Clean the large silver rod that runs through the carriage. It is dirty and not allowing the carriage to move as freely as it should. Ideally it should be left dry. Also change the ribbon. The same motor drives the carriage and the ribbon. If it has a bind, the same thing can happen. Hope it helps Ed

Why would my printer be printing very fuzzy print with lines through it.


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.

Printhead problem (black/yellow) on HP L7780


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 c00841893.gif 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 c00848391.gif
  2. If the carriage does not move to the left automatically, press and hold the Resume button (c00847980.gif ) 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 c00848392.gif
  4. Lift the printhead latch. Figure 4: Lift the printhead latch c00848393.gif
  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 c00847983.gif
  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 c00847984.gif
  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 c00847985.gif
  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 c00848394.gif
  9. Close the top cover. Figure 9: Close the top cover c00847987.gif
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.

Right side of label faded or blank after replacing printhead


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.
