Automatic Color Adjust
Sets the suggested number of pages which the printer should print between consecutive calibrations.
Selections are
Off
and the values between
100
and
1000
in increments of 50. The default is 500 pages.
If the printer exceeds the set value while printing a job, it completes the current job and any other jobs received
while printing the current job before it initiates a calibration. The printer does not cancel or suspend an active job
in order to perform a calibration. If a user is in any of the menus, including the Configuration Menu and the
Diagnostics mode, an automatic color adjust calibration does not occur.
Auto Align Adj
Controls whether the printer executes the automatic alignment calibration after an initiating event occurs. When
an event initiates a TPS operation, the printer performs a toner density calibration, (TPS) an alignment
calibration, or both of the calibrations.
Toner Patch Sensing (TPS) is a diagnostic mechanism that automatically adjusts the printer toner density and
alignment settings. When TPS executes, the printer generates toner patches on the transfer module. It then
uses these to calculate the appropriate adjustment, to density, if necessary.
Selections are
On
(default) and
Off
. Turning this setting to
Off
is not recommended for normal operation
because it prevents the printer from using the results of automatic color calibration and automatic alignment to
make minor adjustments. Eventually, the user will have to manually correct alignment and color on the printer.
Color Adj State
These settings allow you to select when color calibrations occur. Selecting
Busy
indicates the color calibrations
will complete queued jobs, but refuse to add new jobs to the queue. When calibration is complete jobs are again
accepted. Selecting
Idle
allows calibrations only when the printer is idle.
Enforce Color Order
This setting gives the system support person the ability to enforce where the color cartridges may be placed,
and if messages appear when cartridges are in the wrong location.
When
On
(default) is selected, the printer lets users place each toner cartridge in only its specified slot. For
instance, the Magenta toner cartridge must be in the Magenta slot. If the user tries to place a cartridge in an
incorrect slot, the printer message
31 Defective or Missing < color > Cartridge
or
32 Unsupported < color >
Cartridge
appears where <
color
> stands for Cyan, Magenta, Yellow, or Black.
When
Off
is selected, the printer does not issue any message to let the user know that the cartridge is placed in
the wrong slot inside the printer.
Color Alignment
Color alignment should be performed when the printhead may become misaligned because it was removed or
replaced. Perform Color Alignment when a new transfer belt assembly is installed.
To perform color alignment:
1.
Select
Color Alignment
from the Configuration Menu.
2.
Select
Print Alignment Page
.
3.
Select
Set A
.
Consulting the printed page, follow the instructions on the operator panel to choose the best appearing line
numbered 0 through 20 for line A.
Continue selecting the best lines for the sets through
Set L
.
