Laser Group - Panasonic® 4420 Tech Tips - Updated 6/25/99

Drum/Toner: As we will mention throughout all of these updated tech-tips, for the first time in our eight-year history, we are now using our own private sources of supplies in the remanufacturing of toner cartridges. The reasons for this principally revolve around quality and consistency. We have now switched over to Laser Group toner and drum for the best combination of print density and cartridge life. While we have tested combinations which produced either darker prints or longer cartridge life, we have not found a combination of toner and drum which produces a better combination of density and cartridge life.

Note: We'll once again state that we do fewer than 5 of these recharges per months. On a percentage market share basis, this cartridge is less than 1/4 of 1%. We do not spend a lot of time experimenting with new supplies for this cartridge.

Although there are now replacement drums available for the 4420, we do not do the drum unit nor the developer unit at this time (and probably never will). In our mind, this cartridge is the perfect example of an "oddball" cartridge so we do not advocate wasting much time on it, at all. For those customers who need new drums, developer units, or corona assemblies, we recommend you shop around among the suppliers and see who offers a better price (or even a comparable price) than what your customer is currently paying for a new, OEM unit.

PLEASE NOTE: We are always ready, willing and able to provide technical support to any of our trainees on any of the cartridges we have taught them to remanufacture. In order to make your interaction with tech support as productive and beneficial as possible, we make two assumptions: We assume that you have followed our procedures to the letter and used the supplies we recommended during the remanufacturing process. If a cartridge is remanufactured in a manner other than what we prescribe or with supplies other than the ones we recommend, the extent of our technical support can only be "generic" in nature, since we will have no firsthand experience with either the methods or supplies in question. In addition, we assume that you have already done your "swaps" (as outlined in the troubleshooting section for each cartridge) and that you will be able to answer questions based on the results of those swaps before you call and ask for help. We appreciate your understanding in this matter.
