3-6 Ink System Overview
Spare Ink and Printheads For maximum productivity and minimum down time,
ColorSpan recommends stocking extra ink reservoirs and print-
heads. When the ink supply runs low, or a printhead needs to be
replaced, having spares will ensure that printing can resume as
quickly as possible.
Since ink and printhead usage will vary depending on the
amount and types of printing you do, experience will help you
determine how to stock an efficient spare inventory. For exam-
ple, in a “2x6” configuration (two six-color sets of ink),
ColorSpan recommends stocking two six-color sets of ink reser-
voirs, plus six printheads (one for each color). Both ink reser-
voirs in a pair tend to run out of ink at the same time, so two
spares per color would allow you to continue printing with a
minimum of delay. The printheads tend to need replacement
one at a time, so one spare per color would be sufficient most of
the time.

Jets” on page 5-3.
Printhead Handling Tips
◆
DO hold the printhead by the plastic body only.
◆ DO clean the printheads with a clean lint-free cloth moistened
with plain water.
◆ DO NOT touch the ink jet nozzles on the bottom of the printhead.
◆ DO NOT touch the electrodes on the back of the printhead. The
printhead is fired by an electrical signal. The electrodes that carry
this signal are easily contaminated.
◆ DO NOT set the printhead down anywhere before you install it.
◆ DO NOT wipe the printhead with any fiber-cellulose material,
such as a paper tissue.
◆ NEVER APPLY ISOPROPYL ALCOHOL ON THE PRINTHEAD OR
SERVICE STATION. USE PLAIN WATER. Alcohol reacts with pig-
mented inks, rendering the printhead unusable. To clean ink clogs,
see “Cleaning Ink Jets” on page 5-3.
