Overview
When making adjustments, be aware that interdependencies exist between parameters (e.g.,
parameter changes which reduce warp could induce partial transfer).
There are four basic parameters to control, and these parameters differ for single- and double-sided
printing for each card type:
y Front transfer temperature (upper roller temperature in degrees Celsius)
y Back transfer temperature (lower roller temperature in degrees Celsius)
y Input transfer speed (speed entering the print station in inches per second)
y Output transfer speed (speed exiting the print station in inches per second)
It is very helpful to think about the energy being put into the card as opposed to just temperature.
Speed parameters are the “big knobs” for adjusting energy, while temperature parameters are the
“ne tuning knobs.” Slowing down only 0.1 inches per second (IPS) has almost twice the energy-
increasing effect as raising the temperature 5 degrees. In terms of energy:
y Far too little energy = no transfer at all
y Not enough energy = partial transfer
y Too much energy = card warp
y Far too much energy = card jams caused by severe warp
Speed
Going slower in can help guarantee good transfer, while going faster out can prevent the already-
transferred card from remaining hot long enough to soften, weaken, warp, and possibly even jam.
Usually, the most reliable and stable speed settings range between 1.2 IPS and 2.6 IPS, with lower
generally being better for most card types.
Temperature
A top temperature which is slightly higher than the corresponding bottom temperature normally works
well for double-sided transfer. For single-sided transfer, there will be signiîšżcantly lower temperatures
for the back side of the card to avoid accidental transfer. In general, a lower temperature difference
between the front and back sides will induce fewer warming/cooling cycles in the printer.
To compensate for interdependency issues, try adjusting the parameters as follows:
y Start by correcting any partial transfer issues by using the procedure outlined in “Partial
Transfer” on page 152.
y Then attempt to improve warpage by using the procedure outlined in “Warpage” on page
154. Start with acceptable settings from Step 1. While adjusting parameters, ensure that
the transfer quality remains acceptable. Do not continue reducing temperatures or increasing
speeds if the transfer quality becomes unacceptable.
