Okidata 320/420 printhead not printing aligned.

Blocked Printheads and/or Alignment issues.
Try cleaning the printheads and see if there are any increases in quality. Then start down the alignment road. Be very careful when tinkering with alignment. If you mess it up it may require a technician to realign it properly.

Unplug power, look down on printhead some have a chrome metal clamp that swings out and then you pull up on print head. Some models have two screws that hold print head in. Then the print head pulls up.

Your ribbon needs to be adjusted. The printhead is not aligned with the ribbon.

this sounds like a print head issue. a replacement printhead is the way to go.

This is from the service manual. The lobes on the camshaft that rotates the maint kit up are know to crack. If they have rotated on the shaft this could cause your problem.
If you remove both sides and home everything it will come ready as long as nothing is broke

The 7,007.49, 7,008.41, 7009.42, and 7,010.43 errors indicate that the
Printhead was unable to tilt normally on its axis. Possible causes include:
??  The printer was powered off in the middle of a cleaning cycle and the
Wiper Blade has frozen to the Printhead.
??  A Drum Maintenance Camshaft lobe is broken and holding the Drum
Maintenance Kit’s oil roller against the Drum when it should be retracted
to its home position.
??  Process Drive not being aligned correctly.
??  A damaged Printhead Restraint.
??  Ink spilled in the Roll Block preventing proper Printhead motion.
??  Ink or other debris under the Printhead preventing proper motion.
??  The Wiper Assembly not being aligned correctly or ink spilled in the wiper
tracks.
??  The Head Tilt Gear not being homed correctly.
??  The X-Axis Motor nose cone not being installed correctly.
??  The ferrite torrid on the Printhead interface cable has slipped behind the
Printhead causing the Printhead to bind when it tilts backwards.
??  The black plastic shroud on the back of the Printhead is snapped off and
binding the Printhead when it tilts back.
Caution
After servicing the printer, manually set the following assemblies to their
home position before powering on the printer. See Section 6 for
instructions on setting these components to their home positions.
??  Printhead (tilted forward and disengaged from Printhead tilt gear)
??  Head Tilt Gear (disengaged from Process Drive train; arrows on left
frame point to each other)
??  Wiper Assembly (bottom of travel)
??  Process Drive (holes on Transfix Camshaft and Drum Maintenance
Camshaft line up with marks on frame, large gears within assembly
line up with holes in Process Drive housing)

When you removed the paper it's possible your damaged it and that's why the message is not going away. Did you try to put the cartridge back in to make sure it had not come out of position and just remove the power cord for a minute then plugging it back it.

Here are the steps to make sure you properly change the cartridges and the heads...

Install the ink cartridges and printheads Step one: Install the ink cartridges All four ink cartridges must be correctly installed for the HP All-in-One to work. Follow the steps below to Install cartridges:

1. Open the ink cartridge cover.
2. Remove each ink cartridge from its package.
3. Align each ink cartridge with its color-coded slot and then insert the ink cartridge into the slot. To ensure proper contact, press down firmly on the cartridges until they snap into place.
4. Close the ink cartridge cover.

Figure 1: Installing cartridges 1 - Open the ink cartridge cover. 2 - Remove the ink cartridges from the packages. 3 - Install the ink cartridges. 4 - Close the ink cartridge cover. Step two: Install the printheads Follow the steps below to install the printheads.

1. Open the top cover of the printer. Figure 2: Open the top cover
2. If the carriage does not move to the left automatically, press and hold the Resume button ( ) for three seconds. Wait for the carriage to stop moving.
3. Remove the cardboard cover from the printhead carriage. Figure 3: Remove the cardboard cover
4. Lift the printhead latch. Figure 4: Lift the printhead latch
5. Before installing a printhead, shake the printhead up and down at least six times while the printhead is still in its packaging. Figure 5: Shake the printhead while it is still in its packaging
6. Remove the new printhead from its package, and then remove its orange protective caps. CAUTION: Do not shake printheads after the caps are removed. Figure 6: Remove the printhead from its packaging, then remove the orange caps from the printhead
7. Insert the printhead into its color-coded slot. The label on the printhead must match the label on the printhead latch. Press down firmly on the printhead to ensure proper contact. Figure 7: Insert the printheads in the correct color-coded slots
8. Pull the printhead latch all the way forward, and then press down to ensure that the latch is properly engaged. You might have to apply some pressure to engage the latch. Figure 8: Close the latch
9. Close the top cover. Figure 9: Close the top cover

Step three: Align the print heads Whenever you insert or replace a printhead, the printer automatically aligns the printheads to ensure the best print quality. If the printer does not print the alignment page automatically, start the alignment process manually. To start the alignment process manually:

1. Press the Setup button on the control panel Setup and the number 6 on the keypad or scroll to Tools .
2. Press 4 on the keypad or scroll to Align Printer . The alignment process starts.

Things to check:

1. Move the pressure arm further towards the outside of the printhead. Adjust if needed using only the minimum pressure required in order to achieve uniform print quality.

2. Inspect the printhead to ensure it has properly engaged the alignment pins. I have had after-market printheads that did not line up correctly and required "surgery" to make them properly seat on the mounting pins.

3. Check for worn platen roller bearings. If they're are sufficiently worn, one side of the platen roller will be slightly lower than the other.

4. Consider replacing the platen roller. They do wear out and require replacement. Zebra part number 40038M IIRC.

5. Check the printhead parallelism adjustment. The procedure is in the maintenance manual.

Your printhead is in correctly but not aligned, Please loosen the 2 screws that holds the printhead.Remove ribbon(all this while the printer is powered off) Now look on the right side there is a lever that makes the printer go closer to the ribbon ,move the lever to number 9 and move the head over to the left side of the printer.push the head forward slightly towards the black roller and tighten the 2 screws again ,install the ribbon and move the blue lever to 1 and try printing again.
Hope this helps.Dezzi
