Hi i am getting a "sheet set error" message. when loading media.

This is one of frequent error in this series.




as you know two types of media paths 1. roll media 2. Sheet media. In sheeteet media loading area, you can observe 'u' shaped(extremly right side where sheet media sits) plastic mould which paper passes through in it. This palstic mould contains paper sensor to sence the sheetmedia. If this sensor is dusty, printer will treats that sheet path accupied by media. The best method to clean this sensor is to blow pressure air in this sheet path area.bicycle pump is best for this process.. try it...

Either: the sheet you loaded is

misaligned.

Realign it again. See the Users Guide

for a short tutorial on loading media.

Or: it is an invalid size.

For supported media sizes, refer to the

Users Guide.

Or: the media lever is lowered.

Raise the lever.

Or: the cover is open when the printer is

initializing.
Lower the cover

These are the trouble shooting suggestions from the HP service manual

F24 Water temp sensor error. Failed sensor or heater. Remove your bottom panel and look for your tech sheet. It will give diagnostics and error codes. Manual and more HERE

paper sensor has been faulty of this printer..

You have to set up NOT "cassette"(in this case "cassette" means the front side of the printer where you are supposed to place a cd or dvd) Choose "rear tray" ! You might have changed the settings by mistake. I had the same problem. I was wondering why is the printer not taking the paper but i figured it out. Try the settings on the mini display of your printer.

hi!!! in that kind of problem maybe the paper sensor was defective and it can't detect the kind of paper you loaded to your printer.

It means there is a paper jam in the fuser (the hot part that fixes the toner to the paper).
Check if there is any sheet jammed inside your printer or if any sensor is in the wrong position.
If everything seems to be ok, you may need to replace the fuser.

If it's an older machine, try cleaning the Multi-sensor (next to the printhead with the scissors icon on it).

34 Incorrect Media message appears if the printer has detected a mismatch between the type of media requested by the user and the type of media actually loaded in the paper tray.

To attempt a resolution for this issue, please do the following:

1. Press the green GO button on the printer operator panel. Printing will resume, but the printer must go through a POR (Power On Reset) in order to clear the message.
   NOTE: The printer does not automatically reprint the page that generated the error message.
   
2. Verify that the media you are using is supported by your printer in terms of size, weight, and input source.
   
3. Using the printer operator panel, verify that the type of media loaded in the paper tray matches the Paper Type setting in the Paper Menu. Detailed instructions for navigating through the printer menus and changing the media type setting are provided in the C510 User's Guide.
   
   • If the media type setting is incorrect and cannot be changed, there may be an issue with the media type sensor. Proceed to step 5.
     
4. Using the printer's operator panel, verify that the paper loaded in the paper tray is the size listed under Paper Size in the Paper Menu. Detailed instructions for navigating through the printer menus and changing the paper size setting are provided in the C510 User's Guide.
   
   • If the paper size changes to an incorrect setting or cannot be changed, it is likely that the paper size guides in either the 250-sheet or the 530-sheet paper tray are not set correctly. Remove the media from the tray and verify the location of the media guides.
     
5. Power the printer off and then back on again.
   
6. Resend the print job to the printer.
   
7. If the error persists, you will need to contact Lexmark Technical Support for assistance. Please obtain the printer serial number before contacting Lexmark. If possible, call from near the printer as this will allow for the most accurate possible diagnosis.
   

Hope this will help you please let me know if it worked and don't forget to vote..

Try to check the paper media set on the plotter (roll/plain paper). It usually happens if paper media is not the same with the plotter setting. To change it, unload the paper, press the media button on the printer to the right media and load the paper again. It should work now.
