What Do Black Low Mean On Lasterjet Pro Mfp M127fn ?

What do black low mean on LasterJet Pro MFP M127FN do it mean i need to buy a new print link cartridge ?

 

Yes, you toner cartridge is running low of toner so you should probably buy one soon before you actually run out. You don't have to put a new one in yet, but if you don't want to be without a printer for a couple days, you should have a replacement handy.

 

If you are ever caught out and there is a problem printing.....simply remove the cartridge, give it a good shake then reinsert it.
It should print OK for a short period.
By shaking it you redistribute the powder evenly inside the cartridge and it will normally be OK for a time

 

I have seen toner go flying all over the place after giving a cartridge "a good shake". Not fun. But I do agree redistributing the toner in the cartridge when low can give you a few more printouts. So I recommend removing the cartridge and slowly turning it over in a slow "rolling" motion, back and forth, and forwards and back a couple times.

You might also open properties before printing and selecting "Draft mode". This will cause the print to be in a lighter grayscale instead of dark black conserving the ink. These lighter printouts are fine for "file copies" and the like.

 

That's the way to do it.

And if you don't have the option of selecting 'Draft Mode', look at the Advanced Settings - Toner Save, Toner Density, etc.

 

If ever I get 'flying toner' I'll change to the 'slowly turning' method......thanks for that I've obviously been very lucky over the years!

 

Well, you don't ever want to get flying toner so I might suggest you switch to the slowly turning method now. It is not like the toner is caked and lodged in corners and needs a violent shake to be knocked loose and forced out of place. Slowly turning it over allows the toner to just fall out of its hiding places. The stuff is like dry flour, not old, hardened sugar.
