Are the properties set correctly in the print driver.
You can turn certain colors up or down.
Does is copy magenta?
If so I would suspect the driver or the settings within the driver.
If it does not copy magenta, then I suspect a developer housing issue.
Printing only then suspect a driver issue.

37,0XX.xx Errors - PEST Faults
AC power supplied by power sources such as uninterruptible power supplies
(UPSs) or DC-to-AC inverter systems may not supply correct voltage to
properly power up the printer. Likewise, other devices sharing the same AC
circuit can cause AC voltage sags that cause the printer to fail its AC heater
PEST tests (Print Engine Self Test). The printer may produce any of the
following disconnected heater errors:
■ Printhead jet-stack 37,002.47 or 37,003.48
Error Messages and Codes
■ Reservoir heater, 37,004.40 or 37,005.41
■ Drum heater error 37,006.42
■ Preheater error 37,008.44
■ Ink melters errors 37,009.45 thru 37,013.40
The printer includes several heaters powered by AC. The printer itself can
power up despite insufficient or irregular AC voltage but it may fail its AC
heater tests. This is due the test not measuring sufficient current flowing
through the heater at the moment the test runs.
Devices sharing the printer’s AC circuit shared, such as a laser printer, a
coffee maker, or a space heater, may be placing heavy intermittent demand
on the AC circuit. This sudden inductive demand creates momentary AC
voltage sag that causes the PEST test to fail.
Verify the AC power source prior to troubleshooting these errors. For wiring
diagrams to aid in diagnosing PEST faults, see “Wiring Diagrams” on
page 10-1.
8400/8500/8550/8560 PEST Description
37,001.46: Generic PEST error. Something went wrong during the PEST process.
37,002.47: PEST Error - Printhead Left jetstack disconnect. The left jetstack is
not drawing the expected power from the supply.
