Lenovo LJ1900 s red light is always on and cannot be printed Emergency!!!! ）！！

Ink machine three light flashing processing method Press and hold the ink key and the paper feed key together on the control panel and then turn on, 3 seconds after turning on, immediately release the hand of the paper feed button, then the hand of the ink key is still pressed for about 10 seconds and then the three lights will appear and flash again, then you can let go of the hand, so that you can clear the ROM well, and the motherboard is OK. The purpose of this operation is to clear the waste ink counter to zero. In addition, this can be achieved by adjusting the procedure.

If you encounter this kind of three-light flash failure two years ago, all the motherboards were replaced, and then the motherboard was further repaired, and now it is OK just a few times on the control panel, which shows that the printer must be experienced and patient to troubleshoot.

Dual-lamp structure (green for power signal) (red for ink, paper, memory, and the latter two are usually flashing for critical errors).

The red light will be on in the following situations: (from normal to faulty).

1.The printer is out of paper (it can also be understood as not recognizing the paper).`

2.The printer paper is jammed, the sensor detects it, and does not give work (which can also be understood as sensor failure).

3.The cartridge is missing ink (some machines are non-detecting, see for yourself).

4.If the running mechanism is stuck in place, if the car does not stop due to mechanical failure, the machine detects this fault (check the car road and the clamping gear mechanism).

5.Memory routine error, restarting the host and the printer (basically can solve this problem, and increase the printer cache appropriately) can not solve the relationship between the ink cartridge or the inside has not been cleaned for a long time.

The preheating has passed, indicating that the machine self-test is normal. In your case, it is very likely that the substitute powder model is wrong!

Lenovo's printers have high requirements for non-original consumables, and they will alarm if they don't match

The toner cartridge doesn't work, or you just have to wait a little longer, and it will take 10 minutes. See if you report the error.

The red light alone is always on only 4 in the possible:

The lid is open, there is a lack of powder, and there is no developing unit or drum unit.

In your case, 95% of them are out of powder. Switching to a different cartridge should do the trick.

It feels like the internal parts are damaged, and it is recommended to take it to Lenovo customer service for repair.

Hehe, it's so simple. There's too little toner in it. I just ran into this problem last week and thought it was a big deal. Just fill it with toner.

4 possibilities:1The toner cartridge is not placed or is not put away.

2.The development is not put or not put away.

3.The front cover is not properly covered.

4.No powder.

According to what you said, it should have been powdered, right? It should be that the powder can't be filled, so change the powder cartridge.

Lenovo printer 1900 status red light,Prove that there is a problem with the device,Generally speaking, the device is unusable at this time,You can only eliminate the problem。

The most common problem is the problem of consumables, generally the consumables toner is used up and needs to be replaced, this is simple, directly buy the original consumables to replace. Or there may be a shortage of paper, just put white paper in the paper box.

If it is a little more complicated, it may be a paper jam, and the device will also have a corresponding prompt, showing the location of the paper jam, and you can open the device and take it out.

I really can't solve it, it is recommended to report for repair, after all, Lenovo's brand is very large, and there can be maintenance points everywhere, which is safer.

The red light is a attention light, reminding you that there is no paper, or the paper is jammed, or the machine has not been turned off for a long time, and it is time to turn it off, just restart it.

The printer's red light is a hardware failure, it looks like it should be a problem with the feeder, look at the paper roller under the machine, wipe it with a wet paper towel to increase friction.

Did you pull that pinion next to the drum?

Check to see if there is any shredded paper stuck inside the machine.

It is recommended to consult the printer after-sales engineer and consult the best 4008101234

The red light indicates that there is an error, check whether the paper is jammed.

Check for paper jams first.

Or maybe you have a printer status check in the printer driver on your computer. Look at what mistakes are reported.

The reason why the printer is cleared and the printer is lost.

Check whether the paper is jammed, whether the ink cartridge is placed correctly, whether the line connection is successful, and whether the driver is installed correctly.

The drive is not right.,Reinstall the drive.。。。

Yellow or so on means that the printer itself is malfunctioning.

Take it and check it out.

Nothing clears on it.

As upstairs said it was the printer itself that was a problem.

The number of times the yellow light flashes also contains different issues.

How many times has your yellow light flashed?
