Prints a few lines, then blank

Replace the ink-cartridges, because they are just about empty.
When ink is pulled from the cartridge, there is just enough ink to print a "low-density" page,
or a few lines of text, but there's not enough ink to "freely" flow, on demand, to ink a full page.

get the print head cleaned at ur local ink replacer store

Need to replace the fuser.

Good day sir/maam, hi, when you test print it usually prints letters and no lines are printed. try first if the printer is setup to economy/draft or pictures, if lines are faded, the ink cartridges maybe dirty. manual cleaning is needed, the ink path starts from the ink cartridge to the cradle or carrier then to paper. so any dried ink that blocks the path can affect the printout. you can use warm water to loosen dried ink. remove the cartridges and cradle from the printer as you clean them.

HI since you tried replacing the cartridges and cleaning the printhead, try the steps below.

1.Print a Demo Page.

a.Press the Menu button of the printer.
b.Use the down arrow key and select Print Demo Sheet.
c.Press OK button.

If demo page doesnt have black ink or faded prints,the printhead on your printer require replacement. Call 1.800.421.6699

Thanks.

It sounds like your print head is dirty. Try cleaning the printhead in using the printers options, If that does not work replace the black printhead.

hi..reinstall your printer once.It will solve
your issue.
try it out..
thank u..
kindly rate my response..

What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem.
You can try googling. Phaser printer print heads or phaser printheads.
There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head.
Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads.
Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP.
The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.

My almost new F4100 printer is printing irradically, prints perfectly for two or three lines, then it fades to nothing, in a few more lines it prints perfect again. I can't find where to fix it.

well..did you run a test page?

or clean the print heads?

or recalibrate them?
