Heater Duty Cycle
The purpose of the heater duty cycle is to ensure adequate drying of the ink in order to
avoid undesired printing artifacts such as bleeding, pooling, fisheyes, etc. Drying is
affected by multiple factors including the media used, image density, ink temperature,
air temperature, and other environmental factors. Consequently, it is not possible to offer
a set formula that covers all printing scenarios. Therefore, it is the responsibility of the
operator to determine the optimum heater duty cycle to ensure adequate drying for any
particular print job.
Caution: Using too high of a heater duty cycle can cause
print head nozzles to dry out resulting in banding artifacts in
the image. Acceptable ink zone temperature is from 32C to
38C (90F to 100F).
There is an important distinction between drying and curing. Drying involves
Note:
providing sufficient heat to the media so that the ink is not affected by
subsequent passes of the print heads. It is determined by the heater duty
cycle. Curing is the process that ensures the media, with its printed image,
can be safely handled without smearing or otherwise degrading print quality.
It is determined by time and various environmental conditions.
Move through the displayed digits using the ACCEPT key. The selected digit has an
underline indicating it can be increased or decreased using the + or - keys. Only the first
two digits can be changed. The first digit can only be a 1 or a 0 — pressing accept when
the 1 is displayed automatically set the value to 100%. To set a value less than 100%,
change the first digit to 0, press ACCEPT and then change the second digit using the +
or - keys. When you have set the second digit, press ACCEPT to go the third. After
setting it press ACCEPT to the "Place media on table" menu, or to the Change Offsets
selection menu if this was enabled in the Change Print Parameters menu.
