"Missing or failed printhead"

[Gpensf]

My Photosmart 7525 printer has stopped working. The first sign of trouble was the black ink stopped printing then the colors. I replaced all of them even though it showed tha they were not terribly low. Once they were replaced I tried printing a document for work and this message flashed on the printer screen, "The printerhead appears to be missing, not detected, or incorrectly installed." Does anyone have any experience with this same issue?

Welcome to HP forums, I see that you are getting "Missing or failed printhead" error message.

Step 1: Remove the cartridges and printhead

1. Press the Power button to turn on the printer, if it is not already turned on. Wait until the carriage is idle and silent before continuing.

2. Open the cartridge access door. The carriage moves to the center of the printer. Wait until the carriage is idle and silent before continuing.

3. Remove all of the cartridges, and then place them on a piece of paper with the ink nozzles pointing up.

      CAUTION: 

   Do not leave the cartridges outside of the printer longer than 30 minutes. This could result in damage to both the printer and the cartridges.

   To remove a cartridge, press the tab on the front of the cartridge and then pull it up to remove it from its slot.

4. Lift the latch handle on the carriage until it stops.

5. Lift the printhead to remove it from the carriage.

Step 2: Clean the printhead

There are three areas on the printhead that need to be cleaned: the plastic ramps on both sides of the ink nozzles, the edge between the ink nozzles and the electrical contacts, and the electrical contacts.

Figure : The three areas on the printhead that need to be cleaned

1. Plastic ramps on the sides of the nozzles

2. Edge between nozzles and contacts

3. Electrical contacts

   CAUTION: 

Do not touch the ink nozzles. Do not touch the electrical contacts with your finger.

 

Figure : Do not touch the contact area with your fingers 

Follow these steps to clean the printhead.

1. Gather the following cleaning materials:

   • Several clean, lint-free cloths or papers. Coffee filters and glass-cleaning cloths work well.

   • Distilled or bottled water. Do not use tap water. Tap water can contain contaminants that can damage the printhead.

2. Lightly dampen a clean, lint-free cloth.

3. Use the damp cloth to wipe the electrical contacts from the bottom to the top. Do not go past the edge between the electrical contacts and the ink nozzles. Repeat this motion until no ink appears on the cloth.

4. Use a fresh, lightly dampened, lint-free cloth to wipe any accumulated ink and debris from the edge between the ink nozzles and the electrical contacts.

5. Use a fresh, lightly dampened, lint-free cloth to wipe the plastic ramps on both sides of the ink nozzles. Wipe away from the nozzles only.

   Figure : Clean the ramps

   

6. Dry the previously cleaned areas with a clean, dry, lint-free cloth.

7. Lightly dampen a fresh, clean, lint-free cloth with bottled or distilled water.

8. Clean the electrical contacts inside the printer by wiping them from top to bottom. Repeat this motion until no ink appears on the cloth.

9. Dry the area with a clean, dry, lint-free cloth.

Step 3: Reinstall the printhead and cartridges

1. Hold the printhead upright with the colored icons on the top.

2. Lower the printhead into the carriage.

3. Carefully lower the latch handle.

      CAUTION: 

   Leaving the latch handle raised can result in incorrectly seated cartridges. The latch must remain down to install the cartridges correctly.

4. With the nozzle and contacts facing down, slide the cartridges into their slots. Press down on the cartridge until it clicks into place. Make sure that the colored icon on the cartridge label matches the colored icon on the carriage slot.

5. Close the cartridge access door. The carriage returns to the right side of the printer.
