•
area 2 is used to evaluate that the
transport speed
of the print carriageis uniform:
no shadings should result in the strip
•
area 3 is used for checking
vertical alignment
; run the printer alignment test, if
necessary, to modify the alignment parameters (see section 6.1.1)
•
areas 4, 5 and 7 are used for checking that the
line feed mechanism is uniform
:
- in area 4, groups of lines are printed close together but must never cross or
overlap (
); the groups alternate in lines corresponding to the
central nozzle on the print head (number 25)
- in area 5, groups of lines are printed one on top of another and there must be
no space between them (
); the groups alternate in lines
corresponding to the central nozzle on the print head (number 25)
- in area 7 dark grey and light grey patterns are printed forming a uniform strip,
that is, without black or white lines distributed irregularly across it; if the lines
appear at regular intervals along the strips, some of the nozzles are faulty
Faults found in areas 4, 5 and 7 indicate line feed errors
•
four areas 6 are used for checking "
all black
" printing; check that there are no
white lines present; if there are, some print nozzles may be blocked. In this case,
run CLEANING (see section 6.1.3)
•
area 8 is used for checking the printing of
ASCII characters
•
area 9 is used for checking printing with the nozzles spraying at
maximum
frequency
: there must be no white or broken lines; if there are, run the nozzles
test (see section 6.1.2).
