines are reported :
The current Adjustments parameters as indicated in previous chapter (F.Col, F.Lin, Bid, White) and
also the themperature of the print head (T) in degrees.
The Log parameters of the T&D (see chapter 5.11).
4. A complete pattern which exercises all the 24 needles of the printer (the single bar printed on the right
side is the specific printed needle reported below).
5. A paper movement test (with forward and backward movements) composed by:
A) First the printer prints the first and third chopped-lines.
B) After the point 12. a backward movement is made and the central chopped-line is printed.
This line must be between the two previous chopped-lines.
6. A special vertical bar pattern to choose the best vertical alignment.
The first time this test is printed, the 5 lines show the current value in the middle line (3rd line)
associated with an asterisk (*) with the other two lines before and after with the value immediately around
the current one associated with a check marker which must be signed after the end of the test .
7. Six patterns of characters set with different type of printing attributes (CPI e Quality).
8. A special mono-directional bars pattern is printed to check the correct most external white-colored guide
print-head needle position. If this lines are not regular, the problem depends by the print head itself and
not by a vertical disalignment (carriage movement).
