Then insert it. If that doesn't help, either
- either sell him a new printer matching the new cartridge.
- or offer to send it to HP so it can be repaired. However, if it's outside warranty that probably is more expensive than buying a new one.
If it's inside warranty and a new cartridge doesn't help, HP will repair or replace it.
I assume you read the manual about what to do when the right printer cartridge LED is intermittent? That should even convince the customer.

Hello everybody ! I have a costumer's printer -Hp460c printer- and it's got this kind of problem : the "ON" and "RESUME" LED are on , and the right printer cartridge LED is intermittent , so it does not print.So the main thing to do would be to substitute the cartridge to solve the problem , yet , the costumer " assures " me that another is the problem , not this , not the cartridge.Had anybody had a simillar problem ? Can anyone tell me what could I do to fix this thing ? Thank you .
