Hp laserjet 4250

While the line is showing up on the output pages.
Stop printing and put paper in the manual feed tray (tray 1).
Start printing again. As a page gets pulled into the printer about 1/2 way open the top cover.
Pull out the toner and look at the page inside the printer. If it doesn't have the grey/black line, get the fuser replaced. It is defective.

Hello,
The problem you are having is caused by the fuser. The fuser is the part in the printer that heats up and basically melts ( fuses) the toner to the page. The fuser has a heat roller that is coated with teflon, your fuser coating has worn off in spots so the toner is sticking to the roller and causing the ghost image. You will need to order a replacement fuser. You can do a search on Google to find a replacement, the parts number is RM1-1082.

I hope this helps, if so please rate our solution.

You are low on toner. Replace the cartridge.

toner cartridge defective -replace.

first u change toner
if problem presist
replace fuser assembly

You either have a defective black toner, a bad fuser or transfer belt. From my experence it is usually a bad toner cartridge. After you print a couple of pages, pull the black toner and see if there is anything on the drum. If there is try shaking the toner, sometimes toner does like dirt and clogs up. If you still have problem you will have to try another toner. I know that is not cheep, but I don't know any other way.

Before replacing the LVPS, I surely would replace the toner and transfer roller at same time.

Horizontal lines usually indicate a toner cartridge that is not cleaning properly.

A. If the distance between defects is 38 mm (1.5 inches), 47 mm (1.85 inches), or 94 mm (3.7 inches), the print cartridge might need to be replaced.
B. Clean the printer.

1. Clean the inside of the printer and run a cleaning page to clean the fuser.

Over time, particles of toner and paper accumulate inside the printer. This can cause print-quality problems during printing. Cleaning the printer eliminates or reduces these problems.

To clean the inside of the printer
1. Turn the printer off and unplug the power cord.
2. Open the top cover.
3. Remove the print cartridge.
4. With a dry, lint-free cloth, wipe any residue from the paper path area and the print cartridge
cavity.
5. Reinstall the print cartridge and close the top cover.
6. Plug in the power cable and turn the printer on.

Cleaning the fuser:

Run the printer cleaning page to keep the fuser free of toner and paper particles that can sometimes accumulate. Accumulation of toner and particles can cause specks to appear on the front or back side of your print jobs. To ensure optimum print quality, HP recommends that you use the cleaning page every time that you
replace the print cartridge or on an automatic interval that you can set up. The cleaning procedure takes about 2.5 minutes to complete. A CLEANING message appears on the printer control panel display while the cleaning is taking place.
To run the cleaning page:

In order for the cleaning page to work correctly, print the page on copier-grade paper (not bond, heavy, or rough paper).
1. If your printer model includes a duplexer, open the rear output bin.
2. Press Menu to open the menus.
3. Use (Up button) or (Down button) to scroll to CONFIGURE DEVICE, and then press (Select button).
4. Use (Up button) or (Down button) to scroll to PRINT QUALITY, and then press (Select button).
5. Use (Up button) or (Down button) to scroll to CREATE CLEANING PAGE, and then press (Select button).
6. Follow the instructions on the cleaning page to complete the cleaning process.
7. If your printer model includes a duplexer, close the rear output bin.

Check your Toner Carts.
Is the line a certain color?
Black perhaps?

Lift the door of the toner cart.
If you see a streak on your toner drum, you will see a streak on your paperwork.

Look at your fuser as well.
Is there a problem with the big orange roller?
BEWARE! Don't touch the fuser roller its EXTREMELY HOT!
Let the printer cool down before inspecting.

you need to replace the chips so it will read the amount of pages printed by the toner cartridge.This chip is only for measuring how many pages printed.
