Make HP Officejet 6500 printers recognize its ink cartridges

We usually have problems with HP Officejet 6500 printers, since they refuse to recognize the ink cartridges we’ve placed inside them, whether they’re brand new, recycled or refilled.

We even considered the print heads were damaged, but this was a mistake: the problem persisted after these parts were replaced.

Replacing an entire HP Officejet 6500 headprint will cost you $45,00, a considerable amount to pay to replace an article that’s in perfect shape.

We’ve done quite a bit of research and have come to realize this problem is caused by a small sensor. This sensor is located on the left side of the mechanism that makes the ink cartridges move from one side to the other throughout the entire printing process.

Procedure to eradicate ink cartridge recognition issues on HP Officejet 6500 printers:

Step #1:
This procedure will help you clean your HP Officejet 6500 printer’s sensor, which is not recognizing the ink cartridges. We must press our printer’s On/Off button, located on the front side of the panel. The On/off button looks like this.

Step #2:
Open the gate leading to the ink cartridges. This will imply raising everything, the scanner included, to take a good look at the ink cartridges. Wait for them to reach the center of the printer and leaving the left side free.

Step #3:
Locate the sensor on the lower-left side of the ink cartridges; it will look like a small square. You must clean this section very carefully using a small piece of fabric to get the printer to recognize the ink cartridges.

Step #4:
Close your HP Officejet 6500 printer’s gate and wait for the ink cartridges to get back to their proper spot. You can now  print a test sheet.

Please verify the printer has properly recognized each ink cartridge. In case this doesn’t happen, you can contact us by leaving a comment in the section below this post.
