Loose toner on printed pages

Toner doesn't seem 'fixed' to the surface. I clean each cartridge feeder using the user accessible sliders (recommended by tech support) and it seems to work for 2-5 prints but goes back to loose, smearing toner all too soon. Is this a heater issue?

You got it! - it's the heater, it not melting the powder to the paper enough. depending on the model, you can have it replaced or serviced.

Black tinting or scumming on pages


HP has a cleaning page that can be created to help remove toner build up on the fuser roller and I believe one for the drum also. Print "Menu Map" to find the cleaning page quickly. These are the two areas that need to be cleaned to help eliminate the "scumming". I would also look inside the device after removing the print/toner cartridge and if you have the toner wipes, remove any toner spillage inside. please do not use paper towels as they shred too easily and will mess up the transfer roller.

White lines when printing


Usualy white lines are a signal for you that is time to replace a toner cartirdge.
Your machine may inform you that you need to replace a toner cartridge, but sometimes the toner levels are low and the machine doesn't indicate that.
Another thing that you may try is to clean all toner cartridges using each corona wire.
If you need to replace your toner cartridge check this easy and helpful way to replace toner cartridge.

This happened to mine, only my thick edge was blue. My problem was that the little green slider that cleans the wire on the toner holder was pushed to the wrong side. (Sorry, can't remember technical term for the green thing or the wire! It has an arrow on it and it's pretty easy to spot.) Push it all the way back to the left until it clicks and it should fix the problem.

I just replaced the drum and the toner, now there is a dark streak down the middle of every page that prints, What is the problem?


the ink where it come out maybe dirty as it usually does when changing
go to the print operation and run a clean up system and see if the colours come up ok
this method may use a bit of your ink but if in business needs this has to be done and proves ok
if problem persists , than take the toner out and with a bit of alcohol wipe and a dry wioe afterwards, clean the outlet

Gray lines on the copies


If the toner is low that would cause a problem. If the drum is damaged that would cause a problem too. If you have recently (past month) printed successfully than you might have issues with copy surface. Does the line come when using the auto feeder? Replace/ remove/reinstall the toner cartridge and clean the copy surface. Repost if this does not solve problem.

Cleaning page


Ideally just replace the toner cartridge. But if fairly new, just clean the loose toner off from the old cartridge's printing surface by swabbing it as you manually turn the drum. If while doing this you notice black burned into the glassy surface of the toner cartridge or scars along the surface you'll just have to replace it. Happens once in a while, especially with refurbished cartridges.
