(3) Satisfactory Print with
Other Problems
This section covers problems that do not cause the
printer to stop printing nor produce unsatisfactory
prints. These situations are warnings that more
serious problems might be on the way.
Q15 Shouldn't I shake the ink can before I
install it in the printer? I always have
to shake paint cans.
S15 No. Never shake a can of Diagraph ink. The ink
in the can is actually in a bag that is attached to
the fitting at the top of the can. The can has
been pressurized with air that pushes against the
sides of the bag and forces ink through the fit-
ting. If vigorously shaken, the bag can tear loose
and ink will not flow from the can.
Q16 Do I need to cover my I.V./700 printer
during a washdown?
S16 Yes.
Q17 I've noticed ink accumulating on the
faceplate. Is this normal?
S17 Yes. Over the course of an 8-hour shift enough
ink may accumulate to form a hanging drop.
This ink may allow environmental debris to
accumulate, which is why the frontplate
should be wiped after at the beginning and
end of each shift.
Q18 I'm running the I.V./700 eight hours per
day and have to replace the ink can ev-
ery other day. Is this normal?
S18 Perhaps. Each can of ink will print approxi-
mately 225,000 characters. Actual usage var-
ies depending upon operating conditions.
Q19 I see ink in the receptacle for the ink can
when I install a new can. Is this normal?
S19 Yes. A few drops of ink may accumulate each
time the ink can is changed, eventually build-
ing up if not cleaned away.
Q20 Ink is leaking from the fitting where the
ink line attaches to the controller. What
should I do?
S20 Replace the lower enclosure assembly of the
controller (P/N 5750-207).
Q21 Ink is leaking from the fitting on the pig-
tail from the printhead? Is this normal?
S21 No. Replace the fittings. Use P/N 5750-214
for the female and 5750-213 for the male.
Q22 What parts should I expect to replace
after a year of 8-hour-per-day usage?
S22 None in a normal environment. Generally, the
first thing to fail is the printhead, which lasts
over a year.
