Control Description/Option
Fusing The fuser temperature control in the engine is a complex algorithm that is based on the
print mode and print-duty cycle. An “increase” or “decrease” in fuser temperature means
that the fuser control algorithm increases or decreases the current temperature target
by some amount, which depends on paper type and other factors.
The following settings are available for the Fusing control:
●
No adjustment.
●
Paper curl-up and Paper curl-down. These settings change the optimum fusing
temperature to 1/2 speed for light and rough paper (such as Neenah Bond 16 lb.)
and can help prevent paper curl and poor fixing performance for these kinds of
paper.
●
Flap sealing.
●
Less Fusing/More Fusing (-2, -1, +1, +2). These settings allow the user to adjust
the fuser temperature up or down one level. Use this setting to find the best balance
for the print job when other adjustments are insufficient.
Transfer The transfer bias voltage control in the engine is a complex algorithm that is based on
the print mode, toner cartridge, and humidity. An “increase” or “decrease” in transfer bias
means that the transfer control algorithm increases or decreases the transfer bias by
some amount, which depends on paper type and other factors.
The following settings are available for the Transfer control:
●
No adjustment.
●
Dry paper. This setting is appropriate for products that are in an environment with
low humidity. It shows PQ defects with high-resistive paper.
●
Rough paper.
●
Humid paper. This setting is appropriate for products that are in an environment
with high humidity. It sets Glossy Film as thePrint mode and it also shows PQ
failure.
●
Less transfer/More transfer (-5, -4, -3, -2, -1, +1, +2, +3, +4, +5). These settings
provide one level of decreased transfer bias voltage and one level of increased
transfer bias voltage if the other adjustments are insufficient. Try adjusting these
settings to find the best balance for the print job. In extreme case (very dry or very
wet), low-transfer current defects and high-transfer current defects can overlap;
that is, a defect-free setting might be impossible. These adjustments can help find
the best operating point.
Duplex Transfer Paper becomes much drier and develops a higher resistivity after it has printed on the
first side and has passed through the fuser. The changes to the paper can result in
transfer defects on the second side of the paper. To help prevent this situation, the
product engine uses different transfer bias settings for printing on the second side of the
paper.
The following settings are available for the Duplex Transfer control:
●
No adjustment.
●
Dry paper. See Dry paper in the Transfer control row.
●
Humid paper. See Humid paper in the Transfer control row.
