Frequently Asked Questions
What toner cartridges does the C5850 use?
The C5850 uses four individual toner cartridges — black (43865721), cyan (43865722), magenta (43865723) and yellow (43865724). Each color is replaced on its own when it runs out.
My C5850 warns toner is low but pages still look good — can I keep printing?
You can usually keep going on the C5850 for a while: remove the low cartridge, shake it gently side to side, and reinstall it — this redistributes the remaining toner. Replace it when prints actually start to fade.
How do I clean the LED printheads on the C5850?
Thin white lines down the page usually mean a dirty LED lens, not empty toner. Clean the four LED arrays inside the C5850 with a dry lint-free cloth, then print a test page to confirm.
