How many pages did my HP 3015 print from current cartridge?

Print a couple of pages. As the printer is printing open the toner cover. Pull the toner cartridge out and look down at the paper. If the printing looks good the fuser probably needs replacing. Before doing that, have you checked the toner cartridge.

is the toner cartridge original or reffiled.
Try with original one.
check if the image you print is correct printed on drum
to do this print something and when the printer start to pull the paper stop the printer by open a door. then pull out the toner cartridge and look the drum if the image seems ok If you see bad image you have problem with laser scanner or charge of drum.

HELLO

First of all,

Isolate to a wall outlet and not a strip.

Remove the cartridges.

Remove the power plug and then reconnect.

Reinstal the cartridges.

Try to do a copy direct from the unit.

NEXT

Print a self test page and check for Yellow or Magenta to rule out a partially empty cartridge.

1. Load plain white paper in the input tray.
2. Touch the ATM button ( ) next to the Setup icon ( ) in the lower-left corner of the control panel.
3. Touch the right arrow button ( ) to select Tools , and then touch OK .
4. Touch the right arrow button ( ) to select Printer Status Report , and then touch OK .

Check your printer driver. The printer is doing what the driver is telling it to do. Check the "printing preferences" button. Set it up to print "1 page per sheet".

Printed pages are VERY light, and the fuser temperature is low. The toner is not fixed on paper. Still it don`t give any errors. A detailed diagram of the power souce have anyone?

I need a bit more information. Does it print at all or just does'nt copy?
If it does'nt print at all the problem is generally the toner cartridge. Have you tried changing the cartridge?

the printer would print but a line with missed ink would be going down the right side of the paper

Try to change toner cartridge, I had this happen with my old laserjet 5, and it was a faulty cartridge on mine.
