Lexmark x4850 ink refill problem

If you refill the regular lexmark 100 ink cartridges, you will not be able to use it because there is a rfid chip that track the ink usage. you will need to buy the 100a type which will let you print if the ink level is empty. since you have refill the 100 ink cartridge, you can swap the 100a chip to your 100 cartridge.

I have a couple questions for you.
1. Is your cartidge 42 or 42A? The 42 cartridge will not work if you refill it. I learned that the hard way after paying to have it refilled and I got it home and it would not print. If you are using the 42A refillable cartridge, your ink levels will not reset. I called lexmark to ask them after not bieng able to find any answers online. He said that because I am using the 42A, it will print but will not register the level. The only downside is I have to keep an eye out for fading so that I do not ruin the printer heads.

I hoped this helped.

“Lexmark does not support the refilling of its ink cartridges. Refilling the ink cartridges can cause them to leak, thus clogging or even damaging the print head.

There should be a dialogue box that pops up on your computer when the cartridge is low telling you to order new ones. Usually there is a box you can check to tell it to ignore that the cartridge is low. If you don't get the dialogue box, somewhere in your printing preferences you should be able to tell it to "ignore ink levels." There does not exist a cartridge that "does not contain this circuitry." There are no compatibles of these cartridges and all refills are of original manufacturer cartridges.

it is because the cartridges are non refillable..... they have a memory chip in them and can not be refilled except by lexmark thru their recycle center

Yes, most Lexmark cartridges as well as many other manufactures use something called 'Smart' Chips in the bottom of the ink cartridge. Usually unplugging your (about 10 seconds) printer resets the memory in the printer. Hope this helps!

Buy, and refill #34 cart. for black, and click close, then continue on the pop ups, and it will print.

There are a couple ways to trick it into accepting the cartridge. You can put a different one in, take it out and then put the filled one in. Or you can find a refill kit with instructions on what contacts to cover with tape and you have to do it 2 or 3 times to get the printer to reset. Sometimes you can shut off the computer and printer for 20 min and start it up again. Or you can get the sledge hammer and smash the stupid printer before it sucks up your life savings and vow never to buy from a company that profits from causing problems that they tell you can only be solved by using more of their overpriced solutions.
