Lj 3050 print cartridge problem

Check your manual for instructions about this type of problem. Are you using the ink cartridges meant for your printer? Sometimes using refillable cartridges instead of the manufacturer's cartridges can cause the printer to still think the cartridges are empty, and display an 'on-screen' message that they need to be replaced, which could stop the printer from engaging. I have a Canon Pixma printer, installed refillable cartridges, and now the unit displays a 'cartridges are empty' message on PC screen; but the printer still works. The system just recently went into a non-printable mode displaying a more convincing message that the black cartridge is EMPTY, and completely stopped printing. The solution to this: press and hold the Stop/Reset button for about five seconds, and it overrode the issue and started printing. Moral of the story, maybe its best to just buy the manufacturer's printer cartridges.

Try a new genuine HP cartridge.

YOU NEED TO LET THE PRINTER RE-ALIGN ITSELF AFTER INSTALLING PRINT CARTRIDGES, THE PRINTER SHOULD HAVE PAPER IN IT TO DO THIS, THE TEST PAGE PRINTED WILL THEN NEED TO BE PLACED IN THE PRINTER ON THE GLASS, PRESS SCAN, THIS SHOULS RESET YOUR PRINTER.

HOPE THIS HELPS!

Install old cartriage, if you still have it, let the machine tell you that it is empty, then go through the install process with one of the new ones.

HP Color LaserJet 2600n Printer - Installing Print Cartridges When a print cartridge approaches the end of useful life, the control panel displays a message recommending that to order a replacement. The printer can continue to print using the current print cartridge until the control panel displays a message instructing to replace the cartridge. The printer uses four colors and has a different print cartridge for each color: black (K), cyan (C), magenta (M), and yellow (Y). Replace a print cartridge when the printer control panel displays one of the following messages: Replace yellow cartridge, Replace magenta cartridge, Replace cyan cartridge, Replace black cartridge. The control panel display also indicates the color that should be replaced (unless a genuine HP cartridge is not currently installed). Change the print cartridge

1. Turn off the printer.
2. Open the front door. CAUTION: Do not place anything on the transfer belt (ETB), which is located on the inside of the front door.
3. Remove the used print cartridge from the printer.
4. Remove the new print cartridge from the bag. Place the used print cartridge in the bag for recycling.
5. Grasp both sides of the print cartridge by the blue handles and distribute the toner by gently rocking the print cartridge from front to back. CAUTION: Do not touch the shutter or the surface of the roller.
6. Remove the orange shipping locks and the orange shipping tape from the new print cartridge. Discard the shipping tape and shipping locks according to local regulations.
7. Align the print cartridge with the tracks inside the printer, and using the handles, insert the print cartridge until it is firmly seated.
8. Firmly close the front door.
9. Turn on the printer. After a short time, the control panel should display Ready.

10. Installation is complete. Place the used print cartridge in the box in which the new cartridge arrived. See the enclosed recycling guide for recycling instructions.
11. If a non-HP print cartridge is in the printer, check the printer control panel for further instructions.
    NOTE: When replacing or changing a black print cartridge, a cleaning page will automatically print. This helps prevent speckles on the front or back of printed documents. A cleaning page can also be generated using the control panel or the HP Toolbox.

common problem on the hp lj 3800, you'll notice if you shine a torch in the area where you found the broken pieces of plastic, there will be some more, it is this which is stopping the toner cartridge from sitting properly in the printer. Don't worry about the broken plastic the printer will still work ok.

The display will tell you that a Non-HP Cartridge is installed and Economode is Disabled.
At least, you can now print. The display will show back again to "Ready".

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
