Printhead not compatible with printer - Dell P703w Printer

If your HP Designjet 500 is not detecting the new printhead, there could be a few different issues causing the problem. Here are a few things you can try to troubleshoot the issue:

1. Check the printhead connection: Make sure the printhead is properly connected to the printer. If the printhead is not securely installed, it may not be detected by the printer.
2. Check the printhead compatibility: Make sure the new printhead is compatible with your HP Designjet 500 printer. Using a printhead that is not compatible with your printer can cause issues with the printhead being detected.
3. Check the printer firmware: Make sure the printer's firmware is up to date. If the firmware is out of date, it may not be able to recognize the new printhead. You can check for updates by going to the HP Support website and downloading the latest firmware for your printer.
4. Check for any visible issues: Inspect the printhead and the printer for any visible issues that may be preventing the printhead from being detected. This can include debris or foreign objects that may have gotten stuck in the printhead or printer, or damage to the printhead or printer.

If you have tried these troubleshooting steps and the problem persists, it may be necessary to have the printer serviced by a professional. A technician will be able to diagnose the problem and determine the necessary repairs.

Hi
From the cartridge costs it looks as if the cartridges incorporate the printhead. If this is the case - are you using HP cartridges or compatibles. Sometimes compatibles don't work when the printhead s the problem.
If you are using HP cartridges then make sure the contacts on the cartridge, and on the printer are clean. Apart from these comments I'm afraid I'm also stumped.
Good luck.

Do you have a large older printhead or a newer small one?

Try Gateway Time Systems, they offer affordable time clock service and parts. www.gatewaytime.com

You can try to disassemble the printhead and check for contamination.
First remove cap 1

than using a small flat screwdriver disassemble printhead (engagement points 2 and 3)



Warning - a printhead is filled with 8 ml ink

After disassembly - clean the printhead with fluid compatible with pigment ink (for black color) or compatible with water based ink (color printheads)

during reassembly - don't forget to fill the printhead with ink (2/3 of its volume)

f the printer continues to post a 930 Printhead Error, it thinks the wrong printhead unit is installed.

• If the printer was recently serviced, make sure the correct parts were used. This is especially true if the parts replaced were either the printhead unit or the printer's engine/system board. It is in one of these two parts that the printer is detecting the problem. Note: If you are the person repairing such a printer, please be aware that parts from different, though similar, printer models may not be compatible with this printer. Also make sure to check the laser cable going from the printer's engine board to the printhead unit, as it reads that signal.
  
• If the printer was not recently serviced before this error occurred and powering the printer off and on does not help, the printhead unit and possibly the laser cable or the engine/system board to this printer may need to be replaced.

Any chance the ink cartridges, which are separate from the printheads, are empty or dried out? If the printheads were exposed to air for more than a few hours without an ink cartridge on top of them, they may have dried out. HPs are especially bad for this, and BTW, never use a non-HP cartridge in a D145 - the inks aren't compatible and clog up everything (at least it happened to me..) You could also replace all the printheads and cartridges, but that'll cost you more than a new printer.
