White Ink Option

Introduction
If your printer has the white ink option and white is not printed on a regular basis, pigment
settling can occur in the white ink printheads. During periods of white ink inactivity the printer
will automatically try to maintain the white ink channel using the following methods:
.
• ink recirculation
• spitting
• AMS cycles
Additional efforts may be required to recover nozzle performance for the white ink printheads.
CAUTION
Wear eye protection and nitrile gloves when handling or cleaning ink. Also, when working
around ink protect your clothing and any exposed areas of skin.
Recovering White Ink Nozzle Performance

2.
settings for printing (offsets, media thickness, lamp power, etc.).
3. Print and evaluate nozzle performance.
A general guideline is to do a standard AMS on the white ink channel if:
• more than 2 nozzles outs exist in a single printhead
• 2 or more adjacent nozzle outs exist in a single printhead
• more than 4 nozzle outs exist in a single color
4. If necessary, perform a standard AMS on the white channel.
Reprint the White Ink Nozzle Check Print to evaluate results.
5.
6.
If white ink nozzle performance is still not at an acceptable level, perform a long AMS on the
white channel.
Reprint the White Ink Nozzle Check Print to evaluate results.
7.
8.
If white ink nozzle performance is still not at an acceptable level, swabbing with flush is required.
9.
Dip the foam end of the swab in a small container of flush solution. For best results the swab
should be fully saturated with flush.
10.
Hold the flush-soaked swab against the area of the printhead where the nozzles requires recovery
for 10 seconds. See figure below.
