HP Mobile 100 does not recognize color print cartridge

[goldline1]

I have three HP officeJet 100 mobile printers. Two of them will not recognize the color cartridge. I have cleaned the contacts yet they still give a blinking light.

Anything else I can do.... I am able  to take them apart and  it  appeares all the circ boards and wiring is good.

Thanks,

Larry

Hi @goldline1,

Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I understand you are having issues with the HP Mobile printer not detecting the color cartridge. Don't worry as I have a few suggestions which should help you resolve this issue.

To provide you with an accurate solution, I'll need a few more details:

Did you replace the cartridge recently?

Did the error appear all of sudden while using an existing cartridge which worked fine earlier on the same printer?

In the meantime, let's try these steps here: 

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

Remove all the ink cartridges and then try to perform a hard reset on the printer.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Now insert the ink cartridges and then try to print a test page and check if it works.

Next thing, I would suggest here is to follow all the steps suggested in the support document for - HP Officejet 100 Mobile Printers - Blinking Lights

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!

I hope you have a good day ahead,

Thank you so much for the response and suggestions.

Yes,  this started relativly suddenly and the cartridge is recognized by the one HP 100 that is working properly. This tells me it is not a cartridge issue.

I will do the re-boot, per your suggestion, and let you know the outcome... fingers crossed 🙂

Hi Jeet,

No sucesss... nothing I do seems to stop the left (color) cartridge light from blinking.

Is this some kind of mechanical / electrical problem?
