Try to reset your printer it might fixed your problems:
To reset your device do the following steps.
While the printer is on, remove the power cord from the back of the printer, wait 30 seconds, and then plug the power cord into the back of the printer. If the printer is not already on, turn it on by pushing the power button. Try printing again. I think it will help you.
Try unplugging your printer from the wall outlet and leaving it that way for ~30min. If this does no help then it means that a fuse has burnt out somwhere in the device. Sadly there is no manual on how to disasemble a F4140, plus it would void your waranty. I suggest you try to return it under waranty, just don't say you don't know why it stopped working ;]
Power off the printer. Unplug the
printer's USB cable for 5 seconds replug turn on the printer.
If that fails power off the PC and printer unplug the USB cable at
the PC and printer replug and power back on the PC. After PC is
fully booted turn the printer back on. If this keeps
reoccurring please replace the USB cable and or try different USB
There are all kinds of printers and printing problems. It’s important to note at the outset that for safety reasons you should unplug your printer if you plan on working inside the device for any reason. In addition to the electrical hazard, printers (especially laser printers) can also be very hot on the inside, so use caution.
There are a few general troubleshooting steps you should take first, regardless of your printing problem. These will help solve most everyday printing issues.
Reboot. You’ll be amazed at how many printing problems simply disappear after you restart your computer. Also, reboot your printer. Sometimes, for no good reason, a printer will become wedged (it just stops communicating with the computer). Turning your printer off for a few seconds, and then back on, will usually get you going again.
Read the printer’s lights. Doing this can provide you with very useful clues. Is the power light on? Is the paper feed light blinking? Don’t be afraid to press buttons on the printer: Turn it off and on, reset the paper feed, and take the printer offline and bring it online again.
Check your physical connections. Is the power cord loose? Does the cable from the printer to the PC have a secure connection at both ends? Look at the connector pins on your cable. Are they bent? Try another cable if you have one. Check the print cartridges and printing mechanism. Is anything blocking the printer? Are the cartridges firmly in place?
Print a Windows test page. Access your printer’s Properties dialog box (follow the directions given above). Select the General tab and click the Print Test Page button. If nothing else, you can find out a good deal about your printer’s problem. If the test page prints, you have a problem with your application, not with Windows. Answer the questions as prompted and work through Windows’ Print Troubleshooter as needed.
Drivers. Verify drivers on the Details tab in the Printer Properties dialog box. Make sure the installed driver corresponds with your actual printer. Check the manufacturer’s Web site for updated drivers and browse the support pages on the site while you’re there.
Turn it off. Unplug the power cord from the printer & usb wait a minute. Plug USB in & than the power cable & turn it on. Next
Open the Printers folder. Right-click the icon of the printer in use, and then click Open . Click Printer on the menu, and then ensure that there are no checkmarks next to Pause Printing or Use Printer Offline . If a checkmark is present on either, click the menu option to remove it. If the menu shows Use Printer Online , click that option.
The squeeling I think has to do with a small build up of ink on the carriage.
What I do is I open up the printer top so you can see the carriage as if you were putting in a printhead and then you unplug the power to the printer when teh carriage is in the unlocked position. Now you can freely move the carriage back and forth. If you notice there is a clearish long strip going from one side of the printer to the other that is placed flat ontop of the entire metal inside casing of the printer. Clean that entire strip with a cloth or something. Now take a piece of paper and fold it a few times so that it ends up looking like a ruler you can say. Put the paper flat on that clear strip and then take the carriage and move it over the paper. Basically your cleaning the underpart of the carriage that touches that clear strip that is attached to the metal body of the printer. Move it back and forth and you will see ink being put onto the paper thus cleaning it.
Just close the case up, plug in your printer and the squeaking should be solved till next time. As for that light problem, don't know what those lights mean. If there is a problem with teh printhead or ink though it will always tell you on the digital read out, or at least should.
