Ink cartridge was changed, but machine won't work

You won't be able to print if one of the cartridges is out of ink. The printer will prime every once in a while thus the need for all cartridges to have sufficient ink levels to prevent damaging the printhead.

Reset the printer to factory settings
Turn off the printer. and turn it on again.

If still not working

Take out the cartridges, turn off the printer
Turn on the printer and put the cartridge again.

HP B8550 has no numeric keyboard, so those solutions won't help.

cartridge is not compatible, try putting old one and if work replace the new one.
if still not work then sensor or card is corrupted have to repair/replace them.
please check and post again here.

Your machine needs to be serviced.
replace the cartridge with the original one.
it can not print if one cartridge is missing or not original.

CL41, this is the one you are using for your cartridge.

Did you change your cartridge with brand new one or refilled one??

If you did with refilled one, the ink level won't go back with full.

-------------------------------------------------------------------------------
This is the method how printer measures the ink level.

1. Each cartridge has a serial number.
2. As soon as installation in printer, printer recognizes the cartridge by serial #.
3. And the printer starts to count the printing document.
4. After reaching certain print counting, the ink level will show "low ink"

So my answer is even if you refilled your cartridge, the ink level won't change,
since printer cannot weight the cartridge or.....some other technology to measure each color ink level.

Thanks.

This is common problem with Brother Printers. I am going to assume you are using Non-Brother branded ink cartridges. Brother cartridges have a cleanser in the ink that most generic cartridges don't have. This in turn causes the jets to clog and not allow ink to pass through them. The fix is to go buy a couple of Brother cartridges and do a cleaning with those cartridges. You may spend some money doing this as a cleaning wastes a lot of ink, but it will clean the injection lines and fix the printer. You could also consider buying a new printer. I know this is not the answer you were looking for, but it is the true answer. I just bought a new printer due to this fact.

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

The machine won't scan unless both cartridges are installed and have a good supply fof ink in them. I know the ink level has nothing to do with the scanning procedure, but Brother has them coded to where they will not work unless both cartridges are present and full of ink. Replace the cartridge and it should scan just fine.

When machine shows ink out, you must replace with new cartridge. If not the machine won work.
