sounds to me like one of two things has happened.
More than likely the actuator tab on the cover snapped off,
Look for an opening around the edge of the cover , there is a cover interlock switch in there. Note its position and look at the cover to verify there is a tab on the cover to actuate the switch, Or you may have a loose connector on the interlock switch, or a bad switch, although I have never seen one of those switches go bad.

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 the following heater errors:

37,005.41: PEST - Printhead Reservoir 1 disconnect. Reservoir 1 is not drawing
the expected power from the supply.
If the printer is plugged directly into a wall outlet and you still get this error, the Printhead is bad and should be replaced.

This fault code indicates a problem with the process control system. The machine cannot successfully home the transfix mechanism.

Check for obstructions around the printhead. Look for ink shards in the gears of the tilt drive. Check the printhead wiring harness to make sure it is not blocking the printhead movement (left/right & front/back). Remove the waste ink tray and look for ink build-up.

Check the process drive gears for damage. Ensure the gears are correctly aligned and homed.

Check the nose cone alignment on the X-Axis motor. Is the nose cone aligned with the printhead shaft (left/right movement).

When you removed the square metal block from the printhead shaft on the Left side, did you reinstall it with the "dot" in the same orientation as the diagram above it shows with a check mark?

You can download the Print drivers from HERE. Make sure you select the PostScript Driver v5.48.30 or you can as well use the Global Print Driver, which you can download from the same link. Uninstall previous drivers and Install it as a Local Printer. Please be aware that if you are using a Server/Client structure the this instalation should be done on the Print Server.
After all that you should be able to print in colour. As a test print an Image file and make sure you confirm colour is enabled on the printing preferences of the driver. Alternative would be to print a test page from the driver. This will also show you the colour prints.

The machine displays the Replace Maintenance Kit after the Maintenance Kit has been replaced.
There may two causes for this issue.
  1. The machine does not recognize that the Maintenance Kit was removed. This would likely be caused by a defective Drum Maintenance Pivot Plate.
  2. The machine corrupts the CRUM on the new Maintenance Kit. This may be caused by a defective Drum Maintenance Pivot Plate or IO Board.
Solution: thumbsup.gif Fixed! thumbsdn.gif Did not fix.
  1. While the Replace Maintenance Kit message is displayed, remove the Maintenance Kit. If the displayed message does not change to "Maintenance Kit Missing," replace the Drum Maintenance Pivot Plate and install a new Maintenance Kit.
  2. While the Replace Maintenance Kit message is displayed, remove the Maintenance Kit. If the displayed message changes to "Maintenance Kit Missing," replace the IO Board and then install a different NEW Maintenance Kit. If the problem persists, replace the Drum Maintenance Pivot Plate and install a different NEW Maintenance Kit.

1. Open Start menu.
2. Click on "Printers and Faxes"
3. Double-click the icon for your printer.
4. On the menu bar, click "Printer" to open the printer menu. Click on "Use Printer Offline" to remove the check mark. This will bring your printer back online.

If this did not help, check the printer itself & make sure it is not set to be offline.

First look at your printer identification.

You can see it in either the display or on the startup or configuration pages.

It must have a "D" in the name for you to be able to do automatic duplexing. i.e. 8400DN or 8400DX . Then you can scroll to printer setup
and select defaults, and then turn on the duplex, or double sided printing.

If yours does not have a "D" i.e. 8400, 8400N then you would need a new sim card to enable the duplex option.

When you go into the eliminate light stripes there is also a mode called Jet Substitution. You can sometimes bypass the bad jets.
If that does not work then the print head will most likely need to be replaced.
You can replace the printer for less than the cost of a print head normally..
