Re: HP 2430tn lj printer with 13.20 jam inside top cover...


This question is directed at Steve from the post above. I need to order the sensor you mentioned. Is that sensor located exclusively on the power supply (Part number RM1-1505-000CN)? Will I need to order the whole power supply, or can I order the sensor separately? It does not show it very clearly in the service and maintenance manual. Thanks for the help!

Re: HP 2430tn lj printer with 13.20 jam inside top cover...

A 13.20 error usually indicates that the engine controller is "seeing" paper in the duplex tray.

Remove toner cartridge and set aside.

Remove tray two.

Press the green button to release the catch on the duplexer tray. Remove any paper in the tray. Inspect the black plastic sensor flag to insure it moves freely. Inspect the two pivot points for the duplexer tray to ensure the tray is properly installed. Correct if needed.

Close duplexer tray, reinstall tray 2 and the toner cartridge and power back up.

If the error message returns immediately during the power-up cycle, the sensor on the power supply board for the duplexer tray is probably bad and the cost to repair exceeds the value of the printer.

Does it makes any strange noise when you start it up ?

HP LJ 4L paper jam light flashes indicating a peper jam after printer makes a grinding noise. What can be the problem?

You may be right about the worn gear as a factor but I used to have a LJ 4 and whenever it indicated a paper jam it was always right. In some cases, the jam was a tiny scrap of paper deep inside. It took a flashlight and examination of every bit of the paper path to find it

Why is my hp laserjet 2430tn printer making noise when i print

This is a common problem with these printers after they do over 60,000 pages & up to 150,000 pages. It is caused by a bush wearing in the fuser assembly ( the heated area where the paper passes through and then exits out of the printer ). You will need a new fuser or if you are capable of repairing the fuser, purchase the bush from a parts supplier.

Hp lj 2430 rumbling noise

This is caused by the wearing of gears that drive the fuser assembly situated at the rear of the printer. Also the pressure roller bushes in the fuser assembly are worn.

I have a hp 2430 paper jam 13.20.00 and can't find the problem

If the paper jam error first occurs just after you have replaced the toner cartridge (as it did for me), carefully look inside (with toner cartridge removed) near the rear at the fuser and there may be a black piece of paper sticking out and/or curled up against the back. I needed a flashlight to see it but still wasn't sure until I felt around and found it. It was the protective sleeve that was around the drum in the toner and when I replaced the toner I missed it. When I first powered up the printer, the sleeve got fed partially into the fuser and the tail curled up against the back, making it practically invisible. Also, with that jam, the printer made no motor or gear train noise at power on so it almost had me convinced that the motor was bad. After removing the black piece of paper, the printer initialized normally.

HP LJ P3005 13.31.00 ERROR

As i can understand whenever you try to print with rear door closed printed page should come on top from top output roller however paper gets jammed.
Try to print a page using rear door open and it should come out from the rear drop down tray it printed page comes out successfully with rear flap open than paper gets jammed at top due to faulty top output roller.
However if the paper gets jammed at fuser with rear door closed than it is issue with fuser in that case you need to get fuser replaced at the same time replace 20 tooth gear next to fuser.

Hp Lj 2430TN Printer

We ran into this problem a lot when this series first came out. There is a simple sensor on the left hand side of the toner cartridge area inside the printer that physically detects that a toner is installed (or not). With the left cover off, there is a plastic bracket that holds a lever; unless it is not, then it tells you that you have no toner installed. Lame.

LJ 2430 Printing Blank Pages

HI there have you tried the toner cartridge as this could also cause this problem? Also change the transfer roller and are the bands going from left to right or from up to down. If the bands are left to right change both if up to down more likely to be the toner cartridge.

Hope this helps you
Thanks J
