Here's what I'd do: Uninstall the printer and reinstall it. Another thing to check is cover. There is a little plastic thing that pushes on a switch to tell the printer the cover is closed. Sorry I can't tell you just where on the printer this is, 'cause I don't know. It could be this little piece broke off.
What can you do? Well, what I'm thinking is that the logic board on the printer is going bad. These days, most consumer printers can't be fixed--they are basically throw-away devices. You wouldn't want to pay the price to have it fixed anyway--they cost less to just buy a new one!

    The logic board is what makes the printer work. Sort of like a CPU and motherboard on a computer. It's the brains of the computer--basically a circuit board. If one of the chips gets damaged--say by a power surge or something, then it's toast and does weird things like what you are describing.

Image of last print shows up on presant print

This is usually caused by the left over toner not being properly cleaned from the transfer belt.
Open the printer front cover and close it. Wait for the printer to cycle. It usually make a little noise then stops. Then open the cover and close it again. Then print.
If the first page of the print out is clean. but the next page you print has a shadow of the first page, then you have a a problem with the cleaning mechanism.

Unfortunately the cleaner is part of the image transfer belt assembly which runs about $150 to $200. Unfortunately not terribly cost effective as compared to the original cost of many of these printers.

Good Luck.

I have a dell p703w. I tried to print something from my email and it came out blank. This has never happened before. Ink level is good, turned it off and back on, opened the cover and closed it.

Try running your Printer maintenance 'Cleaning' cycle from the printer properties (or Printer Panel menu option) and do a test print: your printer heads may be clogged from low activities (common issue with Inkjet printers!). Repeat a few times as required,.

Run cleaning utility

  • Clean the Ink Cartridge Nozzles
    • 1 Load printer paper into your Dell A920 Printer.
    • 2 Open the Dell Printer Solution Center on the computer. Click "Start," located in the bottom left corner of your computer. Select "Programs" from the menu displayed. Click "Dell printers." Click "Dell AIO Printer A920" and then click "Dell Printer Solution Center" to open the Dell Printer Solution Center.
    • 3 Click on the "Maintenance" tab and select the option that says, "Clean to fix horizontal streaks."
    • 4 Click "Print." This will print a nozzle print page, which forces ink through all of the nozzles to clean and unclog them.
    • 5 Print a regular document again to see if the print quality has improved. Repeat the cycle up to two more times to improve printing quality.

    Green light flashing wont print

    Many possible issues:
    1) the cover is open (close cover)
    2) Out of paper (add paper)
    3) printer can't pick up media (change media, change printer print mode setting or paper type selection)
    4) Paper jam (remove all media from the paper trays, press the power button once, remove the back cover and pull the jammed paper from that point then close the cover, reload the paper and try to print)
    5) Problem with the cartridge (remove the cartridges and then reinsert them, try a cleaning cycle. Alternatively manually clean the cartridges (remove them from the printer and power down and unplug the unit). Use distilled or bottled water and cotton swabs. Slightly moisten the swab and wipe the face, edges of the cartridges - do not touch the contacts or nozzles. Wipe down the underside of the print cartridge cradle walls. Reinsert the cartridges, close the cover and power up the unit. Calibrate the cartridges. If this doesn't help, replace the cartridges.)
    6) Loss of electrical contact between the carriage connections (press and hold the power button and open and close the top cover 4 times. Look at the resulting self-test print out. Remove and reinsert the cartridges and try to print. Next clean the cartridges and cartridge cradle as above. Replace the cartridges.)

    I hope one of these solutions work. Otherwise the printer needs service.

    Horizontal black lines across page.

    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
    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.

    My cuisinart coffee maker DGB-900 series beeps and wont make coffee unless I turn it on and off a bunch of times. The filter basket just keeps turning and clicking. I have cleaned it and checked to make...


    The machine will not run if the covers /for the coffee grinder, the filter basket and the machine itself) are not properly closed.
    It will beep and stop running if it is turned on when one of the covers is open or if one is opened before the end of the cycle. The beeping will stop as soon as the cover is closed.
    To start the machine again, press the ON button.

    If it still not will operate, head it back to the store.

    Hope this will help you

    Black won't print

    I have this same model printer and had this same problem. I solved it by running the cleaning cycle repeatedly (30 times or more). It nealy drained the black cartridge, but they're cheap compared to a new printer ($100 for the mfc240c that replaced it). Press the ink button to the left of the display. Select "test print" and "print quality from the menus, then hit print. After printing, the display will ask if quality is ok. Press 2 for no. It will ask if the black was ok, press 2 for no, if the color looks ok, then press 1 when it asks if color is ok, then press 1 when it asks to start cleaning. In a minute or so, it will beep and tell you to press start. Once the sheet prints again, repeat the same sequence. I didn't even wait for the display, I would just press 2,2,1,1, each time it printed. At first the black section was blank, the one dash appeared, then two or three. I gradually gained on it until I had most of them working again, then let it set overnight and ran a few more cycles the next day and it finally all started working.

    Brother MFC 425CN will not print black

    Have a look at the bk cart. Did you fix it well into position by clipping the support above the cart?
    Can you see any difference by ink fuel before and after cleaning cycle? If there is no difference the valve is not open: drill a hole into the top cover and leave it open. Try another cleaning cycle again.

    I guess you mean that the printer displays: No cart.

    In that case open printer take all carts out, close cover and unplug machine from power for a minute. After reconnecting wait til machine demands carts. Open cover and reinsert carts as shown on display! Make sure that the carts are well positioned and the cart holder is clipped above the top cart cover! Run the cleaning cycle twice.
