Problem to see on screen how many toner i have of the catridge hpdeskjet 3920

When the toner supply not attached the properly than comes this problem.
Better way you open the toner and check all toner supply gear ,if gear is jam than you should replace the toner.I think your toner chip version problem or destination problem.

Bingo! =) Thats an error ))))

paper jam is of two types.1.while spolling half paper will come out tom tray.remain jammed in rollers.This can solve by switching the printer power off and remove toner catridge from printer.Then power on the printer.lift the top rollers cover and reset as it is.The paper will come out without any difficult.2.Paper jam inside the toner catridge by rolling itself to drum.Switch off the printer power.Remove toner catridge from priter.Unscrew the toner catridge cover screws.remove drum from toner catridge .Utmost care should be taken while removing jammed paper from drum.Reassemble as it is and set.

You have to purchase genuine toner catridge from toshiba dealer . after purchasing the toner
1) Open the front toor
2) Toner catridge is there on above of the drum unit, there will be lock for toner catridge cover on the machine, it needs to be opened
3)Rotate the toner catridge in clock wise and pull the catridge ,it will come out
4)Insert the new catridge and rotate clockwise at a time it will get enhance with toner motor
5) close the toner cat cover, front door, TURN ON the machine it will get rotate for few seconds (adding toner) then it will becomes ready

Please check for the cartridges and try to make copies.

Open the front of the face. Pull out the catridge and drum assembly carefully. Thier should be a yellow tab on the toner catridge press down and the lift the toner catridge out. Replace and reseat in printer.

sir,

You open the front cover, there you can see the plastic bag. on the side of the cover you can see the intruction regarding the removing and refixing. actually it will be in white like colour and having a black bottle cap.

And also after you taken the waste toner catridge. you can see one sensor below a pipe like that which is projecting from the drum unit , it is the waste toner path. Inside this the waste toner auger will be there. you just clean the sensor because you may also get the waste toner error by the sensor.

1. sensor below the auger after the waste toner catridge.
2. waste toner catridge outside and inside. dispouse the toner and also clean the otside part will cloth , beause some projections some holes like that will be there. i told na that sensor will be passing the signals through this waste toner catridge projection. If any toner in that projection then also the same. Be causreful while you are disposing the toner. You may intake and also your properties may be having the black coating like that.

any clarifications mail me at [email protected] .

try using a different colored catridge (may be yr friends own) and see if it prints. if yes then yu need to buy a colored ink for yr printer.

are you using non refilled genuine HP carts?
