HP CLJ 4600 - Printing fine but have a toner leak problem?
Toner leaks can be a very messy problem, but what could be causing
it and what to do?
The HP 4600 has been known for this issue and the magenta
cartridge is usually the culprit. The problem used to be due to
the long cleaning cycles originally set via the DC Controller
(RG5-6391). HP has since revised the controller, shortening the
cleaning cycle to prevent the overflow of the waste reservoir.
The DC controller revision must be a 6D or higher. This can be
determined by viewing a configuration page under printer
information > printer number.
The versions run 62 63 64 65 66 67 68 69 6a 6b 6c 6d 6e 6f 70
If however, the DC controller has been changed and the problem
still persists, the next plan of action for most techs is to
change the High voltage power supply.
As a side-note: We have found it is almost always that the toner
cartridge itself (even if OEM), can have this symptom and would
need to be replaced.
