Poor print quality - halo/smudge effect

Recently my printer has started this halo effect,like a smudge, principally on bold black print, although it can be seen a bit on the magenta and yellow. Have cleaned all charger units, advanced beam array lenses, done colour calibration, replaced toner and even replaced the black developer unit, and cleaned the paper chute and ramp, and changed to the latest driver. Still the problem persists. Any one out there who can help?

Maybe the probem lies in the fuser this is a metal teflon coated tube (surrounded in fidly breakable plastic) with a halogen light running through the middle (for heat) it heats up and fuses the toner to the paper JUST before it leaves the printer (thats why the paper is hot when it leaves the printer) you can have the tube RE-tefloned for not much cost when i used to repair laser printers the company would post a re teflonned tube and i would send mine back so the client would not be without a printer while the tube was being re done - or you could just buy a complete new fused unit (not cheap) hope this helps

It will need a new printhead, QY6-0062-000, around $80.00. Leaving it sit and not printing just makes the problem worse, as more nozzles on the printhead get plugged. You get 90 day warranty with refurbished units and if it started out crappy you should have had a shop look at it, that model can print super photos! A new printhead will bring it back to life.

Bizhub C350 Black smudges on prints

Sounds like you may have a bad fusing roller. Run some blank sheets. If the smudges start to fade, that's your trouble. When the fusing roller is bad it doesn't clean as well, so when you run bold text or anything that has higher than normal toner coverage, there will be more build up on the fusing roller that then transfers to the paper.

Poor printing quality. halo/ghost effect

check if your cartridge has enough ink.
And try doing a maintenance task on your printer. Usually you can find it in the Printers application software or you can check the properties of the printer. Most of the printers have features on doing a maintenance like, paper feeding, deep cleaning, paper smudge realigning, etc. You can increase the printing quality also in the settings of the printer.

well, i hope this works.
Thank you.. :)
