Installed new black toner but it still indicates it is empty and nothing will print!

emptying the waste box is not recommended but should not cause solid black prints. solid black prints indicate a problem with the image formation, primary or secondary transfer, or laser units. reset all toners and make sure the toner rack is slid in fully.

First, check to see that a toner cartridge is in fact installed.
Open the toner access panel and remove the cartridge.

Check to see if it is indicating that it is empty. If so, replace the toner cartridge and wait for the error message to clear as the machine prepares the new cartridge for printing.

THIS SOLUTION IS FOR AN OKI C3400N ONLY

As I'm sure you know, that blinking amber light indicates that:

1. A toner lock is not fully "locked", or
2. A toner is empty, or
3. A drum is empty or near empty

The first question should be what does your C3400 monitor software tell you is wrong? I am assuming it said the black toner and/or drum needed to be changed - so you are fairly certain it is the black that is where the problem is? You may also have run the report from the printer that you get by pressing the "On-line" button and seen what is failing.

Assuming that is the case, and one or both of these signals an empty black toner, the problem may be in the new black toner cartridge. You can try this:

1. Make sure the toner "lock" on all toners is fully engaged - assuming they are

1. Open the top
2. Lift out the entire black assemble including the toner and drum components.
3. Keeping the assembly in the same orientation as you lifted it out, look on the RIGHT end.
4. You should see two metal contact points, near the top at about the same level as the top of the toner.
5. Just below these contact, you should see a small, rectangular hole - about 1/4" square.
6. If you look in there you may see what looks like a small piece of black plastic that covers the hole from inside.
7. If so, take a small pointed object (like a bent paper-clip) and gently reach in the hole and touch the small plastic piece on the inside that is covering the hole.
8. You should be able to gently lift that piece of plastic UP.
9. You may have to try lifting it a time or two, but it should stay UP if you have a new black toner installed.
10. Once you have it UP carefully reinstall the assembly.
11. Close the top and let the printer recycle.
12. You may need to try this a couple of times to get the plastic to stay up on your new toner.

So you understand, here is what may be happening. That little piece of black plastic actually sits in line with a sensor in the printer that monitors toner / drum levels. When a new toner is placed in, that piece of plastic should be UP, so the sensor can monitor the level. As the toner gets used, the plastic liece gradually falls down until it completely blocks the sensor - indicating the toner is empty. That is how the monitoring software knows how to signal you.

This has worked for me several times - most especially when I tried using non-OKI OEM 'compatible" toners - but no guarantees this will help you

toner ink full but printer status toner emty

According to the operation manual: If alarm light and data light blink every 5 seconds- TONER LOW (purchase more toner and have it ready when the 'toner empty' is indicated). If alarm light and data light stay lit- TONER EMPTY (replace toner cartrige with new one).

Print a Supplies Status page to see the actual pages printed...

To print the Supplies Status page from the printer, on the printer control panel, select
Reports Menu, Supplies Status, and then Print Supplies Status page.

If the page count from the Supplies Status page indicates that the toner should not be in need of replacement then you have a bad cartridge. Actually, the cartridge is probably fine but the chip on the cartridge has got a problem. Return the cartridge to O.D. and get another one. Unfortunately, chips that don't work properly in not all that unusual so HP has a pretty easy return policy.

Hope this helps.

Replace Toner with gen cartridge.

 

Or Take cartridge back as faulty after checking that it was opened and installed correctly.

 

Check display on printer for indications that maybe it needs one of the 3 colour toners indicators are Y,C or M

 

K is black

Too few manufacturers will allow their units to print in grayscale when a color toner is low or empty. The only way to get your unit working is by installing the required toner. By the way, start a budget to buy the transfer belt, drum unit, waste toner bottle and fuser unit. These are also consumables with a lifecycle.

(blinking every 5 seconds) Toner Low Indicates that the toner cartridge is nearly empty. Purchase a new toner and have it ready for when Toner Empty is indicated. (solid) Toner Empty Replace the toner cartridge with a new one.
