Re: Not ledgible

Your printers alignment is out thats why it wont print ,
Take out the ribbon and look on the ribbon drive assembly for a white plastic screw ? press the outer ring (also white plastic) down it should be spring loaded.while this is down use a small screw driver and turn the screw counter clockwise and than release the spring loaded gear it will shot back up.Try this a few times till the printing gets better.
Good luck

Scanner failure align the cartridge

To Align the new ink cartridge

The HP All-in-One prompts for an alignment of the cartridges every time a print cartridge is installed or replaced. Follow these steps to align the print cartridges from the control panel.
  1. Load unused, plain, white letter, A4, or legal paper into the input tray. note.png
    NOTE:If colored paper is loaded in the input tray when the print cartridges are aligned, the alignment will fail. Load unused, plain, white paper into the input tray, and then try the alignment again.
  2. Press Setup.
  3. Press 6 to select Tools.
  4. Press 2 to select Align Print Cartridge.
    The unit prints a print cartridge alignment sheet.

Load error

When trying to print on continuous stationery, the display may show "Online Single Load". This will occur if the printer is expecting to print on single sheet paper even though you may want it to print on continuous paper. To clear the error follow this procedure. • Take the printer off-line by pressing the Online key • Press the Setup key • Press the key under "Paperway" in the display • Select Tractor 1 (or Tractor 2 if fitted/required) • Press the key under "Set" • If the job still refuses to print try loading the printer with a single sheet of paper to clear the command. To do this remove the tractor feed paper and close the cover on top of the tractors but not the outside cover. You will see a guide into which put a single sheet of paper and press the key under "Load" in the display. • The printer should commence printing. If it does not, then press and hold the key under "LF/FF" to eject the single sheet. Now follow the instructions above again to select the Tractor. The display should read "OnLine Tractor Load". Load the tractor fed paper into the Tractors and press the key under "Load". The printer should now be ready to print. Check your software settings for the correct paper path type. Ensure that the display does not show "Manual" otherwise you will have to clear this error in the same manner as you have for Single sheet

3. Click the Maintenance tab and click Roller Cleaning. 4. Remove all sheets of paper from the auto sheet feeder, and click OK. 5. Confirm the message to be displayed, and click OK.

Paper won't feed

Inside of the machine is dirty.
If the inside of the machine is dirty, the printed paper may be smudged.
Follow the steps described below to clean the inside of the machine.
1. Ensure that the machine is turned on and there is no paper loaded in the Auto Sheet Feeder.
2. Place A4/Letter-sized plain paper in landscape orientation, horizontally fold it in half.
3. Unfold the paper, and load the paper in the Auto Sheet Feeder with the inverted-V edge down.

4. Select <Bottom plate cleaning> from <Maintenance>.
5. Select <Yes> on the Bottom plate cleaning confirmation screen and then press [OK].
Paper will be ejected.
If protrusions inside the machine are stained, wipe ink off the protrusions using a swab or such like.
* Important
Before cleaning, be sure to turn OFF the machine.
Paper feed roller is dirty.
Follow the steps described below to clean the paper feed rollers.
1. Ensure that the machine is turned ON and there is no paper loaded in the machine.
2. Select <Roller cleaning> from <Maintenance>.
3. Select <Yes> on the Roller cleaning confirmation screen and then press [OK].
The paper feed roller will rotate as it cleans.
4. Repeat this operation twice.
5. Load three or more sheets of A4/Letter-sized plain paper lengthways in the Auto Sheet Feeder.
6. Select <Roller cleaning> from <Maintenance>.
7. Select <Yes> on the Roller cleaning confirmation screen and then press [OK].
The paper that is loaded in the machine will feed through the machine and be ejected.
8. Repeat Steps 5 to 7 three times.
Inappropriate paper type is used.
Check to see if the paper you are printing on is too thick. See Paper Types You Cannot Use.
Note that smudging may occur at the top and bottom edges of the paper when using Borderless Printing. Ensure that the paper you are using is compatible with Borderless Printing.
Thick paper is used.
When printing on thick paper, set the Paper Thickness Lever to the right.
This widens the gap between the FINE Cartridge and the paper. Try this maneuver if the printed surface is scratched.
Media is curled.
If all four corners or the printing surface of the paper is curled, the paper may become dirty or may not feed properly. Use the paper after correcting paper curl as follows.
1. Place the printing surface face up (A), and cover it with a sheet of non-printing regular paper to avoid damaging the surface.
2. Roll up the paper in the direction opposite to the paper curl as per the figure below.
3. Check the printing paper to confirm if the paper curl is eliminated to within approximately 2 to 5mm / 0.08 to 0.2 in (B).
It is recommended to print on curl-corrected paper one sheet at a time.
The media type is not selected correctly in the printer driver.
On the [Main] tab of the printer driver, ensure that the [Media Type] selected matches the paper loaded.

In the [Print] dialog box of the printer driver, select [Quality & Media] from the pop-up menu, and then ensure that the [Media Type] selected matches the paper loaded.
Paper is loaded incorrectly.
Load in the portrait orientation regardless of the print direction of the Auto Sheet Feeder.
Ensure that paper is loaded correctly. Slide the paper guides against the paper stack.

If the machine has mainly printed 6x4,When you
go to print 7x5 the edges of the head and rollers
tend to be dirty and will leave the two stripes along

Enter/Ok - then click on the top far right ikon and
the screen you see will have a greyed out ikon
bottom middle - Now replace the print ribbon with
the white cleaning ribbon supplied with the machine
and the greyed out button becomes active - Click on
this button and the machine asks if you want to clean
it click Enter/Ok - About 10" of paper will then be
driven from the machine place the sticky pad as per
the drawing on it onto the paper and press Enter/Ok

Cant load paper into my printer



My name is Vikram Kumar Thumu, from India-Hyderabad. I have seen your message on the issue related to loading the paper    . I would like to provide my suggestions on the issue. I hope that this should work for you and will resolve the issue.


Please try below steps if you want to know how to load paper in to the Feeder.:

Important: When loading paper into the feeder, make sure you are using separated (i.e., cut) sheets of paper. Banner paper that is connected end-to-end should not be used unless you are specifically printing a banner.

To load separated sheets of paper:

  1. Obtain a fresh stack of paper.
  2. Separate the paper by bending it back and forth in an "S" shape before loading it into the printer.
  3. Place the paper against the right side of the sheet feeder, with the print side facing you.
  4. Gently insert the paper into the feeder. Do not  force the paper down into the printer.
  5. Squeeze the release tab and the paper guide together, and slide the paper guide to the edge of the paper.

Humid conditions may cause some sheets of paper to stick together.


If the issue still persists,  then I recommend you to look in to USER MANUAL that is provided along with Printer for instructions on loading Paper.


Well, for your convienience I'll provide you with steps that helps to access USER MANUAL.................


Steps are :

  • If the Lexmark P4300 software is already installed in Windows:
    1.  Go to Start, (All) Programs, and point to Lexmark P4300 Series. 
    2.  Select User's Guide.

  • If you have not yet installed the Lexmark P4300 software, you can find the User's Guide on the installation CD.  Do the following:
    1.  Insert the CD into the CD-ROM drive. The Lexmark installation screen should appear.
      • If the screen does not appear, open My Computer and double-click on the 4300 Series icon.
    2.  Click on the ?  icon to the left of View User's Guide (including setup troubleshooting).  You will be asked whether you would prefer to save the User's Guide to the desktop and view it from there (Yes), or to view it from the CD (No). 
    3.  Select the option you prefer.
  • This should resolve the issue for you.


     If you need any further assistance on the issue, you can mail me at . I'll be glad to help you.
